I have a Asus u36sd ultra book my hard drive died. Replaced the hard drive and re-installed windows 7. I tried tracking down all the drivers. I can't seem to find any drivers for fan control. Right now the fan on my computer never turns on so I keep turning it off when I feel its getting to hot. I tried using speedfan but it doesn't find any fans. Also when using the bios there are no fan control settings. Any help would be great thanks.
