Duel of SSD coolers: Alphacool HDX M.2 vs. EKWB EK-M.2

Results: cooling of the controller and memory

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.

Test of 27 thermal compounds, part 1

Thermal pastes can significantly affect the cooling performance, so we have compared several models that represent the current offer. Is the legendary Arctic MX-2 still a good choice? Or is it more reasonable to try newer Cooler Master and Cryorig? There is also a copper Coollaboratory to consider. Well, we have prepared some recommendations, but few warnings too because there are several products that you should rather avoid. Read more “Test of 27 thermal compounds, part 1” »

    1. Not sure but i did use 3 on my GODLIKE MB and i have a close friend that did use them on his Maximus XI EXTREME

  1. The reason that the Alphacool did not properly cool the memory but cooled the controller a bit is because the controller gets hotter than the memory and because it is technically a ‘heat spreader’ not a ‘heat sink’ it was spreading the heat from the controller to the memory since they are all connected thermally & the ‘heat spreader’ is not thick enough & having fins/ribs etc. to properly sink the heat away.

  2. I have a Z390 Auros Extreme, and it has the same heat sink setup as the Ultra which I also have. I was concerned with the high temps with the beefy heatsinks both bords have, so I tried the EKWB. The results are very close to the same as the stock heat sink. The only real cure is massive airflow. I’ll be waiting for a reputable MFG to come up with an active cooler, shouldn’t be hard, similar to memory cooler. Currently, I just have a small 80mm fan sitting on my GPU backplate doing the job, but it’s kind of a hokey setup for $6K rig.
