Built for gaming. The original case fans were really noisy so I upgraded to 6 Noctuas (3 NF-S12A front intake, 2 NF-F12 push pull configuration on the Zalman LQ315, and a NF-A12 top rear exhaust). It is very quiet and they did improve the cooling at moderate overclocks up to 3.9ghz and at 4.0-4.2ghz overclocks I was hitting 61c in 10 mins under heavy load (Prime95). But it was built for gaming through mostly cyber Monday purchases and not to do extreme overclocking.
At the default clock it runs BF4 at 60+ fps on ultra.
BTW who said brown fans are ugly?
