Ok so my dad put in the fan just now while i was away and I noticed that the fan that came with my processor is 4 pin and not 3 pin like my current fan. So I see that on the motherboard it has a 4 pin slot that says CPU FAN and a 3 pin slot that says PWR FAN. He put it in the 3 pin PWR FAN slot. Is this correct or is there something wrong. We bought the right fan, it fits perfectly. Thanks for the help.
If the fan on the heatsink is running, and the temps are ok then it should be fine. One important thing that some people forget: Did your dad put the thermal paste on?
