As it stands I don't know, I game, and it sure heats up my 8 core 4ghz AMD. I don't think I could have too much cooling for it, even though I don't have any plans to overclock. At 65c it starts causing lockups, so it has to stay cool. I want it as silent as possible.
Power consumption or a hint a wattage/TDP might come handy here.... don't keep us guessing, provide just a tad little more info.
And the case and PSU you do have might give us some more clues as to how airflow and such are handled beside your CPU cooler.E.G. If you would have no case fans at all, the choice of cooler won't change a thing for your system. Additional GPU around, too?
Main GPU is a Radeon 7970 in the MSI version using Twin Frozr fans which runs silent at idle. I have the Radeon hooked to an Accell Displayport MST hub, so it runs six dispalys off of it when not gaming. I don't know if this effects the cards overall wattage or not. Give it a game to chew on and the fan spins up to maximum, and is loud. I haven't figured out how to solve that yet. I was thinking of water cooling, but the risk of leaks has stopped me.
I don't know the power consumption of the system, but it is has two ATI FirePro 2460's installed. They generate a LOT of heat (60-70c at idle), and are passively cooled. I'm looking to add one more passively cooled FirePro 2270 as well, but we'll see if I need it. These cards are supposed to be low wattage, at less than 20 watts each at maximum power. Some say they run at 13 watts typically.
I run two solid state samsung 120gb hard drives in a RAID, so not much noise there.
Case is going to be a Silverstone FT02, so the PSU will get air from the side vent into the case, so it doesn't effect case airflow.
The PSU runs silent at idle. PSU is a Corsair (Seasonic rebranded?) 850 watt.
Case fans will be the three 180mm fans tuned down to near silent, with a fan controller. Or that's the plan. I'm looking at the Scythe fan controllers, that display RPM, so I can fine tune it. Plus the 120mm exaust fan as well, which I plan to replace with a lower flow fan I have which I'd probably run at around 1000rpm.
