hello some days ago, i installed a program called speedfan to see my computer temperatures. but when i closed that program, ALL of the fans started to run at 100% speed... so i quickly rebooted windows and uninstalled the program. but now it seems as the SYS fan runs at a speed of 1100 RPM!! and in the BIOS when i just rebooted PC, it sells me that my system temperature is 45 degrees. anyone know how to solve this problem??
