Thermaltake Smart Fan II problems...

I purchased two of these from a reputable vendor just today, and they were working fine. I installed them correctly and allowed them to be used in "manual" mode with a control knob.

A few hours later, one of the fans decides to have a mind of its own and will not turn down; it is stuck at full blast. At first I think it is my control knob which is faulty, so I switch to a known working control knob and it doesn't work either. To be on the safe side, I use the once-working control knob that came with the TT Smart Case Fan II and it doesn't turn down the RPMs (and thus the sound) of the fan.

It appears to me that I got a faulty fan, but I may be wrong. Any suggestions or comments?
 
Not to bust your chops or anything but I have to say, I never have luck with Thermaltake's products. The quality of some are good and most are complete crap. They have proven to me time and and time again that their QC is nearly non existant.
As for your fan, you don't even have to ask, it's a no brainer. Return that fan and hope to get one that's not faulty, good luck.
 
The manual control on those fans works by using a potentiometer to vary resistance. When the circuit is shorted, there is no resistance, and hence the fan goes at full blast. Since changing the control mechanism does not fix the problem, it is most likely in the product itself. My guess is that it's bypassing that connection all-together (maintaining a short). When there is no short or potentiometer, the fan works in its slowest mode, meaning there is already a mechanism of control in the product. My guess is some faulty work on the fan's electronics, I would advise replacing it.
