Unique-Bargains Aluminum Heatsink Cooler Black 20mm 5Pcs

SKU CH-0HB1-MRTWG

Aluminium heatsinks draw heat from memory chips and small ICs to lower failure risk

  • TypeHeatsinks only
  • Reduces overheating failure risk with aluminium thermal conductivity
  • Maximises air-contact surface area through finned 20 mm design
  • Cools memory modules and chipsets in desktop systems
  • Suits power transistors, ICs and LED components
  • Five-piece pack covers multiple components at once

What These Heatsinks Cover

Small aluminium fins measuring 20 mm square and 6 mm tall that press onto memory chips, voltage regulators, LED drivers or similar integrated circuits. They are sold as a pack of five for hobbyists, repair technicians or anyone adding passive cooling to a custom board.

Replacing Tape Or Nothing

The parts step in when a component ships with no heatsink at all or when the original thermal pad has dried out. The upgrade is worth it if the device runs hot enough to throttle or shorten its life, and if there is flat surface area for the 20 mm footprint to make full contact.

Press-On Mounting

Each fin relies on thermal adhesive or a thin pad to stay in place, so the mating surface must be clean, flat and free of tall capacitors that would prevent even pressure. Misalignment or insufficient pressure are the common reasons the heatsink falls off or fails to transfer heat.

Questions about this item

What size component will the 20 mm square heatsink cover?

Each heatsink measures 20 mm by 20 mm, so it covers a component footprint up to that size; verify your chip dimensions before fitting.

How are these heatsinks attached and what step is often missed?

They require thermal adhesive or tape; the step people skip is cleaning both surfaces with isopropyl alcohol first to ensure a solid bond.

When should the heatsinks be checked or replaced?

Inspect the bond if the component runs hotter than normal or after moving the board; replace a heatsink if the adhesive fails or the fin array is bent.
