Review: Cooler Master MA824 Stealth


AMD CPU temperatures

Processor at 65W :

We start with our 65W profile, a fairly low power consumption, especially when you consider today’s monsters. This power consumption is intended to simulate small processors with few cores or low power consumption.

Under these conditions, Cooler Master’s heatsink is already positioned at the top end of the market. Here, it’s in the same category as Noctua’s NH-U12A, with similar temperatures. It will do slightly better at full throttle and a little less well at low revs. In any case, we feel it’s in a completely different league to the Jonsbo, DeepCool and NZXT fans.

CPU at 100W :

Here, our CPU will run at 3.30 GHz constantly and on all its cores. We apply a VCore of 1.132 to obtain a power consumption of around 100 watts. To simplify reading the graph, we’ve rounded off some values to the nearest integer.

At 100W, we again find a result very similar to that of the “little” Austrian NH-U12A. This time, at all fan speeds, the two products are neck and neck. In any case, the competition has been left behind!

Processor at 150W :

Finally, we end with our 150W profile. Here, heat dissipation is higher, so let’s see how our coolings fare!

In the end, being big isn’t all bad news (not to be taken out of context, we trust you). The imposing size of Cooler Master’s cooler gives it the edge over its rival Noctua on our 150W profile. In these conditions, it does better in 12V and 8V. In 5V, however, it beats the NH-U12A by a narrow margin.


The temperatures obtained with this heatsink are therefore very good. Moreover, we feel it’s possible to do better, as a single-tower 120mm model rivals this MA824 Stealth. Admittedly, it’s not just any cooler, but given its size, we were expecting a little more. Let’s see how it performs on Intel processors. But we’ll look at that after the temperature-to-noise ratio on AMD platforms!
