"it's actually made to withstand much higher temperatures, and yet still retain it's viscosity and heat-transfer abilities"
it could be harmful to the processor, it could release minerals that can cause problems on the components
the thermal paste properly applied should last for 3+ years on most processors and since you buy lots of it to put on almost 10 processors, the thermal paste still sounds good to me
What minerals might that be exactly? Any proof of that statement? It seems a bit implausible since wheel-bearing grease is specifically formulated to not only be used on metal parts on a daily basis, but is specifically made to prevent damage to them.
You check out a processor thats had that crappy paste applied after 3 years, it will be STUCK to the processor, think that it's still performing the job it was intended to do?
I just replaced the processor in my motherboard after 5 years of daily use, because I wanted to upgrade to a dual-core, not because of any failure, the old processor still looks brand new and works great, and the heatsink was not stuck to the processor like thermal paste will do, it slid right off and the grease was STILL in great shape and doing it's job...let me just re-state that: 5 years.
I can provide a picture of the old processor if you like, even magnified if you want so you can see there is no "mineral" damage, whatever the heck that is.
Grease is grease. Some is better than others. The stuff they foist on consumers as being "thermal paste" specifically for computers, is just plain old white lithium grease, available at your local auto parts store for a FRACTION of what you pay for "thermal paste".
Save the propaganda for the sheep brother.
