My friend has an fx-8320 with the stock cooler. After about 4-5 minutes after boot time, the computer totally freezes. He is running windows 10 and has never overclocked. When investigating the CPU socket, the heatsink is pumping out air and is at very high rpms. There is also quite a bit of heat off the CPU even though it is just after booting and at idle. We checked the thermal compound and it does seem a bit worn but shouldn't be a huge problem. All ideas and solutions are accepted. Thanks!
