That is the second one I buy, first for my computer and the second for my wife's computer.
My Pc is built on an Asus Sabertooth 990FX R2.0 with an AMD FX-9590, and 16Gb DDR3 1866MHz memory. The PC case is the big tower Cooler Master HAF X with 4 case fans providing good air flow.
The Sabertooth BIOS (v2901) is configured with all "Auto - Defaults values" no tweaking no overclocking. The "Turbo core option" is turned on "Auto"
RESULT: Super powerfull machine remaining cool with no overheating: Idle temp maintained to about 30°C to 33°C. At about 80% CPU load, CPU temp never exceed 50°C !
My wife's PC built with exactly same hardware, configured in same way, but in a CM HAF 912 with 3 case fans... provides about same result.
I recommend the CM MasterAir Maker 8 with no hesitation... even with the AMD FX-9590 !
