Before the instructions were finalized (or in the form they're in now, I suppose they'll always be changing as they learn more about the enthusiast community and all the complications it brings)....I tried reflow overclocked and overvolted. Unplugged the pump and instant lock-up. Tried again at stock speeds and overvolted, therm-trip kicked in about 3 seconds (~125C...what it does when even throttling won't work) and rebooted the system. In an overclocked system with a pump failure, I really wouldn't worry about the TIM melting again...you'll have incredible instability or hit thermtrip before it gets a chance to melt and drip. Down at stock speeds though, that's another story.

As for how it does subzero, I've been talking to Enerdyne about it and they're curious about it as well...that's how I know it'll be tested really cold soon enough
