Today’s review is more of a comparison than a true review – we are comparing three of Thermalright’s top-of-the-line CPU heatsinks in passive, pseudo-passive, and active cooling modes. Our three contenders include the Thermalright HR-01, the XP-120, and the Ultra-120. What we really want to find out is how the HR-01, which is designed for passive cooling, compares to the XP-120 and Ultra-120, which rely on active cooling with a fan. The HR-01 will be tested with, and without, a Thermalright 120mm Fan Duct. All testing was performed on an Intel P4 Extreme Edition dual core 955 CPU heater inside a closed mid-tower case.
