Unique-Bargains Aluminum Heatsink 22mm 10mm 5pcs

SKU CH-SKXZ-F0H4N

Set of five 22 mm square aluminum heatsinks, 10 mm tall, to cool memory chips, ICs, LEDs and power transistors

  • TypeHeatsinks only
  • Reduces overheating risk with high-conductivity aluminium construction
  • Maximises cooling surface area through finned 22 mm square design
  • Low 10 mm profile fits tight component clearances
  • Five-piece set covers multiple ICs or LED drivers
  • Compatible with power transistors, semiconductors and integrated circuits

Five-piece aluminium heatsink set

This pack contains five black aluminium heatsinks measuring 22 mm by 22 mm by 10 mm. They are intended for circuit-board components such as memory modules, power transistors, integrated circuits or LEDs that need passive thermal relief.

Increased surface area for passive cooling

Each finned block maximises the contact area with surrounding air, allowing heat to dissipate without a fan. The aluminium construction provides good thermal conductivity so components run cooler and face a lower risk of overheating failure.

Limited to low-power, space-constrained devices

The 10 mm height and 22 mm footprint restrict use to components that physically fit and generate modest heat. Builders needing to cool high-wattage GPUs, CPUs or voltage-regulator modules will require larger or active solutions.

Questions about this item

Will the adhesive on these 22mm x 22mm x 10mm heatsinks need replacing over time?

The adhesive bond can degrade after repeated thermal cycles; plan to re-apply thermal tape or epoxy if a sink becomes loose.

What thermal limit appears first when these aluminum fins run continuously?

The small 10mm height limits heat capacity, so the component temperature rises until the fin-to-air interface reaches equilibrium.

How much noise and heat do these passive 22mm squares add to a system running all day?

They add zero noise and only the heat conducted from the attached device; no fan or power draw is involved.
