PC fan

[PrenticeBoyofDerry]

The fan on my PC seems to be running all the time, wasn't always like that. This has happened for a while, really should have done something about it!
More recently the fan or a noise from the processor tower has increased in volume, comes and goes but is concerning.
Does the fan need replacing, an overhaul or a good clean.
Appreciate advice.
Thank you!

Good clean, including cooling fins and any filters. Dust builds up and coats them, reducing cooling ability. Temps rise so the fan is told to spin faster to compensate.

Compressed air is the best method - either an airline or a tin of the stuff.

yeah compressed air is great, make sure you do it outside
