Pack of five aluminium heatsinks

Five anodised black aluminium heatsinks measuring 25mm by 25mm by 5mm each. They are intended for DIY cooling of motherboard chipsets, power transistors, FETs, voltage regulators and similar small ICs. Supplied as a lot of five pieces for multiple components or spares.

Thermal capacity and limits

The 25mm square footprint and 5mm thickness suit low-profile chips with modest heat output such as chipset or VRM devices. Thermal headroom is limited by the small surface area and lack of forced airflow, so they are not adequate for high-wattage processors or sustained heavy loads.

Build and mounting practicalities

Each unit weighs 20g and features a black anodised finish that resists corrosion. Installation requires thermal adhesive glue, which is not included, so buyers must source a suitable compound separately. Verify the component dimensions before fitting to ensure full contact.

Questions about this item

Will the 25 mm square footprint clear the surrounding capacitors on my older motherboard chipset?

Each heatsink measures 25 mm by 25 mm in plan, so measure the clear area around your chipset before fitting.

How can I verify the 20 g aluminium pieces are making good thermal contact after gluing?

After the adhesive cures, run a load test and check that the chipset temperature drops compared with the bare die.

The pack lists five heatsinks — is thermal adhesive or mounting hardware included?

The box contains only the five anodised black aluminium heatsinks; thermal glue must be purchased separately.
