Those tests are total garbage he had room temps from 12c ~ 26c.
Look at the chart yourself henydiah, you've recommended this same review many times.
Check the link in my sig. all the tests were run at 23c ambient room temperature, under the exact same circumstances, each thermal compound was tested under the exact same clamping pressure, same room temperature, they all were fairly evaluated.
How could anyone claim any type of fairness in a testing review with room temperature differences that great?
As well known as you are here, how could you recommend that review?
At least read what you're recommending.
