GPU cooling

zia · 1 Aug 2011 at 07:53

My twin forzor 580s are getting quite hot in my lian li p71f, the case doesn't seem to be able to cool these cards in sli,i have 3 intake fan 2x 140mm 1 x 120mm and 2x120mm exhausts.
If am running something like just cause 2 or bfbc2 both cards are hitting pretty much 87*c -91*c.
So i was wondering would it be worth me changing the fans? perhaps to some silverstone penetrators? and perhaps mount some 180mm or likewise either on sidepanel or on roof? bare in mind i wouldn't want it to sound like a hoover.

Thanks zia

I'd get some better fans and hook them up to a fan controller.
Can you space the cards out more by putting one in a PCIE x8 slot?

Unfortunely carn't move it to the lower pcie due to psu

Try getting some antec spotcools

Think i'll experiment with trying to place a spare fan on the ouside of the hdd cage pointing towards the cards and see if it gives me better gpu temps first.

Thanks for you input.

+1 for this, use one behind my 470's, does a good job.

Also use msi afterburner to set a custom fan profile.

How are the spotcools attatched to your case Setter?

I screwed a standoff into one of the holes on the mobo tray, then used one of the lian li mobo mounting thumbscrews to hold the spotcool in place. Does a pretty good job, keeps both cards within 1-2c of each other.

Do you have a custom fan profile setup for the cards on Afterburner or something similar?

Yep

Same here, im not that impressed with the stock fan settings on nvidia cards, on the 470's, above 60% the noise is loud, but i never notice it as when playing games, i use a pair of noise cancelling headphones.

When you say "does a pretty good job", what kind of difference do you see between using and not using it?

setter · 1 Aug 2011 at 18:36

At load or idle, the top card will run 10c higher than the lower one without the spotcool. Both are currently idling at 39c, in game they hit 69 & 71c respectively, oc'd @750/1500/1674.

Got my bits will see if this manages to cure the overheating

Is this the case you have here Zia?

If so, id like to see the results of using the silverstone air penetrator fans, im looking at theese for my Lian Li A70F as intakes.

Looks great. Keep us updates

Yes mate,i previously bought some yateloon 140mm but they didn't seem to help with gpu temps,so figured that since the fans were pretty much level with the gpus the penetrator would the best choice as they push air straight forward.

Yes, basically the same case i have here, funnily enough, im also using 140mm 1400 rpm yates as intakes. Theyre not too bad, but ive heard very good things about the ap fans, the focused airflow sounds ideal for our particular cases and gpu setups. The air has a fair bit to travel from the front of the A7*'s, hdd cage in the way doesnt help either.

Just to update the thread finally managed to fit the fans,They look very nice

The fans seem to shift fair bit of air,so far 5v seem the lowest they will go, unlike the noctuas and lian li stock fans i am unable to stop them with zalman fc1 fan controller which is a bummer but at 5v they are indeed very quiet yet still flow well,at 7v they still fairly quiet but at 12v they are quite loud.
the antec spotcool seem like a nice little fan very versatile.

First off tried just using only the penetrator using thier 5v setting launched just cuase 2 unfortunely the temp on gpus rapidly rose upto 85*c. turn the fans up full 12v and i did noticed a slight temp drop for both cards but it wasn't signifcant as i assumed it be,
Both dropped _3-4*C.i then tried the spot cool placed as both pointing on top cards as that one is the one that heats up the most.again the spot cool
didn't seem to efffect the temp at all,tried various postions but still no joy so have decided to remove it all togeather.
As it happen i purchased one fo these will see if it make difference
