Overclockers.com recently conducted a test of popular Thermal Paste compounds indluding: Arctic Silver 5, Arctic Silver 3, OCZ Ultra II Premium Silver Compound, and CompUSA Silver Thermal Grease. To their surprise, only two of the four products actually had some silver on them, while the remaining pair had none at all! Isn't that what you can call misleading?
In response to this article, OCZ has issued a recall of their product claiming they "do not manufacture Ultra 2 thermal compound in house, it is provided by a foreign manufacturer".
