Unique-Bargains 7x7x6mm Black Aluminum Heatsink 20 Pcs

SKU CH-J1AH-ZY3GG

Pack of twenty 7 x 7 x 6 mm black aluminium heatsinks with self-adhesive thermal pads for chip-level cooling

  • ColorBlack
  • Cools chips effectively with included thermal adhesive
  • Strong stickiness keeps heatsinks firmly in place
  • Aluminium alloy dissipates heat quickly
  • Compact 7 x 7 x 6 mm size fits tight spaces
  • Pack of 20 covers multiple components

Compact 7 mm Heatsinks for Small Chips

This pack contains twenty black aluminium heatsinks measuring 7 x 7 x 6 mm. They are designed for ICs, MOSFETs, stepper-motor drivers and similar components that have no factory cooling. The self-adhesive thermal pad on each piece removes the need for separate paste or clips. Hobbyists repairing 3D-printer boards or upgrading RAM modules will find the quantity convenient.

Pre-applied Adhesive Speeds Installation

Each heatsink ships with a thermal-conductivity adhesive layer already attached. The pad provides both mechanical bonding and a heat-transfer path, so installation takes only seconds. No additional thermal compound, tape or fasteners are required, which keeps the work area clean and reduces the chance of short circuits on dense PCBs.

Low-profile Aluminium Fits Tight Spaces

The 6 mm height and 7 mm footprint let these sinks sit between closely spaced components or inside slim enclosures. Aluminium alloy construction gives a lightweight yet effective spreading surface for modest heat loads. The black finish is purely cosmetic and does not affect thermal performance. Buyers needing taller fins, larger footprints or active airflow should look elsewhere.

Questions about this item

Will the adhesive on the 7x7x6mm heatsinks need replacing over time?

The heatsinks use a thermal conductivity adhesive with strong stickiness; if the bond weakens after prolonged heat cycles, the pad can be peeled off and replaced with a fresh thermal adhesive.

What thermal limit appears first when these 7x7x6mm aluminum heatsinks run continuously?

The small 7x7x6mm aluminum alloy body has limited mass and surface area, so its heat-soak capacity is the first bottleneck under sustained load.

How much noise, heat or extra power do 20 of these 7x7x6mm heatsinks add when installed all day?

They are passive aluminum pieces with no moving parts, so they add zero noise, draw no power and only radiate the heat they pull from the attached chips.
