Hi guys,

My new amd 7990 has been reaching temps of 91c under load after a few hours of playing. Is this too hot and will ot damage my card, I've ordered some more side pamel fans.

Thanks

You need some good side exhaust fans to suck away the heat put out by the core and vrm areas. A good intake fan at the front of your case providing cold air for the three gpu fans will help as well.

The 7990 is fine operating at those temps.

Get yourself a big slab of copper strapped to it and get some H2O in about it :D

But if that isn't an option, then experiment with a few custom fan profiles and perhaps add an additional intake/ exhaust to try to create a better airflow inside case. Unfortunately, it might take a bit of experimentation as just placing intake or exhausts haphazardly could have detrimental effects to the overall flow of air.

that's too hot, because that's what you get on prime 95 in full torture test..or close to it
 
I use MSI Afterburner. First thing, Disable ULPS. I have a slightly more aggressive fan profile:

Also enabling vsync will help reduce temperatures as it'll cap them at 60fps instead of having the GPU's working their socks off to get max fps. I have also dropped the volts a touch to 1.15v and put a slight OC on the GPU's @ 1050mhz.

I have an NZXT Phantom with 1x200mm & 1x120mm side fan intake, 1x120mm front intake and 2x200mm top exhaust fans, so plenty of airflow and it generally hovers around 68 -72c in games like Crysis 2-3, Hitman etc with everything maxed out at 1920x1200, ambient around 22-25c.

I was getting temps as high as 85c+ before doing the tweaks in MSI Afterburner.

Hope that helps.

My old card gtx 590 was fine in my case which is corsair 600t. I've bought the mesh side panel and 2 large fans so hopefully that will help!

Good thing you have the mech panel, as Corsair lines of Windowed panel cases whilst look good, all of them are relatively poor performance for GPU cooling.

For your mesh panel, add those fans as exhaust, and the temp WILL go right down. I would say at least down to below 85C.

So when I mount the fans, I obviously have them pointed so they blow cold air into the case

No the other way round.

You'd want to REMOVE the heat that's dump into the lower half of your case by your 7990, so have the fans suck the heat out of the case by having the fans blowing from inside to outside of the case.
