EN-Labs M.2 2280 Pure Copper Heatsink 70x20x4.0mm diy cooling

SKU CH-BJ4M-J1AWR

Pure copper heatsink with thermal pad cools M.2 2280 NVMe SSDs, measuring 70x20x4.0mm and including three rubber rings for mounting

  • Pure copper conducts heat at 401W/mk, far above aluminium
  • 0mm thickness adds surface area for faster heat dissipation
  • Fits 2280 NVMe and NGFF SSDs including popular models
  • Silicone thermal pad protects NAND chips while transferring heat
  • Three rubber rings secure the heatsink without tools

Pure Copper M.2 2280 Heatsink

This pure copper heatsink fits 2280 size NVMe and NGFF SSDs in desktops and laptops. The 70x20x4.0mm dimensions suit boards with enough clearance around the M.2 slot. A thermal pad and three rubber rings are included for secure mounting without damaging the drive components.

Capacity and headroom

The 4.0mm thickness provides extra surface area for heat exchange with ambient air. It covers controllers on drives such as the 970 EVO, 960 PRO, 950 PRO, PM981 and similar 2280 models. The copper conducts at 401W/mk, far above aluminium at 237W/mk, giving headroom for sustained write workloads on supported SSDs.

Thermals noise and power

Passive operation means zero fan noise and no power draw from the system. The thermal pad fills microscopic gaps between the drive and the copper base to maximise contact. Heat spreads through the copper fins and dissipates into the case airflow, lowering peak temperatures during heavy I/O without adding acoustic load.

Questions about this item

Will the 70x20x4.0mm copper heatsink clear a 2280 NVMe SSD on a motherboard with a tight PCIe slot?

The heatsink measures 70x20x4.0mm and is designed for 2280 NVMe and NGFF SSDs; verify motherboard clearance for the 4.0mm thickness before installation.

How can I confirm the copper heatsink is actually lowering my SSD temperature after fitting it?

Compare SSD temperatures in BIOS or monitoring software before and after fitting the 401W/mk copper heatsink with the included thermal pad under typical workload.

Does the package contain everything needed to mount the heatsink on a 2280 SSD, or must I buy extra parts?

The box includes one pure copper heatsink, one thermal pad and three rubber rings for mounting; no additional components are required.
