PowerSpec B674 - fan runs continuously

Lavely

CPU temp is 34 degrees Celsius, no processes using much CPU at all, but fan runs constantly. How to fix?

This is an i5-8400 running Windows 10 Home

Motherboard is ASRock H310M-HDV/M.2 System Board

You can change fan settings from the BIOS under H/W Monitor. Did the this change all of a sudden?

Changes to Silent Mode in BIOS, no effect

PC is several years old, it did not always run this constantly

I was able to find an old sample of this system. Unfortunately the fan is straight to molex only. It runs full speed, no thermal control from the board. To control the fan speed you would need to replace the fan. It would be difficult to find a suitable replacement on this chassis. May be necessary to move the hardware into a new chassis.

I haven't opened it up to look yet, but are you saying I can't simply replace the fan?

When you say "hardware to a new chassis" do you mean new motherboard or new case?

New case. It's a 90mm fan, it's a little thicker than 25mm. It's going to be difficult to replace without modifying the case. If you want to bring it into your local store we'll check and see what we can do.
