Step 8: Remove Fan and Heat Sink
- Remove the 3 screws (numbered 1, 2, 3) securing the fan to the heat sink.
- Remove the 4 spring-loaded screws securing the heat sink to the CPU (loosen in reverse order: 4→3→2→1).
- Lift the heat sink and fan assembly. Clean old thermal paste and apply new before reassembly.
Flip the laptop right-side up. Use a plastic spudger to separate the palmrest from the bottom case. Start at the left or right edge near the optical drive bay. Carefully lift the keyboard and touchpad out of the laptop
- The Fan: A centrifugal blower fan pushes air through a copper fin stack located near the exhaust vent.
- Maintenance: If your laptop was overheating, this is the moment of truth. Peel back the black mylar tape on the fan housing to reveal the impeller. Use compressed air to blast out the dust "carpets" that accumulate here.
- Thermal Paste: If you removed the heatsink, clean the old crusty paste off the CPU die with isopropyl alcohol and apply a high-quality replacement (like Arctic MX-4 or Thermal Grizzly). This drastically reduces temperatures on Ivy Bridge/Haswell chips.
