Steps
Shut down the laptop, unplug the charger, and close the lid. Turn it over on a clean flat table and keep the screws in a small dish as you remove them.
Undo the back cover screws with the precision screwdriver, then gently pry the cover loose along the edges and lift it off.
Disconnect the internal battery connector from the motherboard before you touch anything else. This cuts power to the board while you work.
Brush the dust off the motherboard with a soft bristle brush. Work lightly around the chips and connectors so you do not knock small parts loose.
Clean the CPU and GPU cooling fans with a small soft brush. Hold each fan still with one finger and brush the dust off every blade.
Blow short bursts of air through the fan blades and out through the side and rear vents until no more dust comes out. Keep the nozzle a few centimetres away.
Reconnect the battery, press the back cover down until the clips click, and refit the screws. Tighten them gently, not hard.
Boot the laptop and note the idle CPU temperature in a monitoring app, so you have a before and after figure to compare.
Open PowerShell and run 1..(int) | ForEach-Object { Start-Job { while($true){} } } to load the CPU. Watch the temperature, then stop and clear the jobs with Get-Job | Stop-Job and Get-Job | Remove-Job.
Tips and common mistakes
Work on a hard table, not a bed or carpet, so screws and tiny parts cannot disappear into fabric.
Do not let compressed air spin a fan freely for long, as it can damage the bearing.
If the temperature stays high after cleaning, the thermal paste may be worn and a repair shop should replace it.
Clean the fans every 6 to 12 months if you use the laptop daily in a dusty room or around pets.
Questions
How much does fan cleaning lower the temperature?
In this Acer Aspire 7 A715-79G case the CPU sat around 95°C before cleaning and about 60°C during a stress test afterwards. Your result depends on how much dust was inside and the room temperature.
Can I just use a vacuum cleaner on the vents?
A household vacuum can build up static that damages the board. Use a soft brush and short bursts of compressed air instead, or an antistatic vacuum if you have one.
Do I have to disconnect the battery?
Yes. Unplug the charger and pull the internal battery connector so the board has no power while you brush near the fans and connectors.
