The Thermalright Ultra-120 Extreme heatsink is a continuation of the Ultra-120 series, only with a little more muscle and a couple extra heatpipes. It's predecessor has remained at the top of Frostytech thermal test results for both AMD and Intel platforms basically since we tested it, so we're especially interested to see how the Ultra-120 Extreme model handles. Like the Ultra-120 that came before it, the Thermalright Ultra-120 Extreme applies fairly simple concepts to yield a well performing tower heatsink that doesn't have to generate much noise to get the job done.
