Aluminium Heatsinks for Chips and Modules

These silver aluminium heatsinks measure 40 x 40 x 20 mm each and come in a pack of four. They are designed to cool MOS, GPU and IC chips as well as stepper motor driver modules that lack factory cooling. The parallel line notch design increases surface area for better heat transfer.

Adhesive Required for Installation

No thermal tape or adhesive is included so you must supply your own glue or thermal pads. The flat base makes contact with the component and the lightweight alloy adds minimal stress to the PCB. Each unit fits within a 40 mm square footprint, leaving surrounding board space free.

Passive Cooling with No Noise

The aluminium alloy construction moves heat away from the chip without any moving parts. There is no fan to generate noise or draw power. Thermal performance depends on the adhesive used and the airflow inside the case.

Questions about this item

What is the 20 mm height limit for airflow clearance above the heatsink?

The heatsink stands 20 mm tall, so any case fan or side panel must leave at least that much space above the component.

How hot does the aluminum get during continuous operation?

The aluminum alloy body spreads heat across its 40 x 40 mm fins, staying warm to the touch but well within safe limits for MOS, GPU and IC chips.

Which adhesive must I supply to mount the four heatsinks?

No thermal tape or glue is included; you need a suitable thermal adhesive or epoxy to bond each 40 x 40 mm piece to the chip.
