Following up on our Thermal Compound Roundup - May 2011 review, we are adding five more thermal compounds to our roundup, for a total of 25 different models from Antec, Arctic Cooling, Arctic Silver, Biostar, Cooler Master, Coolink, Deepcool, Evercool, Gelid, Noctua, Prolimatech, Scythe, Shi-Etsu, Spire, Rosewill, Thermalright, Thermaltake, Titan, Tuniq, Xigmatek, and Zalman. In this review we will determine if certain products are superior to others. We will also try an "alternative" thermal compound to see if it works.
