Thermal Fan Assembly - Lenovo ThinkPad P70 Hardware Maintenance Manual

Removal steps of the thermal fan assembly
Note: Loosen the screws
When installing:
• Each screw is marked with a number on the thermal fan assembly. When installing, follow the screw
number to tighten the screws in ascending numerical order; otherwise, the system board might be
damaged.
• Do not touch the areas marked
• If the thermal fan assembly needs to be reused, apply the thermal grease to the thermal fan assembly, at
an amount of 0.2 grams. Either too much or too less application of grease can cause a thermal problem
