How do I clean the dust from the cooling fan on my HP Compaq Presario

Hi @maggie58 ,

Here’s a link to the service manual for your laptop.

Scroll to p.71 to view the necessary pre-requisite steps and then the procedure to remove the fan/heat sink assembly so that the fan can be cleaned or replaced.

Once you have removed it you may as well refresh the thermal paste on the CPU as it no doubt will be dried out and less effective.

If replacement of the fan is deemed necessary, the part number(s) for a replacement fan can be found at the top of p.71 as well.

Search online using the part number, appropriate to your particular CPU type, to find suppliers of the part.

Hopefully this is of some help.
