XFX Radeon 7950 running hot despite 6 fans and a nice airflow.
8 replies, posted
So a while back I bought this computer and I found that it can run pretty damn hot from time to time. I do some heavy duty stuff, a lot of rendering in 3D programs, so the temps before would hit around 90-100 pretty easily unless I blasted the GPU fan-speed to like 90% So I decided to get some more fans. 4 of them, in fact. Because previously I only had 2.
Installed them all, with a friends help we figured according to the laws of physics warm air goes up, so having two fans exhaust heat at the top while two on the side blow in air seemed good.
Aside from that I already had one that blew air out the back and one on the front blowing air in.
This is my setup currently:

Wanna know the problem? It still gets pretty damn hot. GPU fan at around 50 still, the temps are down to around 80-85. Not really a huge improvement. And now my computer sounds like a plane ready to take off.
Is my setup good for airflow? Or is the Radeon 7950 just really, really, really problematic with temperature?
Ooor is the improvement actually really good and I set my expectations too high?
Ooooor am I just pushing it a lot because of the tasks I put it up to? :v:
Yeah.
Set the fans so they create a positive pressure. That should help a little. Even with an after market cooler which does quite a good job my XFC 7970 gets very warm due to it being very hot in the case. High end quiet high cfm fans also work wonders.
If they'll fit these are 140mm fans on 120mm mounts. 98cfm 9-18db

If they don't fit these are 64cfm max 18db

I'm running 3 polimatechs and one couger and I have to complaints. You can really crank them up and it's not to loud.
If you're really concerned about temperature: you can look into buying a bigger heatsink/better thermal paste for your card and making sure it's applied properly.
I've been led to believe 90C is a very normal GPU temperature. Mine has been running at 90C for several years and it's still running ok, but I have a nvidia product. Not sure if I can speak for the radeon line.

If you can find one [URL="http://www.newegg.com/Product/Product.aspx?Item=N82E16835186064"]these[/URL] in stock they're great. Idle temps are a wee bit high still but max temp wont peak 70 on a bad day and 60 a good one. Plus the fans are quiet enough you can run them full blast and not notice.

Idle temps for me at the moment is around 30. This is for the 7970, though, or would that still fit okay on the 50?

Should be fine.
Awesome.
Final question - two of my fans are plugged in directly to the PSU so theyre pretty much at full power all the time. They don't show up in SpeedFan. Any other way to change their speed? :v: might help with the noise and all.

You must plug them into your motherboard to be capable of changing their speeds. I don't really know any other way.

afaik you can wire two fans together on the same motherboard output, if you feel like getting your hands dirty.

Get a fan controller.
