    Hello, I am using an old ASUS A8Jr. I would like to know if there are any programs I can use to control the CPU fan speed? Notebook Hardware Control doesn't work!

    You can try SpeedFan, but if that can't control the speeds, then the fans likely cannot be controlled. I know my old laptop's fans could not be controlled.

    Fan RPMs are usually controlled by the BIOS, and there are only two programs (that I know of) that can control fan RPM; one is for Dell computers only, the other is SpeedFan.

    But speedfan doesn't list my fans? So that means I can't change the fan speed?

    Speedfan won't work on any new Asus notebooks. The fan controls are hard coded in the BIOS, but you can give I8kfanGUI a try. If that doesn't, then I don't think it's possible at all.

    The other thing I found back when I played around with the fan control on my old W3 using NHC was that the numbers that I ended up plugging in didn't correspond directly to the actual fan rpm as reported by one of the Asus monitoring utilities.

    The whole thing was too much trial & error, and I just ended up uninstalling it. If you turn the fanspeeds down in pretty much any older Asus notebook that this works on, it's possible that it will run hotter since the internal airflow patterns in many of the older models don't really allow constant low rpm fans to keep the system cooler than the stock BIOS settings - that's how it was on my W3 anyway, it always ramped up to the warmer temps unless I had the fan set near stock BIOS.

    Indeed it was trial and error but it worked. When I had my F3Jc, I tweaked the fan to be far more quieter but the CPU`s idle temperature increased from 38-40 to 48-50C. Needless to say, it felt considerably warmer.
