Diamond Thermal Grease Testing
 

Typical testing on a CPU platform does not control for this factor and as such, results are a mixture of the grease's thermal performance and its thickness as applied. Without compensating for the thickness of each sample, it is possible that a grease with lower thermal conductivity will perform better than one with higher thermal conductivity.

To correct for grease thickness, thermal bulk conductivity and thermal impedance, a specially designed and built calorimeter was used. This is a precise instrument that cost about $75,000 to build.

still want to see real world numbers

you know that you can scroll down on that page, right? ;p

yes, but I want the numbers in degrees

"[FONT=Arial, Sans-Serif]As a side note, this is also a very nice polishing compound!"

probably a wee bit expensive for that :P
