Heat Sinks for Fansinks – Standard Configuration

Heat Sinks for Fansinks > Standard

Provide outstanding cooling power in a compact envelope
Copper fansinks are suitable for extreme cooling needs and for scenarios that require rapid heat spreading
Aluminum fansinks are designed for the majority of cooling scenarios
Low profile fansinks are available for vertically-constrained applications (standard heat sinks as low as 0.2", custom as low as 0.15")
Pre-drilled mounting holes allow for quick and simple fan mounting (30mm, 40mm & 50mm fans)
Pre-assembled threaded standoffs allow for quick and simple fan mounting (60mm fans)
Lapped in order to reduce the contact resistance between the heat sink and the device
Available with double-sided thermal tape
Pin fin heat sinks for fansinks range from a footprint of 1.25" x 1.25" to a footprint of 2.50" x 2.50" and from a heat sink height of 0.2" to a heat sink height of 1.7"

Aluminum pin fin heat sinks for fan sinks are manufactured via the Cold Forging process
The cold forging process allows for the use of highly conductive aluminum and copper alloys
The process ensures that no air bubbles, cavities or any other impurities are trapped within the material

Aluminum pin fin heat sinks are forged from pure aluminum (AL1100)
The thermal conductivity of AL 1100 is 1510 btu/in ft2 hr of. (~50% higher than AL 380, a common cast alloy)
Copper pin fin heat sinks are forged from pure copper (CDA 110)
The thermal conductivity of CDA 110 is 2712 btu/in ft2 hr of. (~100% higher than AL 380, a common cast alloy)

Pin fin heat sinks for fansnks are lapped
The lapping process significantly improves the flatness and the surface finish of the base of the heat sink, when compared to conventional base finishing processes
The contact resistance between the heat sink and the device is reduced significantly following the completion of the lapping process
Flatness: Better than 0.001 inch/inch
Surface Finish: 16 RMS or better
