I built a gaming computer with a a6 richland apu and asrock pro 4 motherboard not overclocked. It overheats and reboots after bout 5 minutes. Package temp gets up to 65c. Have cheap aftermarket heatsink. Most people though say they that they run fine with stock heatsink. Jus ordered a coolermaster hyper x. Is something wrong with my apu. I can't even run minecraft for 5 minutes without it crashing and rebooting probably due to overheating
