Round-pin heat sinks provide superior cooling performance in two key areas: their ability to handle airflow from any direction (omnidirectional) and their excellent heat dissipation capability at low airflow. These properties make them highly resilient and indispensable in many applications where consistent and reliable cooling is critical.
- The omnidirectional characteristic allows airflow to come from any direction. And any change in airflow patterns (such as speed and direction) only has a minimum effect on their performance.
- Our standard round pin heat sinks are made from 1070 aluminum material whose thermal conductivity is much higher than other aluminum alloys such as 6063 and 6061.
- The round pin heat sinks are cold-forged from pure aluminum to ensure extremely high quality and thermal conductivity.
- S807 series are designed for natural convection and low airflow applications.
- S805 series are designed for medium to high airflow applications.
- Standard size ranges from 15×15 (0.6″x0.6″) to 125×100 mm (5″x4″), and height from 10 to 30 mm.
- For high aspect ratio, heat sinks can be as large as 250x200mm without requiring new tooling investment and customization is available.

Attachment Methods and Thermal Interface Materials
The S807 & S805 series are designed to work with thermal grease and adhesive tapes. Large-size heat sinks can also be attached using wire clips or spring-loaded methods. Push pins and captives screws are available as attachment options.
For thermal tapes, we recommend 3M 8810 and MHS T302.
How Are Round-Pin Heat Sinks Manufactured?
Using cold forging. Please follow this link to learn more about the features of cold forging and see examples of cold-forged heat sinks.
How Do We Test Heat Sinks?
At MyHeatSinks, we have a thermal laboratory where we can analyze heat sinks and measure the thermal resistance of heat sinks, heat pipes, CPU coolers, and other thermal modules with single or multiple heat sources. Our thermal test platform is connected to a wind tunnel, which allows users to set up the air flow rate, customize the enclosure size, and provide heating power to simulate the working environment of the heat sink. For more information about our thermal analysis of heat sinks, check out our Laboratory Services page, where we offer thermal analysis of heat sinks with single or multiple heat sources and forced convections.
Other Benefits of Cold-Forged Round-Pin Heat Sinks
In addition to the benefits mentioned above, round pin heat sinks are also the best solution for impingement cooling, which consists of a fan mounted on top of the heat sink (namely, fan-sink or CPU cooler).
Round pin heat sinks offer very low thermal resistance at low airflow rates. They are particularly good for natural convection, limited airflow, fan failure and highly populated PCB.
Round pin heat sinks also offer low-pressure drop due to their smooth pin shape. Low-pressure drop improves heat transfer in the entire system, especially the region behind the heat sink.
In cold forging, the pins are an integral part of the heat sink base – they are simply squeezed out of the base by high pressure. Unlike bonded fin heat sinks, there is no thermal resistance between the pins and the base in cold-forged heat sinks.
In addition to aluminum heat sinks, we also offer round pin heat sinks made of pure copper (C11000). Copper heat sinks typically improve thermal performance by 10-20%. They are recommended for critical applications where a few degrees of temperature reduction can make a big difference.
Build Your Own Heat Sink – Semi-Custom Heat Sink Optimized to Your Application
You can specify the width, length, and height of your heat sink. Our optimized semi-custom heat sinks are built for fast selection and deployment. There is no tooling cost, and the lead time for sampling and production is very short.
