40×40×11mm Black Aluminium Heatsink with 100 Cooling Pins for Electronics

Passive Cooling Heatsink for Chipsets, FPGA Boards, MOSFET Transistors and COB LED Modules

This 40×40×11mm aluminium heatsink is designed for efficient passive cooling of electronic components, chipsets, integrated circuits and power semiconductor devices. Its large cooling surface and specialised design featuring 100 vertical cooling pins help dissipate heat and maintain suitable operating temperatures for electronic equipment.

Manufactured from high-quality extruded aluminium with good thermal conductivity, the heatsink features a 10×10 matrix of individual cooling pins. The open grid structure allows air to flow freely between the pins from multiple directions, making it suitable for natural convection as well as additional forced-air cooling using a fan.

The black anodized finish protects the aluminium surface against oxidation and corrosion while improving thermal emissivity. Its compact 11mm height makes it suitable for installation in various electronic devices where mounting space is limited.

The bottom surface is flat and smooth. The heatsink is supplied without pre-applied thermal adhesive or double-sided thermal tape. This allows you to select the most appropriate mounting method for your application, including permanent thermal adhesive, double-sided thermal tape for easier removal, or thermal paste combined with mechanical fastening.

With its standard 40×40mm base, this model is suitable for cooling chipsets, processors, FPGA modules, stepper motor drivers, power components and other electronic devices.

Note: The heatsink is supplied without thermal paste, thermal adhesive or double-sided thermal tape. These must be purchased separately. Actual cooling performance depends on heat output, thermal contact quality and airflow. When cooling COB LEDs or TEC/Peltier modules, the specific power rating and thermal load must be taken into account. The 40×40mm dimensions alone do not guarantee compatibility with every factory mounting clip.
