I got a used i7 4790 running on stock cooler and a gigabyte b85m motherboard. It was running at 64 celsius before so I reapplied thermal paste. After it booted, it went to 47 to and gradually increased and now stable at 59. Ambient temp is at 26-29 give or take. I noticed that after pressing the power button, the chasis fan is already spinning while the cpu fan takes roughly 3secs to spin. It seems its trying to spin but it wont after turning it on then 3secs later it will eventually spin then I will hear the board speaker with the beep sound. Does it mean that the stock cooler is faulty? Or issue with the cpu?
