Chassis Qfan Controller

[halfpower]

Supposedly Qfan responds to the system temperature and the system load. Does anyone know how the controller obtains the system temperature? Does it get the motherboard temperature? does it get HDD temperatures from SMART? What does the Qfan controller consider a system load to be?

The reason I ask is because I need to tame three case fan. I'm thinking of putting the CPU fan on the CPU Qfan controller, and the rear case fan to the Chassis Qfan controller (connector located in the front). I plan to connect the front case fan to a Zalman Fanmate II (or maybe a potentiometer) and connect it the motherboard power fan connector (located in the rear).

many thanks

I dont know the Qfan sysytem, but i do have a HiLevel fan controller, and it has two NTC (negative temperature coefficient) resistors, which basically act as heat sensors. I have one connected to my CPU heatsink, and the other on my GPU heatsink. When the temperature of either reaches 45C, the fans get turned on, and by 55C they are running at full speed, and an alarm sounds if a set temperature is exceeded ( all of these temperature levels can be easily changed). I'd assume that your would work in a similar way. I can also turn my fans on manually, via a button on the controller.

Hope that helped.

Is Qfan the ASUS utility program in your bios???
