Black aluminium heatsink with sixteen thin fins measuring 81 by 49 millimetres and 8.9 millimetres tall

Khadas

Khadas VIMs Heatsink 16 Fin 81x49mm Development Board

SKU CH-B590-K436Q

Sixteen-fin aluminium heatsink cools Khadas VIM and Edge-V single-board computers with included thermal pads and screws

  • 16 thinner fins fit the same space for denser heat dissipation
  • 0 W/mK thermal pads on every supported board ensure efficient transfer
  • 0 g lightweight 6063 aluminium adds minimal mass to the build
  • M2×4 and M1.4×4 mounts secure the heatsink and the 3705 cooling fan
  • Compatible with VIM1 through VIM4 and Edge-V SBCs

Universal SBC Heatsink

The Khadas VIMs heatsink fits every VIM single-board computer from the original VIM1 through the VIM4 and the Edge-V platform. M2x4 mounting holes and four dedicated thermal pads cover each board revision so one cooler serves an entire development fleet.

16 Fin Cooling Limit

Sixteen fins measuring 81.0 x 49.1 x 8.9 mm dissipate heat within the original board outline. The design excludes the 3004 cooling fan and VIM2 v1.2 or earlier boards, so builders using those parts must stay with the stock cooler.

Capacity and Headroom

A 5.0 W/mK silicone pad moves heat from the SoC into the 6063 aluminium body while the 3705 fan mount adds forced-air headroom for sustained loads. Without the fan the fin array handles typical edge workloads; prolonged peak compute will eventually saturate the passive path.

Questions about this item

Which thermal pad should I use for my specific VIM or Edge board?

Match the pad colour to your board: grey 20×20×1.3 mm for VIM3, VIM3L, VIM4; blue 20×20×1.0 mm for VIM1, VIM1S, VIM2 v1.4+; off-white 22×22×0.7 mm for Edge2, Edge-V; pink 22×22×0.4 mm for Edge.

What does the 5.0 W/mK conductivity mean for my board temperatures?

The 5.0 W/mK silicone pads on VIM and Edge-V models move heat from the SoC to the 16-fin aluminium heatsink efficiently, keeping the processor cooler under sustained load.

Can I mount the 3705 cooling fan on this heatsink?

Yes, the heatsink includes M1.4×4 fan mounting holes designed for the high-airflow 3705 fan; the older 3004 fan is not compatible.
