Heat River Tech LTD heat sink 45x45x18 mm silver

SKU CH-W4BJ-4KYEA

Silver heat sink measuring 45 by 45 by 18 millimetres for component cooling

  • Silver finish improves thermal radiation
  • Passive cooling with no moving parts to fail

Compact aluminium heat sink

The Heat River Tech LTD heat sink measures 45 by 45 by 18 millimetres and is finished in silver. It is designed to draw heat away from small electronic components such as voltage regulators, memory modules or embedded processors. The lightweight aluminium construction suits hobbyist projects and compact enclosures where active cooling is impractical. It arrives new and ready for immediate installation.

Supplied without mounting hardware

No thermal pads, adhesive tape or screws are included in the package. Builders must source their own interface material and fastening method to suit the target component. This makes the part less convenient for quick repairs but allows flexible attachment in custom layouts. Users needing a complete kit should look for a product that bundles those accessories.

Questions about this item

Will the fins or base of this 45x45x18 mm silver heat sink ever need cleaning or replacement?

The aluminium fins and base are solid pieces with no moving parts; only occasional dust removal with compressed air is required, and no component wears out under normal use.

What thermal limit appears first when this 45x45x18 mm silver radiator runs continuously?

Its small 45 by 45 mm footprint and 18 mm height restrict surface area, so the heat-sink-to-ambient thermal resistance becomes the bottleneck before the aluminium itself saturates.
