Hey, my friend and I just build a PC for him and he got a second hand H40 and we hooked it up and got it running (I think). It used thermal paste from my Hyper 212 EVO because he didn't get any with it. The fans are spinning (REALLY LOUD) and I connected the wire of the fan and the block. So we booted it up in the BIOS and the temperature of the CPU just kept rising to 71 degrees. That's really really high for idle. We're using a FM2-A75MA-E35 motherboard and a 760K Black Edition CPU. Any ideas what is causing this?
