Need advice on cooling my 780 ti

post #1 of 9
Thread Starter 
Hello everyone.


So I'm using a Gigabyte GTX780 ti GHz edition inside of a NZXT 530 with a 140mm stock fan in the rear and a 200mm stock fan in the front with the case fan control on max. Reaches 86C in unigine.
The PSU has its fan pointing up.

I do not want to switch over to liquid cooling (yet) as it's too expensive for me and I'm scared of getting it wrong.


What can I do to improve the cooling of my graphics card?
I've been thinking of adding a fan on the bottom of the case to bring some more cool air in from the bottom.


Thanks.

what speed was the fan on the 780ti running at? remember, GPU cooler stock config is to keep as quiet as possible so it's not going to kick the fan on high unless the temp is actually hurting the chip.

it's entirely possible that the GPU fan is only operating at 60% to try to keep quiet since 86C is not actually hurting the chip.

airflow wise, i think you are doing ok with your current config for 1 GPU.

Thank you psyclum.

It was running at 60% and is using the stock fan configuration.


What would you recomend I run my fans at?
(Does it hurt the fans if they run faster for longer? E.g; at 90% fan speed, would it not damage the fans?)


Thanks.

Perhaps try turning the PSU so that it is fan-side down?
It's worth a try, my guess is that your GPU Cooler is trying to blow up at it's heatsink and your PSU is trying to pull air down, so the two fans are fighting for air, and your whole case's airflow is disturbed.
Plus, it's always good for a power supply to intake from the outside rather than your warm case air.

My 780Ti Windforce OC never went over 73C in my phantom 630, and never over 76C in my 350D, and I don't think the Ghz edition would run so much hotter than mine

spinning the fans at higher speed wont hurt it unless you have unfiltered intake case fan or are running negative pressure configuration for your airflow design. dust will kill your system way before wear and tear will biggrin.gif

you have to keep in mind that the GPU is one of the highest depreciated components in the computer along with the CPU. so by the time the fan dies, you would have long since retired that vid card and moved on to much faster GPU smile.gif

with that said... are you certain you want to deal with the additional fan noise? the GPU is not getting hurt by operating at 86C... if it was, then the card manufacture would have bumped the fan speed up from default config in the 1st place. biggrin.gif what you feel you are comfortable is really what it comes down to. you wont hurt the card by giving it more cooling,(unless you have a dust problem) but, just be ready to deal with the loud fan noise biggrin.gif

What Psyclum said.
The cooler the air going into GPU fans the better.
You might find the cooling guide link in my sig helpful.

Thank you for your help guys.
I've turned the PSU over so that the fan is now pulling fresh air from under the case.
It has decreased the GPU temperatures and I'm very happy about that smile.gif

I've also manually set a fan speed configuration; 10% fan speed per 10 degrees celsius and it's running a hell of a lot cooler now.
It very rarely goes above 60C now biggrin.gif
As for the fan noise, I'm not bothered by it. Either my surround sound covers the noise or my headset does.

And my case is a NZXT 530, so it has dust filters on all intake areas (except the one on the side of the case, but I'm not using that anyway).


Thank you very much for your help guys!

Good to hear it's working well now!

this case?
What others said+more:
Remove the hd cages if not in use
turn psu so fan is at bottom..
Replace front 200mm with two 120/140mm
add bottom intake fan
add top exhaust fans
add side panel intake fan

keep pc dust free by regular clean ups..that alone will gain you good temps already
gpu fan setup..use msi afb..set fan profile to custom to correspond fan speed accordingly to temps..
Start at 40% idle for temps from 25-45°c
55/60% fan for 45-65°c
60-75% fan for 65- 80°c

this will keep it in line
plus set update ms period to 800ms and check/tick force fan to update each period
monitoring tab:
Set ms update time to 800ms..
Temps- min 25-45 max default setting here
Fan - min 40% max 100%
the rest is upto you..
