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.

Alphacool introduces the “Core” series of high-speed fans

Six new models, with the slowest capping at 2,000 rpm and the fastest up to 4,000 rpm. It’s a mix of 120 and 140-millimeter fans, where with the larger format Alphacool reached for differently modeled rotors. This is also with a view to ensuring that a fan this fast and relatively large can operate at all at reasonably low vibration. Among Alphacool’s new products is therefore a fan with more robust blades as well. Read more “Alphacool introduces the “Core” series of high-speed fans” »

Plastic vs. metal backplate Alphacool (under LGA 1700)

For rather incomprehensible reasons, the cooling performance of the vast majority of AIO liquid coolers is degraded by the use of an unsuitable backplate. The backplate is usually undersized, made of plastic, and cannot exert optimal pressure on the processor. To give you an idea of how a “traditional” plastic backplate stacks up against a proper, steel one, we’ve prepared a comparison of the two.

Alphacool: Our new thermal paste is faster than stainless steel

Watch out, Alphacool has started aiming pretty high. In the specifications for the latest Apex thermal paste, it lists a thermal conductivity that it claims is not only above the best competing thermal pastes, but even outperforms some metals. Unless Alphacool is stretching reality, this is going to be an extremely effective formula. You won’t guess what its main ingredient is.

    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.

  3. I saw this a popular webstore where it was described as “Nickel”, as in the metal. Since Nickel dissipates heat better than Aluminum I was interested (my entire cooling loop is EK so why not one more emblem for them). I went to the EKWB website to the page for this specific passive cooler primarily to learn what the back plate was made of, I thought Acetal would be great with the Nickel top. Well, on their website they first mention that they have this in both Nickel and Black. It wasn’t until the very bottom, in fine print, that it informs you that the entire heat sink is made out of Aluminum, nickel I guess is a color here. Straps are Stainless Steel. Not the best configuration for an Aluminum block IMO, so I’m passing.

    1. Usually, when a product specifies “Nickel”, it isn’t made of actual nickel, but is merely nickel plated. It’s the same for gold and silver. You won’t find a product that states “Gold” to be actually made of gold. It’s gold plated, but not pure gold. That’s not economically viable.
