Geekworm Heatsinks: 2 Picks Ranked by Specs
The Geekworm lineup offers two distinct aluminum heatsinks for Raspberry Pi users. The top pick is the Geekworm 12mm Aluminum CM4 Heatsink. It features a slim 12 mm profile. This design suits builds requiring low height. It fits well in tight spaces where a fan adds airflow. The second option is the Geekworm Aluminum Passive Raspberry Pi 5 Heatsink. It stands at 15 mm. This model targets silent builds. It prioritizes noise reduction over fan compatibility. Both units use aluminum for heat dissipation. You choose based on your case constraints. The first fits CM4 modules. The second supports Raspberry Pi 5. Consider your available vertical space. Check your compatible device list. Match the dimensions to your project needs. This ensures proper fit and cooling performance.
Who Should Buy Geekworm Heatsinks
This brand suits builders who prioritize compact dimensions and silent operation for Raspberry Pi systems. You can choose between a 12 mm active-ready aluminum block or a 15 mm passive option. Both use aluminum for heat dissipation. The range covers single-board computers like the CM4 and Raspberry Pi 5. You will not find RGB lighting or active fans included. There are no copper base options listed. If you need larger surface areas or different mounting styles, this specific lineup may not fit your case constraints. Check your height limits before purchasing.
How to choose the right one
-
Match the device type
You must verify that the heatsink is compatible with your specific single-board computer. The Geekworm C235 is designed for the Raspberry Pi Compute Module 4. The H509 model targets the Raspberry Pi 5. Using a heatsink on an unsupported board will not provide effective cooling. Check the compatible device field in the specifications before purchasing. This ensures the mounting holes and surface area align correctly with your hardware.
-
Check physical dimensions
Measure the available space in your case before selecting a model. The Geekworm C235 has a height of 0.47 inches. This slim profile suits builds with tight clearances. The H509 measures 0.59 inches in height. If you need silence, this slightly taller block works well. Compare the width and length against your case interior. Ensuring the physical dimensions fit prevents installation issues and maintains proper airflow around the component.
-
Decide on cooling method
Choose between passive and active cooling based on your noise requirements. The H509 is a passive heatsink. It relies on natural air convection. This method produces zero noise. It is ideal for silent environments. The C235 supports fan attachment. This allows for active airflow. You can add a fan to move air across the fins. Select the method that matches your acoustic and thermal needs.
-
Evaluate material properties
Both listed models use aluminum as the primary material. Aluminum offers a good balance of weight and thermal conductivity. It is lighter than copper options. This makes it easier to handle during installation. The material conducts heat away from the chip effectively. Ensure the aluminum surface is clean before installation. This maximizes thermal transfer. The material choice impacts both performance and the overall weight of your project.
-
Consider weight limits
Check the weight of the heatsink if you are using fragile mounts. The C235 weighs 0.71 ounces. This is a light load for the board. The H509 weighs 1.55 ounces. It is heavier due to its larger size. Ensure your mounting hardware can support the weight. Excessive weight may stress the solder joints or the board itself. Lightweight designs are often preferred for portable or suspended Raspberry Pi builds. Verify the weight in the specs.
