Thin copper M.2 heatsink 70x20x1.5mm with thermal pad and rubber rings

EN-Labs

EN-Labs M.2 SSD Copper Heat Sink 70x20x1.5mm diy cooling

SKU CH-BC3J-XSVWW

A pure copper heatsink with a 401 W/mk thermal pad cools 2280 NVMe SSDs in a 1.5 mm slim profile for laptops and tight spaces

  • Pure copper conducts heat at 401W/mk, far above aluminium's 237W/mk
  • 5mm slim profile fits 2280 NVMe drives inside tight laptop spaces
  • Included thermal pad protects SSD chips while transferring heat to the heatsink
  • Three rubber rings secure the cooler without tools or adhesives
  • 70x20mm footprint matches common M.2 modules for direct drop-in cooling

Compact M.2 heatsink for tight builds

This pure-copper cooler measures 70x20x1.5mm and fits 2280-size NVMe and NGFF drives. A thermal pad and three rubber rings are included for tool-free mounting. The 1.5mm profile suits laptops and other cramped chassis where taller heatsinks cannot be installed.

Sustained heat transfer from copper mass

Copper conducts at 401W/mk, nearly double the 237W/mk of aluminium, so the fin array draws heat from the controller and NAND continuously rather than saturating quickly. The pad bridges microscopic gaps to keep thermal resistance low during long write sessions. No moving parts means performance does not degrade over time.

Silent operation with minimal power impact

The heatsink adds no fan noise and draws no electricity, relying solely on convection and case airflow. At 1.5mm thick it does not obstruct adjacent components or restrict airflow in slim notebooks. The rubber rings secure the assembly without stressing the PCB or M.2 slot.

Questions about this item

How much heat can the 70x20x1.5mm copper heatsink move during continuous operation?

The pure copper body conducts heat at 401W/mk, far above aluminium's 237W/mk, and the finned surface exchanges that heat directly with surrounding air.

What else must I already own to install this heatsink on my drive?

You need an M.2 2280 NVMe or NGFF SSD with a controller area that matches the 70x20mm footprint; the kit supplies the thermal pad and three rubber rings for mounting.

Will this 1.5mm cooler fit alongside a laptop motherboard that already has a thin thermal pad on the SSD?

Yes — the 1.5mm profile is designed for tight laptop bays; place the included silicone pad between the copper and the drive, then secure with the rubber rings.
