I've connected my 3 fans to the appropriate 3-pin connectors on the motherboard. The temperatures are around 45C so I tried lowering the fan speed somehow to address noise, but no matter what I do the fans run at a constant temperature (1.5k rpm for the CPU fan and 1k rpm for the two case fans).
I enabled Q-fan in BIOS and tried different settings. I ran the Asus Fan Xpert and changed settings. I ran calibration and it shows the same rpms for every % level.
I've had NO LUCK in using Asus' P6T fan speed controls. Automatic controls for the CPU fan seem to do whatever it is they're programed to do, but changes don't seem to work. And the changes available are CRAP.
In fact, ASUS P6T FAN SPEED CONTROL IS GARBAGE and the company deserves a public flogging for putting such crap into a retail product.
Oh, but it's a good board otherwise.
