Heat River Tech LTD 28x28x15mm Silver Slot Heat Sink

SKU CH-M8ZE-PT23S

A compact 28×28×15 mm silver-slotted heat sink with a thick substrate for efficient component cooling

  • Compact 28x28 mm footprint fits tight spaces
  • 15 mm low profile clears low-clearance builds
  • Silver slot finish resists oxidation for lasting performance
  • Thick substrate spreads heat evenly across the base

Compact Silver-Slot Heat Sink

This 28 mm square heat sink with a 15 mm profile fits tight spaces where larger coolers cannot be installed. The silver-slot design and thick substrate provide a solid thermal path for small-scale components. It suits hobbyists and engineers who need passive cooling on a single chip or module.

Direct Replacement for Undersized Spreaders

The unit upgrades from basic flat spreaders or adhesive pads that cannot move heat fast enough under sustained load. The jump is worthwhile when the component runs hot enough to throttle or when the enclosure offers no airflow for active cooling. Buyers who need to cool multiple devices or larger surface areas should look elsewhere.

Questions about this item

Will the 28 mm square footprint fit my component?

The heat sink measures 28 mm by 28 mm at the base, so it fits any device with a matching or larger flat surface.

How do I attach the silver-slot heat sink and what step is often missed?

Apply thermal paste to the thick substrate, press the 15 mm tall sink onto the chip, then secure it with clips or adhesive; the step often missed is cleaning both surfaces first.
