Unique-Bargains Chipset Heatsink 9 x 9 x 12 mm Black 10pcs

SKU CH-Y670-FYCNC

Pack of ten 9 x 9 x 12 mm aluminium heatsinks with pre-applied thermal adhesive tape for cooling small chips and stepper motor drivers

  • Aluminium alloy draws heat away from small chips
  • Pre-applied conductive tape bonds instantly without extra paste
  • Ten heatsinks cover multiple drivers or memory modules
  • Compact 9 × 9 × 12 mm footprint fits tight board spaces
  • Works best when paired with case airflow for active cooling

Compact Chipset Heatsink Set

These black aluminum heatsinks measure 9 x 9 x 12 mm and come in a pack of 10. They are designed for small chips, stepper motor drivers and other compact electronics that lack factory cooling. Pre-applied thermal adhesive tape simplifies installation on clean, dry surfaces. Builders needing larger or taller coolers will need a different solution.

Passive Cooling With Airflow Dependency

The heatsinks rely on case airflow to dissipate heat; they do not move air themselves. A separate fan is recommended to maintain a temperature gradient across the fins. Thermal conductive adhesive tape is already attached for optimum heat transfer. Systems with restricted airflow may see limited benefit.

Sustained Load Behaviour

Under continuous load the aluminum absorbs heat until it reaches equilibrium with the surrounding air. Performance scales with the volume and direction of airflow over the fins. Without forced air the heatsinks will saturate and temperatures will rise. They are not suited for high-power components that generate sustained thermal loads beyond what passive dissipation can handle.

Questions about this item

How do I install the 9 x 9 x 12 mm aluminium heatsinks with the pre-applied adhesive tape?

Clean and dry the chip surface thoroughly, then peel the backing from the pre-applied thermal tape and press the heatsink firmly into place; the tape bonds instantly so alignment must be correct first time.

Will the adhesive tape on these 10 heatsinks need replacement later?

The pre-applied thermal tape is intended as a permanent bond; if a heatsink is removed the tape cannot be reused and a new thermal pad or adhesive would be required.

What limits cooling performance of these 12 mm tall heatsinks during sustained loads?

They rely entirely on external airflow — without a fan moving air across the fins the aluminium saturates quickly and temperatures rise.
