For ages i've used the good old cables with a resistor in the middle to convert 12v into 9v or 5v to make fans run slower and therefore quieter.
I'm building up a couple of rackmount systems and theyve got 4x 4CM fans which blow air through the case. These run at 10,000RPM, shift a ridiculous amount of air and are very noisy. As the airflow is overkill, I'm tempting to 9v or 5v it, however question of reliability comes to mind.
Is 4 fans going through a single one of those resistors going to be too much current/shorten the lifespan or it considerabley? I would have assumed that in general a resitor would last almost forever?
Cheers
