Final Words & Conclusion
Conclusion
The reviewed Cooler Master MA612 Stealth ARGB (single-tower) and MA624 Stealth (dual-tower) coolers performed well and handled both tested processors, including the Core i9 10850K at 5.1 GHz. The smaller one uses a dual pack of 120 mm fans, the bigger – two 140 mm. Both are reasonably quiet. It’s possible to set an even less noisy fan curve– silence is always desired, especially if your CPU is not a high-end model. For the MA624 Stealth, you can change one 140 mm fan to a smaller one (bundled), but that doesn’t bring any visible performance or noise difference. It’s rather to get more RAM compatibility.
Aesthetics, Design & Installation
Starting with the aesthetics, the Cooler Master MA612 Stealth ARGB and MA624 Stealth look very good. You won’t find any LEDs in the bigger cooler, and if you need those – you can choose the single-tower solution. The black colour scheme makes the blending of this cooler into the system easy. The surface is quite scratch-resistant, so the paint should last enough. The installation process is relatively easy (but strange for the AM4 system, you need to remove the stock backplate). One great thing is the fan "clips" are made of plastic, and it's really easy to mount it on the radiator. Nice solution! The Cooler Master MA612 Stealth ARGB is not so great in size, but the MA624 Stealth is (especially when you’d like to use the standard set of two 140 mm fans and then install 40 mm memories. The weight is under 1 kg for the single-tower solution, but the dual-tower is 1.6 kg. For me – it would be quite worrying about the motherboard flex. Also - The ARGB cables themselves are a bit too short in the MA612 Stealth ARGB.
The Verdict
The Cooler Master MA612 Stealth ARGB and MA624 Stealth are not cheap at all. The first one costs about 90 EUR, the second – 100 EUR. Well, performance is nice in both cases, the noise is also very reasonable. The looks are really, really nice; the black should suit most of the systems. The dual-tower solution is good when you don’t like the bling-bling (I mean the ARGB); the single-tower on the side should satisfy the users that want some colours (additionally, you get the controller for this feature, if you don’t connect to the motherboard). The MA612 Stealth ARGB offers perfect RAM compatibility due to the radiator design; for the MA624 Stealth, it’s not so obvious due to the overall size of the cooler. Suppose you want to have the possibility to install 40 mm memory. In that case, you need to either remove one 140 mm fan, replace it with the provided 120 mm version or… mount it higher, but this will make the cooler taller (almost 17.4 cm, which can be problematic for many chassis). The weight of both coolers is above 1 kg; the single-tower is 1.2 kg, dual-tower is over 1.6 kg. That’s massive and makes you wonder if the motherboard will survive it in the long term. Additionally, it’s a bit strange that Cooler Master didn’t use the standard backplate for the AM4 platform. But maybe it was deeply thought, I’m not an engineer. Also - the ARGB cables themselves are a bit too short. One great solution (regarding the installation) is that the fan clips are made of plastic, and it's easy to attach them to the radiator. So summing it up – it’s hard to say anything bad about those two coolers, other than that the price is too steep. For this combination of looks/features and especially performance/noise ratio, we think that the “Recommended” award is justified for both of thee products. If the price would be lower by 20 EUR for each cooler, then it would be a must-have, but there are many alternatives at the current status, and even some of the AIOs are cheaper than the CM solutions. You need to check the dimensions, think about your needs, and choose the best option for you.
