Measuring 74mm long, 21mm wide, and just 0.15mm thick, our graphene heat sink is specifically designed to fit this size of SSD, ensuring optimal heat dissipation and device performance. Our heat sink features a unique dual-layer design, with high-quality graphene material on one side and a layer of copper foil on the other. This combination of materials ensures efficient heat transfer away from your SSD, keeping it running cool and preventing performance degradation. Our heat sink's slim and flexible design makes it easy to install, and its compact size means it won't take up valuable space in your system. Colour:As Shown Material:Graphene + copper foil Please note: This HeatSink may be folded in the shipping process, thus resulting in surface creases, which is normal, we do not accept this as a reason for return. Laser-cut graphene hollow part of the copper foil exposed to the air, easy to oxidation and thus dark color, this is a normal phenomenon, we do not accept this as a reason for return. Due to different batches, there may be differences in product appearance and printed text, which will not affect use Package Contents: 1 * Graphene M.2 SSD Heat Sink Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
