For Arctic Silver 5:
Carefully apply the thermal compound directly to the core of the CPU.
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.
You are thinking of how you put it on your IHS (the dot in the middle method), if you put it directly on a core (IHS removed) you spread it across the core.
The last sentence says "Properly lapped heatsinks with mirror finishes will only require a translucent haze", my 9500 is like a mirror on the bottom, so all I need is a "translucent haze" of AS5. But what I have is more than that, I have a very very thin layer, maybe not thin enough.
And I did check my volts with a DMM along the way, not every step but ever once in a while, I got lazy doing this because idle and under load the volts are the EXACT same as what I set them to in bios (but read lower in bios, SG, and MBM)
