Is it normal for a variable speed cpu fan to STOP while the computer is running?

[GRagland]

I just got a Super Silent TC Pro HSF from svc.com. I turned on the computer for the first time and the fan started spinning, but then it slowed down and stopped like 5 seconds later. So i quickly turned the computer off again. I tried it 3 times, and it did the same thing. I emailed svc and they said this was normal for a variable speed fan (which the Super Silent TC Pro is). But i dont really believe them, on the box for the hsf it says rpm ranges from 1000-3500. So it shouldn't stop should it? Is this normal?

IMO, I wouldn't want the fan to ever completely stop..or think it should. Although I've ran mine w/o a fan (while I played around w/ hooking it up to my rheobus, etc), Had the timer in MBM set for 55C I think and after about 5 mins (while playing a movie) the alarm went off. =P ANYWAY, yeah, I wouldn't think that the fan should completely stop, have you checked the manuf website or emailed them possibly??

Manufacter's website is in another language. Its not a big company, but the hsf got good reviews. Hmm.. svc probably knows what they are talking about, but im still nervous to try it.

A HSF should never stop. You dont have it hooked up to a rheobus or anything like that do you?

well, i tried the hsf again and the fan stopped, but then started back up once windows loaded. when i am in bios the fan spins up and slows down and stops then spins up.. my temps are pretty cool, and i have the shutdown temp set to 60c. its really quiet, and i gues this hsf does that. someone else said there variable speed queit fan does something similar, and svc said this was normal. so all is good.

Ah, the Super Silent Pro.

I did my homework on this after seeing your other thread about your fan not turning on.

Apparently that's normal behaviour. The thing's just so damned efficient.
