The MasterAir Pro 4 CPU Cooler from Cooler Master cools an AMD or Intel processor with an air cooled design that consists of an aluminum heatsink, a 120mm fan, and four copper heat pipes. The PWM fan spins at a variable rate between 650 to 2000 rpm and is mounted to the heatsink via a fan bracket. This air cooler is built with a Continuous Direct Contact Technology 2.0 design that places the copper heatpipes closely together, increasing the contact area with your processor by 45%, to dissipate heat better than previous generations of coolers. In addition, Cooler Master includes an X-bracket kit and a push-pin bracket so you can easily install the MasterAir Pro 4 to various CPU socket types.
Continuous Direct Contact Technology 2.0 has an increased surface of 45% over previous versions by compressing heatpipes together, helping to dissipate heat more efficiently
One 120mm fan, 4 heatpipes, and stacked aluminum fins allow cooler air into the heatsink while steering extra ventilation to hotspots
Upgrading and removing MasterFans are a breeze with an intuitive fan bracket design
Installation is made easier with a sturdy X-bracket or a push-pin bracket, which lets you use your fingers to pin this cooler to the motherboard
