The Arctic Cooling High Performance MX-2 Thermal Compound was the best compound from the lot that I tested - but not by much. It beat out the Arctic Cooling Ceramique thermal compound by a few degrees in some tests, especially under load. It's good to see a compound that can keep your computer cooler when it's under load because that's what really matters. Thirty five degrees Celsius at stock while idle is close to the best that I've seen. That's definitely a good temperature to be at for stock idle.
