Steps
Shut the laptop down, unplug the charger and hold the power button for five seconds to drain any leftover charge.
Turn the MateBook over and take out all the Phillips screws from the bottom cover. Drop them in a cup so none go missing.
Push a plastic pry tool into the seam near the hinge and run it around the edge until the cover pops free. Lift it off gently.
Unclip the battery connector from the motherboard before you touch anything else. This stops shorts while you work.
Hold the fan blades still with one finger and blow short bursts of air duster through the fan and heatsink fins until the dust is gone.
Loosen the heatsink screws in their numbered order, usually 1 to 4, then lift the cooler off the board.
Wipe the old grey paste off the CPU and GPU chips and the copper plate with an alcohol wipe until both are clean and dry.
Put a pea-sized blob of new paste in the middle of each chip. Leave it there, the heatsink pressure spreads it.
Set the heatsink back down and tighten the screws in order, a little at a time, until they are snug.
Reconnect the battery, press the bottom cover back on and refit the screws. Boot up and listen for a quieter fan.
Tips and common mistakes
Never let the air duster spin the fan freely, as it can damage the bearings.
Do not overtighten the heatsink screws, because uneven pressure gives worse temperatures.
Too much paste makes a mess and can spill onto the board, so keep it to a pea-sized blob.
Work on a clean table so you can see where each screw came from.
Questions
How often should I clean the fan?
Every 6 to 12 months if you use the laptop daily or keep it on soft surfaces. A dusty fan is the most common cause of overheating.
Do I have to replace the thermal paste every time?
No. Clean the dust first and check your temperatures. Replace the paste only if the laptop still runs hot, or if it has never been changed.
How do I know it worked?
The fan should run less often and the laptop should feel cooler under the same workload. Check your CPU temperatures before and after to compare.
