How to Apply Super Thermal Grease
super thermal grease application - step 1 super thermal grease application - step 2 super thermal grease application - step 3 super thermal grease application - step 4 super thermal grease application - step 5

Step 1

Ensure the surface of processor and heat sink is free of small particles and debris, then steadily hold applicator approximately ¼” above the application surface.

Step 2

Gently press stopper to slowly dispense thermal grease onto the center of processor.

Step 3

Dispense around 1ml to 1-1/2ml of thermal grease (amount varies per application).

Step 4

Use a credit card or semi-rigid material to evenly spread grease across surface.

Step 5

Ensure surface is covered in a thin, consistent layer of thermal grease; then proceed to install heat sink or CPU cooling device carefully.
