Fan making grinding noise

Hi rdldn

If your fan is making a grinding noise, that would be an issue with the fan . . .

If your fan is running at top speed, then something on your system s using up CPU or GPU

Open Task Manager (Ctrl +Shift + Del)

Leave that open on the Processes Tab to monitor your system

When your fan is very busy, is your CPU or GPU at a high percentage?

(GPU - depending on your version of Windows 10)

If so, click on the relevant column header, so the arrow faces down

What are the top 5 processes listed?

FAN making extremely loud noise

If a clean fan is making a lot of noise, it usually means that the bearing is shot and the fan will need to be replaced.
