So I installed 2 new fans in my case which makes it a bottom, side, and front intake and a back and two top exaust fans. My GPU, a GTX 760 is overclocked to the highest I could keep it stable but everything else is stock. Speedfan now reads the GPU at around 40C and my cpu 13C-30C. the first core being the warmest at 20 range on idle 30ish when im gaming. Is this too low? my house is 68F
