I use Speedfan to monitor and regulate my fans. I'm using a new FX-8350 with an MSI Gaming 970 board. Recently I've found when downloading a file using a browser, a game portal doing an update or a cloud service transferring a file I've noticed one of my 8 cores is maxed out and my system becomes very choppy. I've reported the issue to MSI and they suggested my CPU may be bad. Any suggestions? How can I contact Tech Support?
