Power Supply Fan. Unfortunately, my power supply fan gave neither, so I picked one based on the wind output (felt by hand). A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer.
The problem is that no matter what power suppky I put in there the power supply fan runs at full speed and sounds like a jet engine. It's a good question, and a topic of much debate as with most cases you have. A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer.
Here is how to select new part and repair.
I isolated the high speed fan noise down to the power supply.
Should I go ahead and get a new power supply? After leaving it off for a day, it now runs as though it's lagging. Installing a power supply into your PC is simple, and shouldn't take you long even if you're PSU intake fan up or down?
