The PC cooling market is more than crowded with models of all sizes, shapes, and colors, so it’s pretty hard to stand out in one area or another. Cooler Master MasterAir MA624 Stealth aims to enter the high end directly based on brute force, since we are faced with a huge heat sink (measuring 144.9 x 153.2 x 160 mm) that integrates no less than three factories Fans .
MasterAir MA624 Stealth, performance and silence
As we said, the radiator includes no less than three factory fans, two of which are 140mm (SickleFlow) and the third one is 120mm, which is smaller than the other two to interfere with the large modules less. RAM memory. As with Noctua’s high-end heatsinks like the NH-D15, the fan on the right side can be flipped up to avoid interfering with any type of RAM.
It has two blocks of aluminum sheets linked together by six nickel-plated copper heat pipes 6 mm thick, with a fan on each side and another in the center. According to the manufacturer, this radiator can only work perfectly with the fan in the center to have a much smaller size and, at the same time, much quieter.
Each 140mm SickleFlow fan spins at 650-1400 RPM, pushing up to 67 CFM of air and emitting a maximum of 27 dBA of noise. The 120mm model runs up to a speed of 1800RPM, moving an airflow of 62 CFM and also emitting 27dBA of noise, so even with the three fan configuration, this Cooler Master radiator is quite quiet.
The six heat pipes converge from the base, welded to them, so it does not use direct contact technology. As you can see in the pictures, the upper part is covered with a screwed aluminum block, brushed in black.
The heat sink is compatible with all modern processor media except the TR4, including Intel LGA1200, LGA2066, and AMD AM4. Of course, if you enjoyed reading this and want to buy it, you should take into account its huge dimensions, so we recommend that you check that it fits in your box without problems, because as they say it is enough large (it measures 144.9 x 153.2 x 160 mm; in comparison, a Noctua NH-D15 measures 161 x 150 x 165 mm).
Price and availability
For now the Cooler Master MasterAir MA624 Stealth is not even listed on the manufacturer’s website, but it has appeared in some online stores in Hong Kong at a price of 785 HKD, or around 83 dollars. If we take this into account, there are numerous ballots indicating that when the heater hits stores in Europe in the coming weeks, it will be priced up by taxes, so it wouldn’t be surprising if we saw it. in stores at a price close to 100 or even 110 dollars.
