JEYI M.2 2280 SSD Heatsink, Graphene+Copper Foil, 0.5mm Ultra-Thin, 1500W/mK Thermal Conductivity, for NVMe/SATA SSDs (5pcs)

Easy to work with

I used this on 11 NVME 2280 ssd’s spread across 4 different pc’s and saw a grand total of 0 degrees in temp drop. Not a single drive saw any performance improvement I followed the installation instructions in the product listing and they adhere very well to the drive but it didn’t make a bit of difference in idle temps or under load temps. It’s a complete waste of money.

Love these

It is less adhesive grip once you unpeel while re-aligning 2nd or 3rd attempt. Copper sheet is little on the stiff side so if your nvme chips surface height are uneven there will air gaps rendering this a functionless heatsink. If Jeyi make the adhesive strength a little stronger, this is a great way to use in tight spaces such as Minisforum MS-A2 mini workstations and others alike

I'll happily change that low score if anybody can explain to me how a "graphene+copper foil" heatsink (of any thickness) can be electrically non-conductive. Both graphene and copper conduct electricity, and do so rather well (low resistance). Graphene's property as an excellent conductor of electricity is a key reason why thermal pads made from graphene can be tricky to use. So, either this product isn't made with graphene, or its description as electrically non-conductive is wrong. Neither of which is a good thing.

I first used them on 4tb WD black nvme and was hoping to also add an thermalright nvme cooler for extra effect, turns out the nvme cooler would not attach with this JEYI attached (too thick). so trying to remove it basically destroyed it; all wrinkled and bent. and that's when i realized these spreaders are use once then throw away, i managed to iron it out flat and attach it on the back of my graphics card for extra cooling but these spreaders at best, can be reused maybe 1 to 2 times before their trash. i tend to use old nvme coolers as chipset coolers so not being able to reuse them keeps me from buying more in the future
