I have just finished building my Gaming PC and i have just booted it and everything seemed to be fine but i then noticed that the light on the Corsair H60 CPU Cooler wasn't lit, the brick which goes on the CPU usually lights up. Does this mean its not working i plugged the brick thing into the "CPU opt" on my motherboard and the fan into "Fan3" is that wrong? I know this is a really stupid question but am scared as i don't want my CPU to get damaged from over heating. And by the way everything else seemed to be ok CPU was detected.Thanks in advance. Oh and do you need to apply thermal paste or are you fine with the pre applied one?
