'I decided to test Arctic Silver 5, Arctic Silver 3, OCZ Ultra II Premium Silver Compound, and CompUSA Silver Thermal Grease. This test was not conducted to test performance, but rather to determine if these compounds have Silver as an ingredient.' Using a professionally mixed testing solution, they found that several brands do not, in fact, contain any silver at all! So, are you getting what you are paying for?"
