Cheap exotic AliXpress SSD coolers tested, some to destruction — fake heatpipes and sketchy 'graphene' deliver subpar results

Four intriguing AliExpress-sourced SSD cooling products have been put under scrutiny by overclocking pro Der8auer. Just by glancing at some of these things, many may feel doubtful about their practical use. However, it is good to get product cynicism validated by Der8auer, and also find out that some of the SSD cooling products weren’t too bad. Spoiler: some were bad, but none were great.

The test platform used to check out the quartet of AliExpress SSD coolers used a Crucial T700 PCIe Gen5 NVMe SSD (plugged in a Gen4 slot). Der8auer revealed that this SSD was happy to deliver 7 GB/s read and write speeds when sufficiently cooled. He provided some other baselines, in terms of thermals. For example, he provided read/write test thermal readings using the Asus Maximus Z790 Hero heatsink in place, and tested the system with no heatsink at all.

The first AliExpress-sourced heatsink under test was the Jui Shark M.2-Five Dual Engine. Initial impressions were that this was a practical-looking blackened-finned cooler. It was first tested without the pair of embedded active fans powered up. Running this way, Der8auer observed the SSD running at a stable 52C when idling.

Now Der8auer plugged the provided power line into the Jui Shark. Its tiny fans run at up to 8,000 RPM, so users might expect an unpleasant high-pitched noise when they are running, and this was confirmed. Though they weren’t loud fans, so the noise might not be heard if the system was encased. The Jui Shark fans were effective, with reported SSD idling temps down to 40C.

Running some read/write loads with the actively cooled Jui Shark M.2-Five Dual Engine showed it delivered a > 10C temperature delta benefit. The cooler was judged to be “definitely doing its job.” However, Der8auer criticized the cooler’s bulk and potential whiney noise profile.

The second M.2 SSD cooler under scrutiny was from FinalCool. The firm has produced a light and slim SSD cooler, though it doesn’t seem like any cooling technology is in place. It benefits from RGB, though, with a switch on the side to configure various lighting modes.

FInalCool’s product performance was ineffective, with idle temps over 70C and throttling under minor loading. Crystal Disk Mark caused the system to crash, but it ran for about 150 seconds before the blue screen of death. Der8auer recons the FinalCool heatsink might only be usable with Gen3 or Gen2  drives.

Jeyi’s M.2 Copper Graphene Heatsink is an extremely thin cooling solution, and its gumstick profile might be slimmer than a sliver of Wrigleys. The product website says it is 0.15mm thick and that it can reduce an SSD’s operating temperature by 10 degrees Celsius. Der8auer put both these claims to the test and did some close-up material inspection.

Firstly, the overclocking expert’s micrometer measurements supported the 0.15mm (0.01-inch) product thickness specification. Materials analysis confirmed copper and carbon materials were used, but it wasn’t certain whether the carbon was graphene.

Following up with performance testing, and at idle, it looks Jeyi’s SSD cooling product makes little or no difference. When Crystal Disk Mark gets powered up, thermal throttling affects performance rapidly. The system crashed before the end of the tests.

Last but not least, Der8auer looked at the iNeo (USA) M12 SSD cooler. The design raised lots of questions, but Der8auer seemed quite optimistic about this product, perhaps due to the size of this thing. In testing the iNeo performed quite similarly to the stock heatsink that came with the Asus motherboard. However, while your motherboard gains a graceful arbor, the design uses up a lot of space.

After completing tests of the iNeo’s performance, Der8auer thought it was worthwhile checking if the 2.5mm copper heatpipes were actually heatpipes and not just wires or tubes. His suspicions were correct, a quick hacksaw job revealed the “copper heatpipes” were just 2.5mm copper (plated?) wires.

Der8auer promises a follow-up video, or two, with more AliExpress oddities under his critical eye, plus some electron microscope analysis of the poor-performing Jeyi M.2 Copper Graphene Heatsink. The analysis will hopefully show whether the carbon material used was actually graphene, or not.

    Unbelievable crap .....

    These junk items are all over Amazon too.

    It might not have "real" heatpipes, but the Ineo M12 is one of the most effective SSD heatsinks on the market.

    I've tested it, if any of y'all would like to see the results:

    forgive my previous quote, i reread the review. some parts of the review, especially the conclusion is confusing, so i partially blame that for my mistake, although it is my bad for not full reading the article.

    Also while I blame poor chinese to english translation and exaggerated marketing, the graphene+copper "heatsinks" do work for a specific target market, notebooks up to gen 4 ssds with their limited space. While it does not prevent thermal throttling, it does allow the ssd to run faster for longer compared to without. I have a few of these in various laptops and I can confirm they do their job just fine.

    Note that these coolers came out before gen 5 ssds therefore not being able to cool a gen 5 ssd is understandable.

    sketchy graphene? When did he say that?

    I watched his video and he doesnt say sketchy graphene he says its impossible to tell if its graphene, graphite, or w/e with normal microscopes and he will have a future vid using an electron microscope on one.

    only thing he said was its carbon just he can't say exactly what form of carbon(due to limitations above)

    While it's not actually a heat pipe the performance on the M12 was pretty good and I think as far as the tall SSD coolers are concerned it looks good.

    deepcool and thermalright coolers are everywhere on ali express i pay with pay pal and never had an issue but by default there is bound to be rubbish products there to
