I built a computer, and I am using a Core™ i5-3570K Processor w/ Gigabyte GA-Z77-D3H Motherboard, and I am using the stock CPU Fan (that comes with the Processor), I noticed that the CPU Fan only spins when the computer is booting, then stops spinning when it has finished booting (when windows has fully loaded). When I go into my BIOS Settings, the CPU Fan still spins. But when it boots Windows, it suddenly stops. I have tried unplugging my CPU Fan from the motherboard and plugging it in again, but that doesn't seem to fix it. It is in the correct socket... does anyone know how to fix this? I'm quite sure it's a BIOS Settings Issue (please let me know if it is not), if it is how to do I fix it from the BIOS?
