Following up on our Thermal Compound Roundup – February 2011 and Thermal Compound Roundup – March 2011 reviews, we are adding five more thermal compounds to our roundup for a total of 15 different models from Antec, Arctic Silver, Biostar, Cooler Master, Coolink, Deepcool, Evercool, Gelid, Noctua, Prolimatech, Spire, Thermalright, Xigmatek, and Zalman. In this review we will see if certain products are superior to others.
For a better understanding of how the thermal compound (a.k.a. thermal grease or thermal paste) works and how to correctly apply it, please read our How to Correctly Apply Thermal Grease tutorial. The most important concept that you must understand is that it is a mistake to think that the more thermal grease you apply, the better. The thermal compound is a worse heat conductor than copper and aluminum (the metals usually found on cooler bases). So, if you apply more thermal compound than necessary it will actually lower the cooling performance instead of improving it.
In Figure 1, you see the five new thermal compounds we are adding to our roundup.
Let’s get a closer look at the new contenders in the next pages.
