Without knowing what this mystery paste is, I would just stick with the thermal paste already on the heatsink.
Also, never ever scrap off thermal paste. That ends up leaving scratches on the heatsink's surface. Not a good thing to do.
The thermal paste I have says on the tiny tube:
Silicone Heatsink Paste AK-100. What do you think, still stick with the pad?
I haven't decided whether I am going to oc yet, but let's assume I am.
But if I do then I am concerned with "permanent contamination" (see below)
from Arctic Silver's site:
"Thermal pad removal: Most thermal pads are made with paraffin wax that melts once it gets hot. As it melts, the wax fills the microscopic valleys in the heatsink and metal cap of the CPU. To minimize permanent contamination of the heatsink and metal cap, the thermal pad should be removed from the heatsink prior to turning on the computer."
So, is this a valid concern? or scare tactics to get people to buy Arctic Silver?
Thanks for your help!
