This is the auto fan controller, if you want the bios to automatically change the fan speed acording to the temperature (Usually for laptops, it saves power) Leave it on, when you change the fan setting manually, it turns it off, so, remember to turn it back on if you cant decide on a fixed RPM.

Now, There is on PWM computers, where you gotta set it from A0 to F9 (basically, numbers, A1, A2, A3, A4, Etc)

This is the fan speed, if your running a laptop, setting it to a high number, and hitting R, will tell you your max fan speed, (if its a high number like 100,000, the fan shouldn't run that fast, the fan has limiter on its speed. Green: (can be many different things, but, it is the fan speed) 0- infiniti, PWM= A0-F9 (if the image doesn't load: http //index.php?page=image&id=15560)īasically, Is the throttle amount, if you suspect the throttle to be on (processor slown down) Check this settingīasically, if you want the system to automatically apply a throttle when the system gets hot, if its a desktop, you should probably clean your fans, But, if you dont want throttle, turn this off.
