Clean the aux part-cooling fan
Dust-coated part-cooling fan blades kill airflow and ruin overhangs. A quick brush restores crisp bridge and overhang cooling.

You'll need
- Soft brush
- Compressed air (optional)
Power off completely
Spinning fan blades + brush = bent blades. Always off.
Brush the blades from the front
Hold each blade still with one finger while brushing — spinning them backwards by hand stresses the bearing.
Blow out the grille (optional)
Short bursts of compressed air. Long bursts spin the fan way too fast and damage it.
