Also i fiddled around with the fans... i have 2x120mm case fans at the back, 2xcase fans at the front and 2xCpu fans on my 212evo. as the bottom rear case fan is at the same lvl as the HS i used that one to draw cold air to the cpu fan and the other cpu fan to pull the air out. i also changed the top rear fan to blow air out as the hot air in the case will rise to the top. I mounted a 2nd front case fan 1/2 way between the gpu and the 1st front fan, doing this have given direct cooling to the GPU with ambient air temp, plus the gpu has 2x HS fans on it aswell
