Question

PSU fan still running full speed.new updates

Apr 30, 2020 8:48AM PDT

Just a note,my computer is an Optiplex 9010 AIO.I recently got a new psu fan for my computer and its still running too fast.i checked it in diagnostics in BIOS and is running at a low of 4900rpm and a high of nearly 5500rpm.I tested using a different proven to work psu and fan from a computer with the same specs and even the good parts were making the fan spin fast.i even used the fan from the other computer and it was spinning fast,so it is NOT the hardware on my computer making my fan spin fast.Ive determined it is a software issue and I just updated my bios and nothing happened again,its still spinning fast.i need help
