A quote from the article:
Coollaboratory Liquid Pro Reviewed
Our last product that had anything to do with heat conductivity was the Liquid Metal pads we reviewed from Coollaboratory. A super thin piece of heat conduction pad made from metal. Which indeed worked marginally better than some Arctic Silver 5, but wasn't as user friendly. The Liquid Metal pads are new, but Coollaboratory first came out a long time ago with their Liquid Pro. Liquid metal in a little syringe that should work as good, or even better than thermal paste. Let's see if this works just as good as the Liquid Metal pads.
