Unique-Bargains Black Aluminum Heatsink Set 14x14x7mm 8.8x8.8x5mm 20pcs
Set of 20 black aluminum heatsinks in two sizes with self-adhesive backing for Raspberry Pi 2B and other small electronics
- Aluminium alloy transfers heat efficiently from small components
- Self-adhesive backing attaches securely without conductive paste
- Two sizes fit Raspberry Pi 2B and other compact chips
- Twenty pieces in ten sets cover multiple boards or spares
- Black finish blends discreetly inside enclosures
Raspberry Pi 2B and small-chip cooling
This set of 20 black aluminum heatsinks targets Raspberry Pi 2B owners and anyone cooling stepper drivers, ICs or other compact electronics. Ten pieces measure 14 x 14 x 7 mm and ten measure 8.8 x 8.8 x 5 mm, covering a range of component footprints. The adhesive-backed design lets hobbyists add thermal relief without tools or thermal paste.
Passive aluminium with ordinary adhesive
Each heatsink uses aluminum alloy to spread heat from the component surface into the fins. The self-adhesive layer is non-conductive and provides strong stickiness for a secure bond. Because the cooling is entirely passive, the kit adds no fan noise and draws zero power during operation.
Two heights for mixed board layouts
The taller 7 mm pieces and lower 5 mm pieces allow clearance around neighbouring components on dense PCBs. Black anodising gives a uniform appearance across both sizes. Buyers needing conductive thermal tape or larger footprints for high-power GPUs should look elsewhere.

Questions about this item
How do I install the 14x14x7mm and 8.8x8.8x5mm heatsinks, and what step is often missed?
Clean the chip surface with isopropyl alcohol, let it dry, then peel the backing and press each heatsink firmly for several seconds; the step often missed is skipping the cleaning, which weakens the adhesive bond.
Will the self-adhesive on these 20 aluminum heatsinks need replacement over time?
The ordinary non-conductive adhesive can lose stickiness after repeated heat cycles; if a heatsink loosens, remove the old pad, clean the surface, and apply a new thermal adhesive pad or tape.
What thermal limit appears first when these heatsinks run continuously on a Raspberry Pi 2B?
The small 14x14x7mm and 8.8x8.8x5mm fin area saturates quickly, so the chip temperature rises until the board throttles; sustained loads hit this passive limit faster than active cooling would.
