Copper heatsink for M.2 2280 SSD, 70x20x4.0mm with thermal pad and rubber rings

EN-Labs

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

SKU CH-AW7R-R886B

Pure copper heatsink with thermal pad cools 2280 M.2 SSDs using 401 W/mk conductivity

  • Pure copper conducts heat at 401 W/mK for faster cooling
  • 0 mm thickness adds surface area for better heat dissipation
  • Supports 2280 NVMe and NGFF M.2 SSDs
  • Included thermal pad protects SSD chips and extends drive life
  • Three rubber rings secure the heatsink without tools

Copper heatsink for 2280 SSDs

This pure copper heatsink measures 70x20x4.0mm and includes a thermal pad plus three rubber rings for mounting. It is designed for NVMe and NGFF M.2 solid-state drives in the 2280 form factor. The copper construction provides thermal conductivity of 401W/mk, which is higher than aluminium at 237W/mk. It suits desktop systems with enough clearance for the 4.0mm thickness.

Replaces bare-drive operation

The heatsink upgrades an M.2 SSD that currently runs without any cooling hardware. The jump is worth it when sustained workloads cause thermal throttling or when the drive sits in a poorly ventilated slot. Drives such as the 970 EVO, 960 PRO, 950 PRO, 860 EVO, 850 EVO, 750 series and PM981 are listed as compatible examples. The larger surface area helps exude heat faster through contact with air.

Check clearance and chip dimensions

Before ordering, measure the controller and memory chips on your M.2 drive to confirm they fit within the 70x20mm footprint. Verify that your motherboard or laptop has enough vertical space for the 4.0mm heatsink plus the thermal pad. Ensure the drive uses the 2280 length and that the mounting holes or rubber rings can secure the assembly without interfering with nearby components.

Questions about this item

Will the 70x20x4.0mm heatsink clear my motherboard M.2 slot and nearby components?

The copper block measures 70 mm long, 20 mm wide and 4.0 mm thick; verify your board has at least that much clearance around the 2280 SSD before fitting it.

Do I use the included thermal pad or the three rubber rings to attach the heatsink to my 2280 NVMe drive?

Place the silicone thermal pad between the SSD and the copper heatsink, then secure the assembly with the three supplied rubber rings.

When should I replace the thermal pad on this copper heatsink?

Replace the pad if it dries out, tears during a drive swap, or after several years when thermal performance drops.
