Hi,

If you are going to use canned air to clean, be carefull to do when PC is off and cold. Try not to spray liquid into the PC (hold can upright). Looking at the inside of the PC I do not think canned air is going to help a lot. I would remove the back cover, remove the fan and clean and then place the fan again. If the problem persists, you can replace the fan.

You did not provide the complete model number. there are two letters missing at the end (Example: 22-b009nl) so that we can provide part number for fan etc...

Here are HP videos which show how to remove back cover and also fan:
