Check this water cooling loop please? :)

Hi All,

Firslty I am fairly new to WC'ing so sorry if this is complelty wrong! (and sorry about the paint skills)

My question is. If i have access to a 240 rad and a 120 rad would that be fine to cool the CPU and GPU?
Or would I need to buy 360 rad?

As below.

Would this work or have i got this all completely wrong?

Any advice would be great.

EDIT - cant seem to attach pic.

pump - cpu block - 120 rad - gpu block - 240 rad - reservoir - pump was what I was advised ;)

Ah yer that seems to make more sence!

you may gain or lose 1 degree depending on the loop setup but it all evens out once up to temp anyway.

ideal is pump > rad > cpu > gpu but just sort it so its nice and neat and dont worry about it :)

or buy 2 pumps like i did ;)

Agree

Always like to put the pump before the rad but that's just me.

Make sure the pump never runs dry by putting the res before it.

If you can then certainly put it pump then rad then everything else, it really wont make much difference a max of 1C like gonz0 said. The more important thing is to just look at the best setup that minimises tubing, no point having a perfect loop setup if you have to add a metre of tubing! Less tubing = less strain on pump, can have it on a lower speed or just have better performance :D.


Depending on the CPU/GPU and the radiators and the fans whether or not you can cool it to decent temps. Generally though a 240+120 would be plenty! And it will cool similarly to a 360mm as its a similar surface area. Obviously if you have a mean cpu like a bulldozer at 5ghz dumping a crap load of heat into the loop and add it with a gtx590 overclocked then yes you will struggle with a cheapy radiator with poor fans :P.

Best way to decide on radiators is, what speeds will you run your fans at? Silence like the <1000rpm range or performance 1.5k+ range? If its the former id say the XSPC RX series eats everything, for the high fan speeds then youd want a Hardware Labs GTX series as they seem to be highly rated for high speeds, their SR1 rad is also a solid low rpm radiator.

Also for fans id recommend the scythe gentle typhoons, good fans they're and they have many different rpm variants :)

In all honesty unless your running the 3.4 gig prescott and a overclocked 590 then a good 120.2 will do you fine. I use a thermochill PA120.2 for a overclocked phenom 965 and a overclocked shader unlocked 6950 with 4 fans in push-pull and it never struggles.

I have mine as res>pump>cpu>gpu>120>240>res but then I have a jet impingement cpu block which thrives on higher pressure, thus going pump to rad increases my temps due to the pressure drop, no real need to run a rad in between blocks btw as the temps will only be different until the water warms up, after then it stabilizes.
