Heat Sinks for Fansinks > Overview
- Standard pin fin heat sinks are available for 30mm, 40mm, 50mm & 60mm fans
- Integrated pin fin fansinks offer unique low profile solutions
- Pin fin fansinks generate remarkable cooling power in a low profile envelope and outperform the majority of other fan sink technologies by a substantial margin
- Standard fansinks are composed of a pin fin heat sink and a fan placed directly on top of the heat sink
- Integrated fansinks are composed of a pin fin heat sink and a fan that is embedded into the pin array
- Standard and Integrated fansinks are available in copper and aluminum variations
- Due to their unique structure integrated fan sinks offer extreme low profile fansink solutions
- Overall height can be modified to fit application specific requirements
- Cool innovations' heat sinks are lapped in order to reduce the contact resistance between the heat sink and the device
- Standard fansinks range from a footprint of 1.23" x 1.23" to a footprint of 2.5" x 2.5" and from a height of 0.2" to a height of 1.7" (Fan height not included)
- Integrated fansinks range from a footprint of 1.78" x 1.78" to a footprint of 4.10" x 2.05" and from a height of 0.42" to a height of 0.63" (Fan height included)
| Feature | Benefit |
|---|---|

| Flexible manufacturing | - Enables the provision of custom heights without tooling charges
- Allows for low profile fansinks |
| Highly conductive materials | - Additional cooling power due to higher thermal conductivity
- Superior heat spreading capabilities |
| Forging technology | - Ensures that no air bubbles, cavities or other impurities exist in the material |
| Lapped base finish | - Significantly flatter bases
- Reduced contact resistance between the heat sink and the device |
| Configuration | Material | Footprint | Height | Fan Size |
|---|---|---|---|---|
| Standard | Al, Cu | 1.25" x 1.25" - 2.50" x 2.50" | 0.2" - 1.7" | 30mm - 60mm |
| Integrated | Al, Cu | 1.78" x 1.78" - 4.10" x 2.05" | 0.42" - 0.63" | 38mm Bracket Fan |
- Impingement cooling consists of a fan being placed directly on top of the heat sink, in a perpendicular fashion
- Impingement cooling provides up to a 20 per cent performance premium when compared to traditional cooling from the side
- In the impingement cooling mode, the air is distributed evenly along the surface of the heat sink, thus eliminating the temperature gradient that is typical to horizontal cooling. The larger the heat sink, the more significant this effect is
- The additional cooling power stems from the increased air turbulence between the pins in the impingement cooling mode
