HD 6970 Temps CrossfireX

post #1 of 13
Thread Starter 
Hey guys i just installed my two new HD 6970s.

And im wondering what the temps under load for the cards should be??

After running a few benchmarks the hottest temp it recorded was 90c on the dot.

Is this about normal or should i look into a slight case mod to allow more airflow from the front, i am using a Corsair 650D as my sig rig and the front 200mm fan is just useless ?

Create a custom fan profile with MSI After Burner.

Itll help with noise at idle and keep the temps down under stress.

well I have 2 6970's in crossfire on a 600t rig and I have abig gap between my two cards but have never seen them go over 80oC to be honest (front fan turned right up and HD cages removed).

try mounting your HD's in the 5.25" bays and removing the cages.. it makes alot of difference!

I was thinking of just mounting a 120mm fan instead of the top HDD cage, coz i only use up to bottom one ?

you could use a 120mm fan but might have to drill holes to mount it yourself..

if you want to sell your 200mm fans then I would be willing ot buy them

Load temps on a reference design 6970 is 91 on a single card... so i'd say your temps are good... On my gtx 580, just one maxed out at 78C in my high air flow Antec 1200 case... Sandwiching two together gave me 87/82C.
I'd say your temps are good, and adding direct fans to cool will definitely help. But the biggest thing for your cards will be to obviously space them out... They are literally boxes with an input fan to blow out the rear exhaust...

It matters on different factors. You all might have the best 6970's on the market, ambient room temperature, exceptional cases with no exposed wiring...

The website was my reference and I don't have an ATI card... referring to that, i'd say that you are safe... anything above 95C I would start paying attention...
