Cooler Master is synonymous with mainstream cooling products, from heat pipe air towers to high-performance liquid cooling AIOs, many of which focus on RGB lighting. However, the large dual-fan MasterAir MA624 Stealth is ready to impress people without any lighting decoration. Instead, it uses an all-black color scheme to create a majestic look for those who prefer the appearance without flash. It also takes advantage of some smart integrated installations and includes a third (extra!) 120mm fan to provide greater flexibility for systems with high memory DIMMs.
Cooler Master MasterAir MA624 Stealth strikes an attractive balance between heat dissipation and aesthetics. It is a sharp performer.

Cooler Master’s MasterAir MA624 Stealth comes with a healthy installation kit, which supports almost all current Intel and AMD desktop processors-except Threadripper chips. Installation hardware includes electroplated brackets, brackets and tension screws, as well as universal backplanes. A small tube of MasterGel is equipped with a universal Phillips screwdriver and 2-way PWM fan distributor.
Cooler Master provides a 5-year warranty for MasterAir MA624 Stealth.
The MasterAir MA624 Stealth uses 6 copper heat pipes from the bottom up through a pair of heat sink fin sets that span an integrated 140mm SickleFlow fan under the brushed aluminum top. A pair of spring tensioned mounting bolts extend from the top of the cooler down through the base to fix the cooler on the cross bracket of the motherboard.
The Cooler Master includes a pair of 140mm SickleFlow fans (center + front) and an additional 120mm for backup settings. This allows the MA624 Stealth to be used as a silent single fan (center) setting for maximum memory clearance, or to operate in a push-pull standard installation using 140mm front-mounted SickleFlow fans.
Replacing the buckle bracket with an additional 120mm SickleFlow fan allows for better memory clearance while still allowing push and pull settings. Additional 120mm or 140mm fans can be used for push+pull+pull cooler settings (with additional fan brackets), or as a chassis fan for airflow elsewhere.
Cooler Master sets the speed of the 140mm fan at 1400 RPM, while the speed of the 120mm fan is expected to reach 1800 RPM.
The base of the Cooler Master MasterAir MA624 Stealth clamps all six copper heat pipes between the mounting block and the 40mm x 40mm milled cooler cold plate.
The cold plate was ground flat, and any signs of background lighting between the cooler and our steel ruler were zero.
From this view, the integrated mounting arms and spring tension screws can be easily seen, while the centrally mounted 140mm SickleFlow fan falls into the clever notch carved into the mounting system.
The uniform tension allows the thermal compound to be evenly distributed, compressing and dispersing our Arctic MX-4 application during the installation process.
Installing the Cooler Master MasterAir MA624 Stealth is relatively simple: After fixing the backplane or a proper offset, place the motherboard on it crosswise, and then tighten it in place. The pair of vertical spring tension screws are aligned on the cross bracket, and the cross bracket is directly aligned with the threaded hole below. A single fan (center installation) is complete, or the front 140mm (or 120mm) can be clipped to the front of MA624 Stealth to complete the standard push-pull installation.
