Quick fan check...

[scaryjim]

Hi All,

A nice box of barbs and tubes arrived today which means I'm almost ready to put my rig under water, but being me I forgot something... fans for my rad!

Now, I've got an old PA 120.3 with the 25mm fan spacing, which I think means I can fit 140mm fans with a 120mm fan fixing: like these Thermalright TY-140s, which are PWM and appear to fit my requirements perfectly.

Any thoughts before I make my final purchase?

I thought the spacing only meant the distance between each fan.... if it was me id go with 3x 120mm fans to be safe but others should know if you can or not!.

if you dont get it then look at the yate loon fans (DS12 or something) as they perform very good and are <£5. Your pa120.3 should be fine with any fans really though.

Indeed - but due to the 120mm mountings these fans are 140mm at the widest point of the frame - this means 10mm more sticking out each side compared to a 120mm fan. On a 15mm spacing rad I don't think there'd be enough space but I'm sure I remember Gonz saying he used the Noctua equivalents on this rad before he sold it to me

I'd also like to use PWM fans if I can, which these are - in fact they're some of the cheapest PWM fans I've been able to find...

With the spaceings I think they should fit, the 120mm screw holes means they should fit with minamul fuss.

If the spacing is too tight you could try using two of these on the ends and a normal 120mm in the middle.

Not sure what these thermalright fans are like but for the price for a 140mm PWM fan I'd say they are worth the risk in trying them.

Are you going to use one the the Akasa PWM fan splitters?

That was pretty much my thought - couldn't find anything else PWM that looked half decent for < £10...

Thanks for the input though - always nice to get a second opinion!

I am indeed - £2.93 on Scan, so I figure I can't go far wrong

i had 120mm noctua fans, 140mm are pointless even if they did fit, but they wont as the spacings from screw to screw, not end of fan

[Pob255]

Thoes thermalright fans have the same hole spaceing as normal 120mm fans

[GoNz0]

a 15mm fan spacing equates to a dead fit with the fans butted up to each other

[Raz62]

I've got two of these http://www.scan.co.uk/Products/120mm...ing-Technology warped around my rad currently. They arn't as much of a gimmick as you'd think, can really push alot of air and don't make to much noise doing so

[scaryjim]

@Gonz: thanks for putting me right, you're spot on - my bad. Guess I'm hunting for some nice 120mm PWM fans again

[GoNz0]

price wise arctic cooling 120mm PWM fans, and not just price they also have FDB bearings the same as noctua !

and as an added bonus you can daisy chain the PWM's on them

[scaryjim]

Ignore that, I'd been looking at the Pro version *doh* Might have to nip down to Aria tomorrow morning (they're literally 5 minutes walk away )

RE-EDIT: OK, starting to confuse myself this is the Arctic Cooling websites pages on the Arctic Fan 12 PWM, this is the page for the Arctic F12 PWM. Could their naming scheme be any less confusing

Anyway, from that it looks like I *will* be nipping down to Aria in the morning!

[GoNz0]

yeh i spotted that and did wonder, might get you wet by the weekend at this rate

make sure you have a small funnel, lots of paper towells and a way of jump starting the psu to prime and leak test

[scaryjim]

The funnel will be coming with a small order from ChilledPC of other bits and bobs I could probably do with (like, you know, a fill port, a kill coil, tube clamps etc). Fans from Aria, by the look of it. Case modding starts tomorrow (I shelled out on some multi-tool accessories and some metal blades for my jigsaw earlier this week!) so pictures and build thread will happen.

Don't think I'll be filling this weekend, but it can't be too far off

[GoNz0]

fill ports are ok but i suggest a drain port instead in the form of a T piece with enough pipe to allow it to be fed out the case to a waiting tub

[scaryjim]

Any particular reason you'd suggest a drain port specifically? I don't intend to drain / re-fill the loop regularly, presumably I'd only need to do this if I was changing components? If I did put a drain port in, could I connect it to one of the bottom ports of the bottom graphics block, as that's going to be the lowest point in my loop!?

Oh, and I'll need to get a fill port either way as I'm going Res-less, so it'd be tricky to get water into the system any other way But I've not ordered yet so I can add a drain valve easily enough...
