The MasterAir MA824 Stealth features a nickel-plated copper base that makes direct contact with the processor, transferring heat through eight composite copper heat pipes to the dual-tower heatsinks. This cooler has two more of his heatpipes than the previous MasterAir MA624 Stealth and Noctua NH-D15. Compared to the MasterAir MA624 Stealth, Cooler Master has revised the fin stack design and thickness of the MasterAir MA824 Stealth for better thermal performance. Cooler Master showed the MasterAir MA824 Stealth at Computex 2023, and the cooler had a temperature sensitive coating. Basically, heatpipes and heatsinks turn red when heat dissipation is working. It’s a shame this great feature didn’t make it into the retail product.

The MasterAir MA824 is compatible with tall memory modules despite its large heatsink. The default configuration has 1.7 inches of clearance space and a single fan configuration has a maximum of 2.6 inches of clearance. The MasterAir MA824 is more roomy than the Noctua NH-D15, offering 1.3″ and 2.5″ of clearance in default and single fan mode respectively. The MasterAir MA824 Stealth is compatible with many newer and older sockets. Supports Intel’s LGA1700, LGA1200, LGA115x, and AM4 and AM5 sockets.

Cooler Master equips the MasterAir MA824 Stealth with two Mobius cooling fans with loop dynamic bearings. The vendor staggered a pair of her PWM cooling fans to maximize push-pull performance. The consumer can add a third fan of his of choice. The central fan is a Mobius 135 (135mm) that delivers up to 1.92 mmH₂O static pressure with a maximum noise level of 24.6 dB(A). while the other is the Mobius 120 (120mm) rated at 22.6 and 2.69 mmH₂O. dB(A). The MasterAir MA824 Stealth 30th Anniversary Edition features a 120mm fan with brilliant ARGB lighting. In theory, Cooler Master’s Mobius fan seems to outperform Noctua’s NF-A15 PWM 140mm fan cooling the NH-D15. The static pressure of the NF-A15 PWM fan is 19.2 dB(A) at 1.51 mmH₂O. The NF-A15 PWM does not perform as well as the Cooler Master fan, but is significantly quieter during operation. Cooler Master rates the MasterAir MA824 Stealth’s cooling capacity at up to 250 watts with a dual fan layout.

The MasterAir MA824 Stealth comes with a 5 year warranty. Cooler Master has not disclosed US pricing or availability of the MasterAir MA824 Stealth or MasterAir MA824 Stealth 30th Anniversary Edition. The cooler is already available in the UK with a MSRP of £99.99 (approximately $125).
