Aluminium Heatsink 20x20x6mm

This pack contains ten aluminium heatsinks measuring 20x20x6mm. They are designed for DIY cooling of motherboard chipsets, GPU components, 3D printer drivers, and single-board computers such as Raspberry Pi. Each heatsink comes with 3M 9448a thermal double-sided adhesive tape pre-applied for efficient heat transfer.

Installation notes

Peel the protective liner and press the heatsink firmly onto the target IC for a few seconds. The 3M 9448a tape bonds quickly, so align carefully before contact. If repositioning is needed, a thin razor blade can slide under the heatsink to release it without damaging the chip surface.

Pre-order checks

Verify that the component you intend to cool has a flat top surface at least 20mm x 20mm with 6mm vertical clearance above it. Ensure no neighbouring parts or cables will interfere with the heatsink once installed. Buyers who need larger footprints or taller fin stacks for higher thermal loads should look for alternative sizes.

Questions about this item

How can I tell the heatsinks are working after I stick them on?

Touch the aluminium fins after the device has run under load; they should feel warm, showing heat is moving from the chip into the heatsink.

What comes in the pack and do I need anything else to install them?

The pack contains ten 20x20x6mm aluminium heatsinks with 3M 9448a thermal tape already applied; no extra adhesive or tools are required.

Which version should I choose for an A4988 stepper driver on a 3D printer?

These 20x20x6mm heatsinks match the A4988 package size and include the thermal tape, so the single listed version is the correct one.
