I've go problem.. I buy all new parts on OC (asrock 990fx eXtrame 3, AMD 6100 fx, Geforce GTX 670, new case whit one front and one on the back 12 fans, just format and instal windows 7 and new drivers... all enabled quiet functions in bios... and still my fans freek out when I play or doing many things on the same time. My CPU fans show about 2400rpm and temp 39oC now but when I just turn on some game going up to 6399 RPM and temps going up to 52oC.. I try change speed on ASROCK Extreme Tuning utility but nothing change :/ Now I noticed - my northbridge are hot as hell, and I dont know what to do.
