Three remarks: 1) Prevent the fan from spinning madly while you use compressed air. 2) Before applying new thermal paste, first remove old old paste. 3) Thermal pasted is used in small quantities.

You may want to start by just spraying inside the fan area with compressed air without taking the machine apart. My Sony Vaio was sounding like a jumbo jet until I did that, and it's been running cooler ever since. It got so bad that it sounded like something was actually hitting the fan causing a tap-tap-tap sound, and after spraying the CPU core's showed 45-55 degrees instead of 75-85 degrees...

My comment - If you're going to contact ACER, do that first. If you open up the laptop and service it yourself, then call ACER, you've most likely voided your warranty... so calling them would accomplish nothing.

or put a vacuum cleaner nozzle (max power) to the air intake to remove (some of) the dust build up in the filter
