40mm Heatsink Information

Technical Information on the Heatsinks

  • Thermal power calculations for Hifi2000 40mm Heatsinks (PDF)
  • 100% Aluminum
  • All heatsink fins are "wave" profile for increased surface area
  • Heatsinks are black anodized for improved emissivity.
  • Great care is taken in the factory to ensure that external surfaces are blemish free.
  • The interior surface will have one thin mark in the corner where the anodization isn't present. This is a normal artefact of the anodization process.
  • Deluxe Chassis heatsinks are tapped with M3 threads to a minimum depth of 5mm
  • The "base" is a minimum thickness of 8mm
  • The fin pitch is 6mm (distance between each fin, "tip to tip")
