My setup is i7 3770 @ 4.5 r9 280 and 7970 lightning running cf @ stock speeds. 3770 is cooled with cooler master eisberg. radiator placed at top and 2 fans blowing out of the case. Another fan at the back of cpu blows out too. Just one fand blows in air which i s placed at the bottom. Need advice for cooling especially the gpu's. 280 hits 95 - 96 degrees
