M.2 SSD Heatsink

I have an MVNe with no heatsink on the motherboard, so this heatsink does the job. No problems at all. Easy to install

I have a BMax mini pc with almost no room for a M.2 2280 heatsink. Being so compact, there is almost no airflow despite all the fans being in perfect working order. My CPU was running on average at 78°C, with highs at about 88°C. My WD Blue M.2 SATA 2TB drive is right next to the CPU, and was running on average at 72°C, with highs at about 86°C. After installing this little heatsink, the drive runs on average at 56°C, while the CPU stays unchanged of course. This is probably the most effective slim heatsink I have ever tried. The little rubber rings are a bit difficult to handle, but they give you an alternative with the fabric straps, and those work well. Though, you get better contact and heat transfer with the rubber rings. Overall, a good design for difficult form factors.

Looks nice, functions well. Only issue is that the O rings break apart fairly quickly. I had to use a different set of rings from another product.

These heat-sinks are nearly perfect for my needs. I have several OWC Express 4M2 4-Slot M.2 NVMe SSD Thunderbolt Enclosure's and each one holds 4 drives. I try to get drives that have no heat-sink or have a really small one because many drives come with one that is too large and there is very little room between the chip and the intake fan in these things as you can see from the pictures. I could go with the cheap and simple copper plates, but I wanted something with fins to help pull the heat away when the air blows across it from the fan. As you can see, these fit perfectly and still allow a bit of room for air to move around from the fan.My only complaint has to be the rubber bands they come with. First, they are super hard to get on. You need to be careful not to damage the chip while trying to attach them. Once their on, they feel very secure, but the 2nd problem comes later. The heat from the chips and the sharp edges eventually make the rubber bands break. All the ones I applied to the chips that used these heat-sinks broke, so I used the long adhesive straps that also came with it and those seem to work much better so far. Otherwise everything is perfect so far. I cant really tell if they help with keeping the temps down or not since the software running the raid does not let me monitor the temps, but I'm sure they have to be helping.

This is well made and works as one would expect, but I have no idea why the o-rings are super fragile.I don't even use a hot running m.2 with this heat stink.I ended up using the two straps to hold it on, which I should done in the first place.

Works well

I have an 8TB WD SN850X I bought for my new GPD Win Mini 2025. The device doesn't have the best cooling, with cramped internal space. The SN850X got consistently hot enough it was reaching high-70 degrees, and occasionally the 80 degree limit, when under load. I put this thing on the drive and it seems to have reduced the temperature under load by about 10 degrees, with it hovering in the high-60s and occasionally reaching 70 degrees.As others have mentioned, the black silicone o-ring is garbage. But there are two other things you can use to strap the heatsink to the SSD.

I have a few of these and they work well and are not to difficult to install
