Just out of interest, how much did the WC system cost?
and what pump and radiator is that?
I was pondering on whether or not to get a WCing system, still not sure.
Not keen on the pink.
Awwww, that was my favourite bit! It will actually be UV blue, not that you'll really see that as there's not much chance of me taking a jigsaw to my lovely P180.
Goose, I got my WCing kit second hand on another forum - polarflo TT CPU, chipset and GPU blocks, XSPC 120mm rad, 1/2in tubing and fittings, Laing 5 pump, and an XSPC passive cooling reservoir - all for £85 delivered. I'm not gonna use the res as it's too big to fit inside and doean't go with the case outside. I'm toying at the moment with the idea of spending £50 on aquabay stuff just for pure PIMP factor...
Looks fine, however, you'll be lucky to get those bends from gpu to nb and nb to cpu with 1/2" tube. I'm using 7/16", which is bendier, in a deeper case, and it still kinks slightly. I think youve also possibly been slightly optimistic with the clearance at the top of the pump.
You can do really tight bends, if you get some of the 3rd one down, in fact, you can almost bend it double and it doesnt kink.
Hard to tell whats going on there, is it
pump->CPU->chipset->GPU->HD??->rad
thats a fair bit of heat going into one loop. Personally I would only run a CPU/GPU loop as that's going to give you the best noise/oc improvement in my experience (but of course it depends on lots of factors). Also I don't see any filling T, so maybe that pink blob top right is a res?
Yeah the pink blob in top right is a bay res.
loop is pump - CPU - chipset - GPU - rad - res ie. no HD included.
I was originally gonna leave off the chipset cooling as the mobo has heatpipe cooling which works very well, and I don't OC yet.
Clunk - thanks for the link - interesting stuff, have you used it? got a pic?
Cheers
I just bought a short piece of it, but didnt need it in the end, its handy to have in though.

Nice Dangel, real nice.
I've been looking about, and pretty much all reservoirs seem to come with 1/4in fittings as standard. Everthing I have is 1/2in.
I want an XSPC bay res now, http://www.specialtech.co.uk/spshop/...cat=548&page=1
what do I do about plumbing it in?!
Why thank you :) Well, you could just buy the right fittings for it - that's what I did for most of my stuff as i'm based on 10mm OD.

I dont know about anyone else, but if found Bay res's are an absolute nightmare nightmare to fill properly.
I ended up filling my system out the case, and then put it in after.
Lee
I've just got one of those big tube res' outside the case - dead easy to fill and people go 'oooooooh' when they see water bubbling around :)
Mind you, i've also got my radiator, pump, fans, controller etc outside the PC case - it's all in another case mounted alongside it - the whole thing then being on a customer made wheeled plinth.
I don't do things by halves me :)
Danger Den G 1/4" High Flow Thread Barb - 1/2" ID
is that 1/4in thread with 1/2in diameter fitting? so it fits in the 1/4in bay res screw holes, and the 1/2in tubing fits on the in/outputs?
Sorry for the silly questions, never done this before.
Oh, and dangel, I can understand the hollywood factor of putting it all on show, but the P180 is minimalist and kinda austere, so I don't think it'd work. Plus I don't wanna be cutting holes in soundproofed pannels. I actually have one of those bog showy XSPC finned Alu reservoirs, as it was part of the set, but i'm gonna sell it.
Re-Invented, I was expecting to fit it empty, then pull the res out the front 5.1/2 bay a few inches to access the fill port. Am I wrong?
Yeah thats the right way but as i said i found it a absolute nightmare, u not considered a danger den res there plain and simple but i found they do a brilliant job.
Found better temps with danger den res aswell, its been a long time since i played with watercooling as a lot had changed since then the bay res might be better.
Hope this helps

My Rig used to be:
Res >> Pump >> Rad >> CPU >> N/B >> GPU with Peltier >> Res
One quick question for people in respect to W/C'ing and a setup where you have a GPU, memory (and/or northbridge) and a CPU being cooled...
In respect to the diagram above, what are peoples opinions on having the GPU and the CPU on the same circuit? Surely which ever way round you send the flow of coolant, due to the greater heat put out by a GPU, wouldn't you either end up with the GPU "theoretically" heating up the CPU or the pre-heated coolant not cooling the GPU as much as it should if the coolant flows to the GPU after the CPU...
Wouldn't it be better to split the circuit into two and have one circuit with as for example...
Pump -> Split -> RAM -> CPU -> Join -> Rad -> Pump again
and
Pump -> Split -> GPU -> Join -> Rad -> Pump again
(Sorry, not very arty)
And potentially have a couple of flow meters to check both sides of the circuit to check they are both flowing equally.
Would that not be a preferable solution to either the CPU reducing the cooling on the GPU or visaversa, the GPU heat reducing the efficiency of the CPU cooling...??
It seems plausable but i find a better flow rate helps that will just end up bottlenecking back at the rad, but as said before been along time since i dabbled fully with w/c
Lee
heh hehe, when i said "the diagram above" I didn't directly mean yours... sorry, wasn't particularly picking on you... started typing the reply when it was on page 1... by the time i had posted... well you know... 2nd page already... was the OP's diagram I meant :)
But yeah, would be interesting to read any experienced W/C'd OC'ers opinions on single or dual circuit WC systems...
It's a good idea, but i'm not sure if it works - this is NOT an experienced water-cooler talking by the way!
I would've thought if it did work you'd see it done more often, but I don't think i've ever seen it done that way. Also I think the extra piping would increase the resistance and decrease the flow, decreasing overall cooling. My CPU rarely gets over 40*, and my GPU can allegedly get up to 90* (on air, stock coolers), so I think as long as GPU is after CPU it will work. Don't know about chipset temps, but like I said, I don't overclock.
Oh, and all the reviews I've read about the XSPC single bay res have been extremely positive - a lot of the reviewers started off skeptical of bay reservoirs and by the end were converted
Right, ordered. Watercoolingshop.com did it with free barbs of my choice included. I went for the black, as it fits in with the P180 colours - oh, and 'if it ain't black, it's whack', apparently.
The one in my sig/project log (if its big enough to warrant that title) is the only set up either ever done, however, I have done some fairly advanced fluid dynamics courses, and youd basically end up with the water in the most restrictive side of the loop slowing down dramatically. Depending what blocks youre using this will change slightly (you might not have as severe a problem as me with my very restrictive cpu block).
Given your set up I imagine the single rad may struggle to get it as cold asyoure expecting without some serious fan assistance. Youd be well rewarded by a transition to a bigger case and a 2x120/3x120 rad.
Not saying i disagree with you. I've certainly not done the fluid dynamics but I would imagine that surely, even if one side was slower than the other, that the movement of the faster side would effectively "suck" the fluid up through the slower side of the circuit but the sheer movement of the faster side's fluid bast the point where the 2 circuits rejoin?
And also, even if one side of the circuit was slower than the other, you could use flow meters etc... in an attempt to balance it out.
And lastly, surely in terms of the thermal transfer from the components to the coolant, the total heat transfer from each device has got to be better when the coolant isn't, for example, firstly getting heated up by the CPU, then the NB and then all that preheated "coolant" hits the already hotest part of the kit in the GPU...
I just think this is probably a really interesting line of thought and one that should be given more investigation. I honestly find it hard to believe that there isn't a way to make the heat transfer of a dual circuit far superior to a single circuit so that the "hot" coolant only combines the heat once the circuit rejoins just before it goes into the radiator...
If I understand correctly you guys are talking about a kind of figure 8 with one side going thru the CPU and one thru the GPU but using one pump/rad at the crossover point? This wouldn't make any difference to the temps as you have not changed the total heat input into the system or the heat transfer out of the system. It might acutally make it worse as you are increasing the pressure loss (longer pipe run) which would lower the flow rates (unless you use a beefier pump). To reduce the temps you would either need to use 2 separate loops (with 2 pumps/rads), a bigger rad, take some heat out of the system (eg northbridge) or swap the rad for a heat exchanger with a secondary cooling loop.
Oh don't get me wrong I did it like that because my case isn't big enough to fit it inside (plus it does heat the case and gets the coldest air possible). I didn't cut holes either - I fed the lines through the back of the case :) Anyway, glad you got it sorted :)
Not sure if we're talking about the same setup, couldn't quite visualise what you meant... anyway, i "knocked up" and quick MSPaint diagram for ya... just to show what I meant and save any confusion or talking at "cross purposes"...
http://img338.imageshack.us/img338/3104/flowtq6.jpg
EDIT:Hmm... I suppose it does make a figure of 8 shape... just imagined you meant it the flow was in a figure of 8... gah confusing...lol
That wont work well if the cpu block is a high restriction one, the water will follow the path of least restriction.
Better to either do it in a normal loop with a half decent pump and an adequate radiator/s, or do two seperate loops if there is room.
Fair enough... and with a normal loop in mind, what's the preferable order of components since the GPU is by far the hotest component in the circuit and essentially I would imagine if the GPU is 1st, the coolant could already be warm enough to add heat to the NB rather than remove it...
something like this maybe?
-> RAM -> NB -> CPU -> GPU -> ?
[EDIT: and this is where I would be slightly concerned about the effectiveness of the cooling on the GPU since there are already 3 component adding heat to the system even before it reaches the GPU...]
I'd agree - keep it simple - single loop will be fine. It's not like the water boils in each block - it moves through too quickly. Is cooling RAM actually worth it? I'd go CPU->NB->GPU.
Order doesnt matter, once it is pumping round, the water stays a similar temp throughout the loop.
The only thing that can be a pain, is if you have the res after the pump.
This is why, when you are cooling an overclocked cppu, NB, and GP (and whatever else), you need to get a radiator and fans that match, or ideally exceed the heatload of your system.
You can get an idea of you system heatload by using a PSU calculator.
Thank you both, that was pretty much all I was trying to establish.
(And oops, apologies to the OP for kinda hijacking his thread :embarrassed: :innocent: )
And OCZ do some quite nice WC RAM... and basically the same price as non-WC RAM but with a different surround on it... The OCZ WC RAM can even be used non-WC so can be bought as part of a system that would be converted to WC at a later date.
Doesnt matter what order, as has been said, it should stay a pretty constant temp all the way round. So long as you have the res as high as possible, and ideally immediately before the pump just choose the way that is neatest/uses least hose.
lol, yeah that's what I thought you meant :mrgreen: as others have said keep it simple and do a single loop - also if the NB already has a heatpipe on it I'm not sure why you'd want to add it to your WC loop, you're just adding heat and making the pipe run more complicated. For comparison, I have an Opteron 170@2.6G and a X1950XT in a closed loop and run at about 40degC idle/47degC load atm (10 degC lower during the winter)
Yeah, I had been thinking about the "split" circuit but with all the advice and comments people have contributed to this thread I'm definitely thinking about putting 2 seperate circuits in. Maybe I am being overly "protective" of ,y GX card, but with the ever increasing demands being put on them and the ever increasing heat therefore generated etc... I'm just a little concerned about the system (coolant) being hotter than it need be when it hits the GPU. I'm sure this probably isn't a "huge" factor, but I suppose my thinking is more towards getting the best cooling possible for the GPU (more so than the CPU/RAM etc...) due to the huge amount of work GPU's do nowadays. And I don't mind complicating the assembly of the case/wc system, thats part of the fun of building PC's... each new challenge, but I would certainly not be overly happy sacrificing potential cooling on my GPU for a slightly simpler build. And I certainly wouldn't want the OC'ing of my GX card to be limited by HEAT rather than the actual potential performance of the card.
Obviously, since we've all been discussing this topic (and very interesting it has been as well might I add), I'm still definitely thinking along the lines of a dual circuit but with everyones input, I think i will construct a dual "seperate" circuit setup rather than a dual "split" circuit. As regards the RAM, i do really like the idea of that RAM for two/three reasons.
The first being the obvious cooling of the RAM when OC'd (saves additional fans) but also because potentially it should protect hte RAM from heat radiated from other components which imho is probably MORE of an issue in WC PC's since there are more pipes/obstructions and probably a slower throughput of air than a normal air cooled PC. And since you can use it without watercooling as well because of the well designed aluminium fins, it seems like a good investment longterm for a WC project... if that makes sense...
Since you'll be investing in a new case anyway if you want two loops, i reckon youll be much better off with one 3x120 rad than two smaller ones. I would imagine youd struggle to find something that will fit two decent sized rads, and imo a 1x120 is too small to use on anything.
What's wrong with things like Clunk suggested way back (not sure if its in this thread or not) but things like heat exchangers (even the drive bay mounted ones nowadays) or dual output pumps etc...
There surely has to be "more than one way of skinning a cat"... I had no intention of trying to squeeze 2 of "everything" into my case? 2 pumps, 2 resevoirs, 2 radioators etc... that seems a massive overkill...
Sorry, when you said seperate loops i assumed thats what you meant. To get any real benefit out of doing it though i imagine youd need 2 radiators and 2 pumps at the least. You could go for something like the laing ddc with inbuilt res on this page:
http://www.coolercases.co.uk/acatalog/Pump.html
If youre only going to connect them anywhere each loop will eventually end up the same temp anyway, as it'll all get mixed somewhere. And if youre only planning on using 1 rad, then heats only leaving the system at the same rate anyway. To be honest, if you mainly want to keep the gpu cool, why not just cool that (id reccomend a cooler that covers the ram though, mine get incredibly hot), you can get excellent overclocks nearly silently using something like a scythe ninja anyway.
No worries mate, sorry it might have been my explaination of it.
Essentially, I am going to try and find a solution which will enable me to have the GPU and CPU on a seperate circuit... I saw quite a neat heat exchanger the other day (can't find the link for the life of me now) that fit nicely into a 5 1/4 bay... It was an interesting option... kinda food for thought if you get my meaning...
I was planning RAM wise to put the OCZ Flex XLC RAM on the same circuit as the CPU (before the CPU)... and am basically now just searching around for the various options (or alternatives if you want to think aobut it like that) to putting a "full" secondary loop in... for the obvious space reasons...
Maybe I should've explained that this is more a long term upgrade plan... call it experiment if you like... I'll reassemble my PC with a standard loop as suggested... once ASUS actually ackowledge they have a responsiblity to answer my support requests - it's been a week now of trying to get hold of them by phone or website and all I get is useless unhelpful and occassional replies. I'm really almost getting to the point where I am going to have to take ASUS's lack of response up with someone like the European Consumer Centre because I personally feel it is totally unacceptable to log a Suppport Request with them when their website specifically says if they don't respond in 48hrs it will be escelated to priority 1, and all they do to get round this is have "secretarys" answer the support requests saying things like "sorry to hear you have a problem, I'll pass this onto the relavent person who will get back to you..." except they never do...
I'm sure next week will pass just as this week has pass. God i wish I knew someone in the IT press business... I've explained I live in the UK and they even said they will pass my details onto their UK collegues yet when I rang ASUS UK to complain, the UK office told me (a) they knew nothing about it and (b) they dont' have a motherboard department in the UK anyway. Arghhhh!! How wrong was I when I bought ASUS expecting a good service in the unfortunate event of somethign going wrong... Gutted... Totally gutted...
oh Herulach, nice link... just been reading it while eating... that Eheim 1250 Pump (Pump Output: 1200 LPM) is a little on the "weak" side eh? ;) heh hehe
I think you are missing the point here mate :)
If you do it all on one loop, you need a good pump, and maybe two large rads, and maybe fairly powerful fans to go with the rads. Doing it like that will not require you to use two pumps, but you may need an extra rad.
You can do like I did, and have the CPU on its own loop, and put the rest on another loop (GPU and NB in my case).
As I said earlier in the thread, you really need to calculate your entire heatload, then buy parts that will dissipate that much heat, or more, otherwise, you will end up with temps that are similar or worse to air cooling.
For my second loop, I picked up one of those D-tek pumps, they are pretty small, and relatively cheap, compared to most (around £30). It is absolutely silent (to my ears), and is perfect for my GPU and NB. The barbs are removable and you could fit some that match the OCZ ram.
If you start faffing around with 5.25 bay heat exchangers, you'll just end up with an underperforming system. The money that you spend on that, would be better put towards a decent couple of rads.
If you dont have the room inside the case, consider mounting a rad externally (even a triple) on the rear 120mm fan holes, using a radbox or a hollowed out 120mm fan..
Just bouncing idea's around, how about, for example, in respect to the space taken up with 2 rads, one rad designed for 2x 120mm fans and something like this for say the CPU side assuming the heat output is lower on the CPU than the GPU...
http://www.xoxide.com/thermaltake-aq...-radiator.html
[Are there really no justification for things like those? Or are they really only useful as a 2nd additional rad in a single loop for example? Or maybe as an alternative to using two loops, have you ever heard of anyone say using one of those heat exchangers between CPU and GPU so a little cooling is done before the coolant gets to the GPU... Sorry, literally thinking as I'm eating... and each bit of info you guys throw in sparks a new line of thought...]
My case already has 5 fans in it and very good airflow... not particularly bothered about noise particularly... worked in too many noisey comms rooms over the years and kinda immune to PC "buzz" now..
(Edited Italic bit...)
Regarding the "calculations"... would you... *ahem* ... have any of those special "links" you normally carry around ;) you know... to say some 'examples'.. :)
[btw, i don't doubt at all any of what you are all saying, just incase it seems that way... I'm just genuinely interested and find all this conversation genuinely interesting and very enjoyable]
If noise isnt a problem, then you can get away with less radiators...not "lesser" radiators, just less of the good ones.
Look at this Thermochill graph, this is for a 120.2, and it tells you how much heat it can dissipate with 3 different types of fan at 7v and 12v, at a given flowrate.
http://www.thermochill.com/PATesting...lowrateLPM.jpg
As you can see, wattage dissipated is the Y axis, so go here and find out the wattage of your CPU (overclocked if needed), and your GPU (overclocked if needed), and for the chipset, you'll have to guess, I would say up to 50w is a fair assumption for a 965/P35 board, and higher for a 680i board.
Find out the type of fans you require, and work out from the graph, if that radiator is enough for your heatload.
You can find the full list of Radiators and their performance figures here.
Ahhh... brilliant stuff Clunk. Thank you very much (again!).
Yeah noise isn't a problem really for a couple of reasons.
Firstly, the reason i mentioned about comms rooms. Once you've spent an extended amount of time in a comms room with 40+ server and huge air con units blasting away, the "buzz" from a PC hardly seems noticeable. I currently have 3x 120mm fans and 2x 90mm (i think) fans in my PC and I only notice it when I switch it off (and I'm sat no more than 1metre away from it)... i.e. I notice the quiet more than the noise :)
And secondly, when I'm gaming so to speak, I normally play with head phones on anyway, for the immersiveness and in MMO's, for the immersiveness AND the additional use of TeamSpeak...
I'll have a look at those links and see what I can work out.
Regarding that other "idea"... with a good airflow through the case, do you think a drive bay heat exchanger theoretically "might" be a possible idea if it was sat between the CPU and GPU and was just there as an addtional "mini-rad" so to speak...? Just to help drop the temp of the coolant before going to the GPU?
Ah so, its possible, I could use one of those as an additional source of cooling BUT it wouldn't particularly matter where in the loop i put it as it just contribute to the overall lowering of said loop due to the speed of the liquid travelling round the system... Makes sense I suppose.
I used to be an organic chemist before I moved into an IT career (turned a hobby into a job so to speak) so I have reasonable understanding (well except for baring in mind, its been a LONG time since I was studying) of thermodynamics but its just more a matter of getting up to speed on things in relation to PC's... And I like asking alot of questions, its one of the best ways I find I learn from... Learning "hands on" and by firing questions at people who already know are just from experience the 2 best and fastest ways for me to learn more detail about topics I only have a basic knowledge of... I'm sure you'll get used to my "questions"... ;)
Anyway, thanks again for all the info and thanks for having the patience to answer all my questions.
I'll let you get back to having an evening Clunk.
You also have to keep in mind that each rad/exchanger will have an impact on flow rate as well, so while it might work fine on its own, if you were to put it in a loop with several other waterblocks and a couple of rads, it probably wont do anything positive for your temps, it might even raise them due to the flow rate dropping, of course I'm just speculating now :D
No no, its quite ok. Theorizing about things is always worth while. It's a great way of coming up with new idea's.
To be honest, I'm beginning to think along the following lines.
Once ASUS "pull their finger out" and get my board replaced, I think for now, I will put it back together "as was"... I'd assumed you'd probably read my PC spec and knew I had one of those Thermaltake Armour LCS cases (the ones that come with a basic cooling system and to be honest, it does alright. Better than I expected in many respects - I decided to go for that since I was just "dipping my toes" into a new area of IT that had always interested me but I'd never had the time to get invovled in and it was cheaper and an easier starting point for a novice which is where I believe they aim those cases for. I wasn't expecting earth shattering performance. It's abit like say if you wanted to try out fishing, you could of course go out and spend a couple of thousand pounds on a couple of competition rods and other equipment, or you could go and buy a cheap "all in one kit" and you've not lost so much should you not "get into it"... well, I have found I am finding this very interesting and AM "getting into it" so to speak.)
Anyway, where I was heading with that line of thought was, that yeah, throw it back together in its standard config (that was what I meant by the fact it had 5 fans. it has a dual rad with 2x 120mm fans at the front, 1x 120mm fan at the back, a 90mm fan above the 120mm and another 90mm fan in the roof between the DVD's and PSU) and then as a further line of "interest" I might invest in one of those Aquabay M2 2U 120mm Radiator as one thing I do have ALOT of in my case, is drive bays. The radiator even has drive bays built into the back of it so the air coming in to cool the radiator also passes past the drive to help cool it. But there's also an additional drive bay up by the PSU so its fairly flexible about how you can organise the case layout inside. Providing current funds allow, I might also change the pump at the same time to a "beefier" one.
The whole point about all my questions was partly just to "learn" more and find out if from my point of view, this was something I would get my teeth into without too much uneccessary expense (and again, hence the case) but also I was always quite aware that when buying this case, I was only getting "stock" parts and not optimised parts. But I didn't expect anymore than that. And I am pleased with how it gave me a taste and an easy initial first build of a WC PC.
Now, as I'm learning much quicker particularly with the advice of you guys, and also since I've got to take my PC apart to RMA this mobo, it's probably as good a time as any to have a further "tinker" to move more along the lines of optimising the cooling it does.
And finally, I LOVE my XFX GF8800GTS XXX Edition... it might "only" be a GTS but it OC's "almost" to the speeds of a GTX and has the benefit of XFX's OC'd shaders. It's the 640mb version as well so I'm very happy with it. It's been fantastic value for money and I couldn't speak more highly of it. I would recommend it to anyone as a mid range affordable card.
Anyway, the point I was making was I'm just thinking I'm so happy with the card that I really want to make sure it stays as cool as possible, lasts as long as possible but can also be OC'd as much as possible (within reason). The only time i noticed it getting a little "hot" when i play Oblivion, other games like WoW or Company of Heroes (even with the DX10 patch) just don't seem to put hte card under the load Oblivion does and basically, I really just want to optimise things and to "wrap a little more proverbial cotton wool" around my GTS baby... :embarrassed:
Ok, ok... yeah, I love fiddling with PC's... and yeah, any excuse to tinker with more toys "might" be another reason. "It's a fair cop guv! Guilty as charged..."
