Unique-Bargains 10 Black Aluminum Heatsinks 6x20x20mm Thermal Adhesive Chipset Cooling

SKU CH-STHX-MCYTC

Pack of 10 black aluminium heatsinks with thermal adhesive pads for chipset or 3D-printer motor cooling

  • Ten heatsinks cool multiple components in one pack
  • Thermal adhesive pads bond instantly for quick installation
  • 20 x 20 mm aluminium fins spread heat from chips
  • Black anodised finish suits 3D-printer motor cooling
  • Low 6 mm profile fits tight spaces like RAM modules

Ten-Pack Black Aluminum Heatsinks

This set supplies ten identical aluminum heatsinks measuring 20 x 20 x 6 mm each. They are intended for cooling memory modules, chipset components, stepper motors on 3D printers or similar small electronic parts. The black anodised finish matches dark-themed builds. Builders needing only one or two pieces should look elsewhere.

Pre-Applied Thermal Adhesive Pads

Every heatsink arrives with a thermal conductivity adhesive pad already attached. This eliminates the need for separate thermal paste or epoxy and reduces installation to a simple press-on action. The adhesive is permanent, so the heatsinks cannot be cleanly removed for reuse on another component.

6 mm Overall Height Constraint

The total height of each heatsink is 6 mm (0.24 inch). This single dimension determines whether the part fits between a motherboard and a graphics card, inside a slim laptop chassis or under a 3D printer motor cover. No other specification governs physical compatibility.

Questions about this item

Will the adhesive on these 20 mm aluminium heatsinks need replacing over time?

The thermal adhesive pads are pre-applied; if they lose grip or dry out you can clean the surface and add a thin layer of standard thermal tape or paste.

What stops these 6 mm tall heatsinks from cooling a stepper motor continuously?

Their small 20 x 20 mm fin area and 6 mm height limit how much heat they can radiate, so very high motor currents will eventually overwhelm passive dissipation.

Do the black anodised fins get hot or noisy during all-day 3D printer runs?

They are completely passive with no fan, so they make no noise; the aluminium body will become warm to the touch as it spreads heat into the surrounding air.
