BenchmarkReviews.com 80-product review rated Alumina in the Good class, with a B+ "enthusiast grade"; it cooled a test system 10% better than the last-place finisher. Céramique Céramique is a composite of boron nitride, aluminum oxide, and zinc oxide. All of these are ceramic substances, that is they have crystalline molecular structures. Céramique's suspension fluid is a polysynthetic oil base. It is an electrical insulator, which makes it a better choice than pastes that contain metal (such as AS-5) when there is a possibility that the thermal compound could come in contact with the pins of an integrated circuit: for example, exposed resistors on the tops of some chip packages or a tightly packed circuit board or expansion card. The 2009 BenchmarkReviews.com 80-product review rated Céramique in the Good class, with a B+ rating; it cooled a test system 10% better than the last-place finisher.
