Windows 10: Laptop CPU fan making noise and probably not working properly...

My 8 year old HP Envy dv7 laptop still works fine, although the flex cables, connectors, etc. inside are weak both due to age related wear & tear, as well as the fact that I have opened my laptop a few times which I hate to do given how difficult they have made it.Since last week, my CPU cooling fan is making weird noise, and half the time I get the 90B error during boot:I can still boot once it shuts down and then everything else except the fan works properly. The fan seems to run with difficulty and makes noise.This is not my main laptop now, and so I have a limited light use with

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?
