My mobo is reporting the rpm at startup of the tuniq tower to be about 850ish rpm. This is strange in that the operating rpm is supposed to be 1000-2000 rpm range. I hooked up the rheteostat fan controller thing they provide and when I move it from hi to low, I hear no audible sound increase and no rpm change in the bios. I do however visually see the fan briefly stop and spin up again when I do change the controller value. I was wondering what kinds of rpms do you guys have for your tuniq and is defective or something?
