With increasing IOPS, SSD cooling demands also increase. This applies even to powerful models (NVMe) for common customers. In most cases, controllers can take a lot, but high temperatures do not add to their performance nor lifespan and they can cause problems even in very quiet computers or in a room with higher air temperature. An additional heatsink can do wonders.
The influence of the heatsink on SSD temperatures is crucial. Alphacool HDX M.2 reduced the controller temperatures by more than 20 °C (from 86.6 to 64.7 °C). However, when it comes to memory, it has the opposite effect – the results are better without the cooler.
Heat transfer from the heatsink could be more efficient, it is limited by the absence of ribbing. But we cannot say that it is something dramatic. Compatibility is also worse, for many boards it is just too thick sandwich. We do not understand why are both parts of the heatsink same when the cooling demands of each side are significantly different.
EKWB EK-M.2 is simply an excellent product. It leads by 7 °C (with more powerful SSD it could be even more), and it cools the memory too. Also, (dis)assembly is really handy. A great effective supplement for a reasonable price (10 €).
It is quite difficult to find any negatives here. We found one though. With a “double-sided” SSD, there might be collisions with space under the M2 slot. However, this needs to be resolved by motherboard manufacturers rather than EKWB. They did everything in order to avoid incompatibility. In their official support list, they even recommend using a SSD with chips on one side only (probably as a prevention).
