Im still on the fence about the bad motherboard because right now the CPU is at 46 C with the fan set to really low speed. I am trying to figure out how to increase the speed. 46 is getting closer to normal right?
Yes, moving in that direction.
If you want full speed on the fan, disconnect it from the CPU header, plug the case fan into the CPU header, and plug the CPU fan into a PSU rail. It should already have a connection for that or have come with an adapter.
