DIY Aluminium Heatsink Pack

This pack contains five black anodised aluminium fin heatsinks measuring 28 x 28 x 11 mm each. They are designed for DIY cooling of small electronic components such as chipsets, voltage regulators, power transistors, FETs, ICs, 1 W LEDs, RAM modules and GPU memory. The low-profile fins increase surface area to improve passive heat dissipation. Adhesive glue is required for mounting and is not included.

Passive Fin Cooling Limits

Each heatsink relies solely on natural convection and radiation to move heat away from the component. Without forced airflow the thermal capacity is modest, so the parts are suited to low-power devices rather than high-wattage processors. The 11 mm height restricts fin density, limiting total dissipation area. Performance drops quickly if the ambient temperature rises or if the contact surface is uneven.

Capacity and Headroom

The 28 mm square footprint covers many common chipset and VRM packages, while the 50 g total pack weight confirms the lightweight aluminium construction. They comfortably handle small ICs and 1 W LEDs but run out of headroom on larger GPUs or CPU dies that exceed the contact area. Always verify that the 1.10 inch dimensions match your target component before applying adhesive.

Questions about this item

How many heatsinks come in this pack?

The listing supplies five identical aluminium fin heatsinks per lot, so one pack covers multiple small components such as VRM chips or memory modules.

What thermal improvement can I expect from a 28 by 28 by 11 millimetre finned block?

The anodised black fins increase surface area, letting each 50 gramme heatsink passively draw heat from ICs like MOSFETs, voltage regulators or 1 W LEDs without airflow.

How do I attach these heatsinks without a mounting bracket?

Use thermal adhesive glue (not included) to bond the flat base directly onto the chip package; the low 11 millimetre profile clears most neighbouring components.
