Copper Heatsink Kit for Raspberry Pi

This kit supplies a 14 x 12 x 5.5 mm copper heatsink and two 8.8 x 8.8 x 5 mm aluminium heatsinks, all pre-coated with thermal adhesive tape. The parts are sized to fit the Raspberry Pi CPU and LAN or RAM chipsets inside standard cases. Copper thermal conductivity is rated at 401 W/mK for the main heatsink. The set targets DIY builders who need drop-in cooling for single-board computers.

Pre-Applied Thermal Adhesive Simplifies Mounting

Each heatsink arrives with a layer of thermal adhesive already attached, so no separate paste or pads are required. The tape bonds on contact and can be lifted later with a razor blade without damaging the underlying chips. This arrangement removes the mess and alignment hassle of manual thermal-interface application. The low profiles keep clearance tight for enclosed enclosures.

Verify Board Layout and Case Clearance Before Buying

Confirm that your board’s target chips match the 14 x 12 mm and 8.8 x 8.8 mm footprints; the adhesive is not repositionable once seated. Measure internal case height to ensure the 5.5 mm and 5 mm profiles do not contact the lid. The kit is intended for Raspberry Pi and similar small-form-factor boards; it will not cover larger desktop CPUs or multi-chip arrays.

Questions about this item

Will the thermal adhesive on these 14x12x5.5mm and 8.8x8.8x5mm heatsinks need replacing?

The adhesive is designed for permanent attachment; if removal is needed, a razor blade can separate the heatsink without chip damage, after which fresh thermal tape must be applied for reattachment.

What thermal limit appears first when the copper heatsink runs continuously on a Raspberry Pi CPU?

The copper heatsink relies on passive convection; under sustained load the limiting factor is the case airflow's ability to carry heat away from the 401 W/m·K copper surface.

How much noise and heat does the kit add when the board runs all day?

The kit adds zero noise because it has no moving parts; the heatsinks simply spread heat into the case, so internal temperature rise depends entirely on the enclosure's ventilation.
