Thermal Compound Roundup – December 2011

Introduction

Following up on our Thermal Compound Roundup – November 2011 review, we are adding five more thermal compounds to our roundup, for a total of 55 different models from Akasa, Antec, Arctic Cooling, Arctic Silver, Biostar, Coollaboratory, Cooler Master, Coolink, Deepcool, Dow Corning, Enermax, Evercool, EVGA, Gelid, Glacialstars, Innovation Cooling, Masscool, Nanoxia, Nexus, Noctua, Phobya, Prolimatech, Scythe, Shin-Etsu, Spire, StarTech, Revoltec, Rosewill, Thermalright, Thermaltake, TIM Consultants, Titan, Tuniq, Xigmatek, Zalman, and ZEROtherm. In this review, we will determine if certain products are superior to others. We will also try another “bread topping” thermal compound to see if it works.

For a better understanding of how 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 and our article What is the Best Way to Apply Thermal Grease? 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 raising it.

Figure 1 shows the five new thermal compounds that we are adding to our roundup.
