Radiator / Fan Change

axer · 19 Nov 2011 at 11:25

Hi Guys,

Currently got a XSPC EX360 Radiator which doesn't perform as well as I expected (just about keeps my i7-2700k @ 70degC under load with nothing else connected to the loop :O).

Consequently I'm weighing up swapping the rad (it's very thin!) which has 6x 1450rpm GT's in push/pull with Phobya G-Changer V1.2 420mm rad with 3x 140mm fans in pull (currently looking at Akasa AK-FN062 and Akasa AK-FN063).

Am I likely to see a positive difference in performance and which fan is going to be better for the job (feel free to recommend a different fan). Unfortunately I can't accommodate 6x fans in push/pull or even 3x fans in push as the radiator is much deeper and thus there isn't sufficient room between the top of the case, radiator and motherboard.

I'm all ears!

There's something wrong if your see temps like that. The EX on itz on should see those sorry of temps let alone with the phobya. have you tried remounting your waterblock.

What's the full specs

Hi,

I've got this kit in a coolermaster HAF-X but with the extra 3 fans:

And yes I've tried remounting, have also spoke to a fellow OcUK'er with very similar temps to me (in fact his are a little higher).

Motherboard (Asus Maximus Extreme IV) is delivering a very stable 1.392-1.408v to achieve a stable 5Ghz O/C.

i got the EX360 rad and my cpu and gpu running both at 100% using msi kombuster and intel burn test, i get 61c on my i7 920 not clocked and 48c in my 480gtx under one loop with a single ex360 rad with only 3 GT 1850rpm fans on it.

i would look at why your not getting good temps. is your i7 overclocked? if not something wrong with your loop setup because mine is near 10c cooler then yours on a old i7 920 which apparently runs hotter then your one as yours is 3rd gen i7 cpu. And the fact that you are using 6 push/pull fans AND only cooling your cpu? somethings wrong and i dont think adding more rads or swapping would make much of a difference.

check for air locks

How do I go about doing that? System was actually an OcUK build (couldn't be bothered with the hassle) but there were loads of issues with it so have ended up re-doing most of it myself so far and temps have dropped from 80+degC to 67-70degC.

jonneymendoza · 19 Nov 2011 at 11:38

o and someone in another foru had same issue and the issue was he did not flush/clean his rad before use.

always do that first

pre built? no wonder. sounds like the rad hasnt been cleaned/flushed. to get rid of air bubbled, tilt your case around while the piump running.

seruously dude you should have build it yourelf, look at it now, your having to take it apart anyway

I've already tried tilting etc and it did get rid of bubbles and make the system quieter (could hear trickles to begin with).

With regards to buying pre-built, it came with liquid in it and I paid a £200 premium for the service so expected it to be ready out of the box (else, what's the point?).

flush your rad mate

axer · 19 Nov 2011 at 12:19

Will do chap, assuming that makes no difference though, what about my suggestion?

jonneymendoza · 19 Nov 2011 at 12:24

what suggestion was that? buy more rads? IMO it wont make much of a difference has a 360 rad is good enough to cool a cpu and gpu nevermind just a CPU.

axer · 19 Nov 2011 at 12:25

My suggestion was to replace the current thin 360mm rad with fans in push/pull for a thicker 420mm rad with fans in pull only.

The thicker rad should trump the EX as it is thicker (obviously !) and has more surface area.

However, I'd stick with this rad as a thin rad in the HAFX IMO is better.

jonneymendoza · 19 Nov 2011 at 12:28

Cool well like i said, imo it wont make much difference temp wise. you can quote me on this but any thin 360 rads are fine for one CPU block.

are u overclocking your cpu? what did u use to stress test your cpu? use intel burn test

It's mainly the volts that affect temps. Saw somewhere that a 2700k with 1.4v can get toasty under a 360rad.

axer · 19 Nov 2011 at 12:32

CPU is overclocked to 5Ghz with 1.41v as mentioned earlier, temps are recorded when using Prime 95 and IBT (Prime 95 tends to be around 67-68degC and IBT can get upto 72-73degC).

Ideally I want to get these temps down to low 60's to mid 60's MAX and hence weighing up my options.

Bottom line I guess, what would perform better in my HAF-X, a thicker 420mm rad with 3x fans in pull ONLY or the current thinner 360mm rad with 6x fans in push/pull.

jonneymendoza · 19 Nov 2011 at 12:52

get a 480 ex rad

axer · 19 Nov 2011 at 12:54

The EX is the thin rad isn't it?

jonneymendoza · 19 Nov 2011 at 12:58

yea soz i mean rx

axer · 19 Nov 2011 at 13:00

Ah okies, the fans would have to be configured for pull, that going to be an issue? (I'm thinking rad under the top of the case and fans above the case but under the plastic trim in the HAF-X
