- Three rubber rings secure heatsink without tools
- Copper outperforms 237W/mk aluminium for faster heat transfer
Copper heatsink for M.2 2280 SSDs
This pure copper heatsink measures 70x20x2.5mm and includes a thermal pad plus three rubber rings for mounting. It fits NVMe and NGFF drives in the 2280 form factor such as the 970 EVO, 960 PRO and similar models. The slim 2.5mm profile suits laptops and other tight spaces where clearance is limited.
Sustained thermal transfer
Copper conducts heat at 401W/mk, well above the 237W/mk of aluminium, so the fin array pulls energy from the controller and NAND continuously during long writes. The thermal pad fills microscopic gaps between the drive and the heatsink, maintaining consistent contact pressure through the rubber rings. This combination keeps temperatures stable rather than letting them climb after the first burst.
Passive operation in confined builds
With no moving parts the heatsink adds zero noise and draws no power, relying on natural convection across its exposed surface area. The thin profile allows it to slip under motherboard shields or inside slim chassis without blocking adjacent slots. Installers should verify the controller area matches the 70x20mm footprint before fitting.

Questions about this item
How hot does the 401W/mk copper heatsink get during all-day NVMe workloads?
The 70x20x2.5mm pure copper spreader (401W/mk) draws heat from the SSD into the air through its fins; no fan is included, so temperatures depend on case airflow.
What mounting hardware must I already have to install the 70x20mm heatsink?
The kit includes one thermal pad and three rubber rings; you only need a compatible 2280 NVMe SSD and a screwdriver if your motherboard uses a screw instead of a clip.
Will the 2.5mm profile fit alongside my older 850 EVO and 960 PRO drives in a tight laptop?
Yes — the 2.5mm thickness clears most laptop M.2 slots, and the 70x20mm footprint matches the controller area on 850 EVO, 960 PRO and other listed 2280 models.
