This is the first liquid-metal based cooler so we're not sure what to expect, but according to Danamics this cooler will put most watercooling setups to shame:
If you're wondering what all the fuss is about, the LM10 has no moving parts and an unlimited mean time between failures. Inside is a yet-to-be-named liquid metal that's said to provide superior thermo physical properties and is circulated without moving parts thanks to a built-in electromagnetic pump.
The promise is lower thermal resistance than any air-cooler and cooling performance that'll put most water-cooled setups to shame. That's still the claim, but we've yet to see any real-world performance figures and although we have a launch date, we're still missing the key ingredient; pricing.
