OVERCLOCKERS earlier this week tested a number of thermal pastes to see if the compounds included any silver.
The chemistry experiment was applied to Arctic Silver 5 and 3, OCZ Ultra II Premium Silver Compound and CompUSA Silver Thermal Grease.
According to the site, it's come up with some "very disturbing results" – it claims that there's no silver in the OCZ and the CompUSA greases.
But the tests show that Arctic Silver 3 and 5 did contain silver.
