I have an old Dell power vault tower. This machine has high voltage power supplies and the fans in them are extraordinary. It is like I would be living beside an airport.
I've looked online for a while now to see if there's a way to lower the fan rpm on this to make the noise tolerable. I know fan can do it as I've played with the pin combinations to drop the fan speed you can barely hear it.
From what I've research I've found nothing I could use through bios or software to lower this fan speed. Is there anyone out there that has any advice to help me find a solution?
