ok, so i just cleaned my laptop fan using compressed air, the way they showed me on the internet, this is the first time i've cleaned it in about 2 years and i could see all the dust built up. Now it makes a whining noise, and gets louder as the fan spins faster. Is the normal? and if not, can i fix it?
PS - i have a Compaq Presario CQ60 and i cannot open the back to access the fan because i don't know how, but if someone can find a tutorial on how to that would be appreciated.
