Steps
Shut the laptop down completely, unplug the charger, and hold the power button for about 5 seconds to drain leftover charge from the board.
Touch a grounded metal object or wear an anti-static strap so you do not damage the internals with static electricity.
Flip the laptop over and remove every screw from the bottom cover. Keep them in a cup so none go missing.
Slide a plastic pry tool into the seam and work around the edges until the bottom panel lifts off. Do not force it.
Disconnect the battery connector from the motherboard so nothing can power on while you work.
Find the cooling fan, hold the blades still with a finger or brush, and blow short bursts of air through the fins and out the exhaust vent.
Brush loose dust off the fan housing and wipe the intake vents and heatsink fins with a microfiber cloth.
Reconnect the battery, press the bottom cover back into place, and refit all the screws.
Boot the laptop and listen for the fan. Run a game or benchmark to confirm temperatures and noise have dropped.
Tips and common mistakes
Never let compressed air spin the fan freely, as the blades can overspeed and damage the bearing.
Hold the air can upright and use short bursts, because tilting it can spray liquid onto the board.
Clean the fan every 6 to 12 months if you game in a dusty room or keep the laptop on a bed or carpet.
Work on a clean, flat table and photograph the screws as you remove them so reassembly is easy.
Questions
Can I clean the fan without opening the laptop?
You can blow air through the exhaust vents, but that pushes dust deeper inside. Opening the bottom cover is the only way to clear the fan properly.
Does cleaning the fan improve FPS?
It can help if the laptop was thermal throttling. Cooler parts hold higher clock speeds, so games run smoother and the fan noise drops.
What if the fan is still loud after cleaning?
Check that nothing is blocking the vents and that the fan cable is seated. If the noise continues, the fan bearing may be worn and the fan needs replacing.
