Cooler Master MasterAir Pro 4 & MasterAir Pro 3 Overview
The MasterAir Pro 4 and MasterAir Pro 3 CPU Coolers are very similar with only a few key differences. So as you can guess the MasterAir Pro 4 is the larger of the two coolers with official dimensions of 84x129x158.5mm (LxWxH). The MasterAir Pro 3 is only slightly smaller at 61.5x108x140mm (LxWxH). Cooler Master has different applications in mind for each cooler. The MasterAir Pro 4 is to be used in mid tower and full tower builds whereas the MasterAir Pro 3 is for smaller builds.
Both coolers feature Cooler Master’s own MasterFan Pro Air Balance fans. The Pro 4 has a 120 mm version while the Pro 3 has a 92 mm version. Cooler Master says these fans give users the perfect amount of flow and balance. These fans has a dust-proof design and should run pretty quiet. Cooler Master has outfitted each cooler with a new intuitive fan bracket design which makes installing and upgrading as easy as possible. The bracket is made of plastic and mounts either on the front or back of the cooler, no more flimsy fan clips! It supports all fans from Cooler Master’s MasterFan Pro Series. Anti-vibration pads are built into the bracket as well so that will cut down on noise.
Behind each fan you have a aluminum stacked fin array heatsink. The MasterPro Air 4 is 18.5 mm higher so its heatsink is slightly larger. Each heatsink fin has X-vents and an air-guide to steer extra ventilation to the hottest spots of the cooler. If we take a look at the coolers from the side we can see they are not all that thick it all, again the MasterAir Pro 4 is slightly thicker. This should mean we will not run into any clearance issues with RAM or surrounding components on our motherboard.
You can see that the heatpipes coming from the base of the cooler go up into the heatsink in a “U” shape. They protrude out the top of the cooler. The top fin of each cooler is painted black and has the Cooler Master logo on it. This is of course what will show out if you have a window in your case.
Taking a closer look at the heatpipes the MasterAir Pro 4 features 4 copper heatpipes whereas the MasterAir Pro 3 has three. These heatpipes are fused into the base of the cooler and will make direct contact with your CPU. Some say that this makes for better heat transfer than a solid heatsink base. Cooler Master uses their new Continuous Direct Contact 2.0 technology which compresses the heatpipes together and provides 45% more surface area on the cooler base which improves heat dissipation compared to the previous version (CDC 1.0).
