I just built a new system - P5K Deluxe, E6320, Lian Li V1200-plus ii, etc.
When I initially assembled it, the variable resistor / fan control knob on the back of the case worked correctly - it would control the fan between 1000 - 2000 rpm as indicated in Windows via PC Probe (Asus app).
I decided to try changing the direction of the Tuniq fan and the rear exhaust fan (since both were blowing "in" to the case as shipped from Lian Li). After switching the direction, the fan stays at full speed which is both overkill and noisy ;-)
The fan control knob and the fan have a quick disconnect so you can easily remove the heatsink/fan or fan control knob independently of each other. I thought perhaps I damaged it. I pulled out the fan control knob and tested it with me multi meter (which, unfortunately, has a broken LCD but the continuity monitor still works!). When I turn the knob all the way one direction, I hear the beep - which means the fan control knob/cable are probably not damaged.
I guess the only other possibility is that I damaged the control wire that connects to the fan. I did some google searches but didn't come up with anything. I'm not sure, but I thought you could control CPU fan speeds from most current motherboads via onboard PWM controllers.
So, I turned on the Asus Fan-Q and CPU Fan-Q (whatever they are called) and sure enough, the chassis fans do spin down from 1500 rpm to ~1000 rpm or so. But the CPU fan is not controlled. (The motherboard has a 4 pin connector for the CPU fan but I'm just using the 3 pins - +12, gnd, rpm - it's keyed so you connect it properly).
I installed speedfan and I am not able to control the speed of the CPU or the Chassis fans - although it does report back the current % that the chassis fans are at when the Asus BIOS utility slows them down.
So, any tips on how I can fix this other than ordering a new 120mm fan with speed adjustment? I would love to just control the speed from Windows if possible...
