Small-maybe dumb-question('puter cleanup)

Have computer sitting on it's side and cleaning out the buildup and dust bunnies and such. Think I remember reading somewhere-maybe on the other board-that when blowing out with compressed air that the fans can act as a generator/alternator and maybe produce unwanted voltages if fan spins. Is "old wives tale ", or is true? If true, will hold fan blade stat. and blow away. BTW, installed new hs/fan (Swiftech 370) on AMD cpu and it does as advertised by lowering cpu temp by bout 10 to 15 deg. F. .

 

Yes, it is true that the fan should be held.

I am not sure about becomming a gererator but they can overspeed in reverse.

PS.
Plsease don't use a metal screwdriver to hold the fan. Cause if blade slip, fan get chiped.

I read the same thing on another message board. I had never thought about it until then. But I guess it would be possible. So now I stick the end of a zip tie into my fans when blowing dust out of them.
