I am building a new rig, but I have a question regarding heat transfer/management. Beyond what comes stock with the Antec Twelve Hundred, what other fans/ heat exchangers/ controllers are recommended to keep the system in a stable state. I put in a 1000W PSU, that heat has to go somewhere... I'd rather it didn't bake the new box, but I remain a bit clueless as to what is available.
I installed the CPUID monitor and the result was a max temperature on one of the 285 gpus of 78 deg Celsius. I imagine this is because the fans are experiencing higher pressure drop constraints from the adjacent 285 GPU below it in the case.
I am not sure if I can move the interfering card down to the next PCIe slot and keep it at x16. (I am using the 3 way SLi connector that came with the MOBO to connect the two cards - so I may be able to move the 2nd 285 down into the 5th PCIe slot without getting a new SLi bridge)
Everything else is golden from a temperature standpoint.
Is 78 degrees something to worry myself about on the video card (This was running 4 simultaneous sessions of World of Warcraft at ultra detail levels to stress out the cards)
your cards can handle up to the 80s-90s C without any damage, 78 is fine, and plus the easiest way of stressing the GPU is Furmark.... If you max out at 78c in furmark then you are good to go. Antec 1200 and CM V8 will give you more then enough cooling plus you can always increase GPU fan speed to cool your 285's down.
