Pack of ten 25×25×5 mm black heat sinks for component cooling

Pack of ten 25 mm heat sinks

This set provides ten black anodised aluminium heat sinks, each measuring 25 by 25 by 5 millimetres. They are intended for attaching to small electronic components such as voltage regulators, memory chips or motor drivers. The pack suits hobbyists and engineers who need multiple identical pieces for a single project or for spares.

Steady dissipation over burst handling

The thin 5 millimetre profile and modest surface area limit the thermal mass available for prolonged loads. Under continuous power the sinks will reach equilibrium quickly and cannot absorb sustained high wattage without forced airflow. They are not suited for components that run hot for long periods without active cooling.

Questions about this item

How much heat does each 25 by 25 millimetre sink dissipate when running continuously?

The small aluminium fins spread warmth from low-power chips, but no thermal-resistance or wattage rating is published for these 25 by 5 millimetre pieces.

What mounting hardware or thermal paste do I need to attach the 10 sinks?

The pack contains only the ten black anodised blocks; you must supply your own thermal adhesive, paste, tape or mechanical clips to suit the target component.
