M.2 SSD heatsinks are small metal coolers that attach to an M.2 NVMe drive to help it avoid throttling under sustained load. They suit desktop builders, workstation owners and anyone fitting a fast SSD to a board without its own cooling. Our range is small and includes models from ICY BOX, Supermicro, be quiet! and AKASA.
How to choose an M.2 SSD heatsink
Drive and slot fit. Most desktop M.2 drives are 2280 (22 mm wide, 80 mm long), but shorter and longer sizes exist, so check the lengths a heatsink supports. Look at whether your drive has memory chips on one side or both, because a heatsink that covers only the top will leave the underside uncooled.
Clearance. Height decides whether the heatsink fits at all. On many motherboards the M.2 slot sits directly beneath the graphics card or close to the CPU cooler, so measure the free space before you buy.
Material and cooling design. Aluminium is the usual choice because it is light and spreads heat well. Copper conducts heat better but weighs more, and both materials appear in our range. Fins add surface area, and a passive block is silent, while a fan-assisted model moves more air if the case has poor airflow.
Mounting method. The heatsink must press firmly against the drive through a thermal pad, held by clips, screws or a clamp. Check that the fixing suits your slot, and remember that a heatsink already built into your motherboard usually has to be removed first.
Finish. Colour has no effect on cooling. It only matters in a case with a window, where the heatsink is visible. Our range includes black and silver models.
M.2 SSD heatsink brands we carry
- ICY BOX: known for storage accessories such as drive enclosures, docking stations and mounting frames, so its heatsinks come from a company that focuses on drives.
- Supermicro: a maker of server and workstation hardware, which makes its cooling parts relevant to systems built for continuous operation.
- be quiet!: a German brand best known for low-noise CPU coolers, fans and power supplies, with a focus on keeping PCs quiet.
- AKASA: specialises in thermal products such as passive and fan-based coolers, including parts for small form factor systems.
M.2 SSD heatsink FAQ
Do M.2 SSDs need a heatsink?
Not always, but fast NVMe drives benefit from one. They can slow themselves down when they overheat during long file transfers or heavy workloads. For light everyday use, the drive may run fine without extra cooling, especially if the motherboard already includes a cover.
Is an aluminium or copper M.2 heatsink better?
Copper moves heat away from the drive more effectively, while aluminium is lighter and is enough for most builds. The fin design and the airflow in your case often make as much difference as the metal. If space is tight, check the weight and height as well as the material.
Can I fit an M.2 heatsink in a laptop?
Usually not, because most laptops have very little room above the SSD. A desktop heatsink can be too tall or too wide for the chassis. Check the free space and your laptop maker's guidance before trying to fit one.
How do I install an M.2 SSD heatsink?
Fit the drive into its slot, remove the protective film from the thermal pad and attach the heatsink with its clips or screws. The pad must make full contact with the drive's chips. Take off any existing motherboard cover first, and switch off and unplug the PC before you start.
