Crossfiring Visiontek 6950 and Twin Frozr 3?

post #1 of 2
Thread Starter 

I've heard a lot about how the twin frozr dumps back enough heat into the case to make it prohibitive, but with a setup consisting of one twin frozr and one of the new Visiontek cards with extra cooler, which I already own (pictured here

)
would this be a serious issue? I have not chosen a motherboard yet, seeing as this is for a bulldozer build, but the case will be an HAF 922. Both cards will be running at 100% capacity 24/7 as well. I'm not sure if the visiontek "dumps" heat back like a twin frozr, but the temp is typically around 80 degrees with ~60% fan speed at stock clock. If I can use these two cards without them heating each other up significantly I will, but I really need to know before I buy.

i think you will be ok but i would put the frozr as the bottom card so it doesn't dump all of its heat output onto your other 6950. you will be ok with a HAF case though as long as you have the maximum amount of fans you can and at high settings (not sure if you can change settings on HAF fans?) to maximise the amount of air that gets pushed into and out of the case.
and 80 degrees with ~60% i think is a bit too hot. I have my 6950 with unlocked shaders running at 880/1375 and it barely gets over 70 degrees with the fan at around 50-60%.
