EK Water Blocks EK-M.2 NVMe Heatsink Hard drive Heatsink

The heatsink nicely fit with Samsung EVO 250GB (Samsung (MZ-V6E250BW) 250GB EVO PCI Express 3.0 x4 NVMe Solid State Drive). I have pealed the paper stickers and left the copper plate at the back of the drive. Just make sure, you the stand of of the socket fits in the cut off of the heat sink back plate.The drive on its own, Even plugged in without any partition at idle, the controller runs at 50C (nvme-cli in linux) and it is indeed hot on touching. Running a benchmark in gnome-disk utility peaked the temp of the controller over 70C immediately. Attaching a heat sink did helped (stripped stickers from the drive), it is in middle 30s on idle and the heat up under load is at least slowed down. It took some minutes to warm up to about 60C. There was no direct air flow on the heatsink while testing and the case was opened for finger-touch-temp tests :-) I think, in normal operation, you probably don't stress the drive for that long period to warm up, so the heat sinks helps.And it looks cool on a black motherboard :-)

Easy to fit onto 970 evo plus 250GB, dropped temps by around 10 Celsius.

Nowhere does it warn of this but it is for m.2 units with modules on ONE SIDE ONLY! Larger capacity storage 4TB+ will likely not be compatible. They look great, are fiddly to fit and DO (or at least should) come with thermal pads. They lose serious points though for being for single sided m.2s only.

My Samsung 970 Pro M2 was idle at 60C and under load sometimes 70-75C. I bought this, easy installation but remember this because you will find it difficult to close the clips. On a 970 Pro use the 0.5 pad for the two large chips and 1.0 for the other end of the SSD, the two chips are higher than the rest, and use the 0.5 on the bottom and it will clip together easily and completely level.Now idle at 47C and under full load never exceeds 55C.Excellent product, and looks pretty good too!

Works as advertised and looks a lot better than having an ugly green pcb on my beautiful black motherboard. Fitting was easy with my Toshiba XG3 512Gb SSD as it's single sided, do not attempt to use this with double sided!

-10 degrees Celsius, stable at 50c full load

Good heatsink, a little basic for the money its a £4-£9 product really but at least your getting a product from a good company not a cheep part that come with faults that kills your m.2.Note the one star review from UK Dan which warns of the issues with back mounted low profile M.2 sockets, you should not use this with any M.2 socket which doesn't have at least 4.2mm clearance between the board and the m.2 drive when mounted, otherwise the retention clips on the heatsink will touch the board (possible short/damage to m.2 socket), bend the M.2 and separate from some of the IC's on the M.2 disk.I have these installed on:Samsung SM951 (128/256/512gb)Samsung SM961 (512gb/1tb)Samsung 950 and 960 Pro'sThe heatsinks improve all of them, with a lot of disk to disk use these devices can throttle when in areas where there isn't a lot of cold air coming into them as the controller IC has a small footprint and overheats quite quickly under load (reasonable when you think that enterprise Sans cant move this much data around that fast). When these are installed and there is reasonable air movement you can bring the temperature down by 30+ degrees (100 degrees to 60 is common in some of the systems) this will speed up the transfers and the lack of heat will also lengthen the life of the IC's.I have noticed that the IC's can come away from the heatsink and thermal pad at times, this is when there are chips with different heights across the board e.g SM961 1tb which is tallest on the 2x flash chips low in the middle and then in between height at the controller chip at the connection end of the card. This I have found means that on first fitting the heatsink had almost no pressure on the last flash chip or the middle of the card. If you have this issue use the provided thermal pads to compensate so I fitted a piece of the thin pad to the back and flash chips, some of the thicker one to the controller, and a mix of both to the middle, the level of the chips are now flat as seen by the heatsink, and there is no gap now at the flash end of the card the reason btw for fitting the thicker one to the back, is that with out that the overall size isn't thick enough to engage the heatsink properly under pressure, and there is no point is fitting this with air gaps or loosely.4 start only for cost, it is a good product and if you have no heatsink on your m.2 but read and write to it a lot and your slot allows this, its a good purchase I would recommend to anyone.

Tried to install onto the KC3000, clips are to short to use with this drive to hold the heatsink on, it's a shame varied size of clips or some other mechanism isn't used to counter this problem.Was hoping the adhesive on the thermal pads were strong enough to keep the heatsink on alone, but sadly not.Turned into a paperweight, I could try a smidgen of glue at each end of the thermal pad to hold the heatsink on and keep it off the pcb so can easily be peeled off is a solution I'm toying with.
