For all Arctic Silver versions:
Spread the Arctic Silver thermal compound over the CPU core as shown in the photo to the right. The small amount from the photo in step 5 above has been carefully spread over the top of the core using a single edge razor blade. A razor blade or the clean edge of a credit card can be used as the application tool. You may use whatever tool you choose as long as it is CLEAN and allows you to control the application area and thickness.
The flatter the mating surfaces, the thinner the layer that is required. Stock processors and/or heatsinks with normal surface irregularities will require a layer 0.003" to 0.005 thick as shown below to fill the resultant gaps. (Equal to the thickness of about 1 sheet of standard weight paper.) Properly lapped heatsinks with mirror finishes will only require a translucent haze.
