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.
