      • Geekworm is the original designer and manufactuer of P165-A, P165-B, C235 & C296 heatsink.
      • Support customize the different specifications of standoff spacers for the heatsink! Please email us!!!

      This P165-B is an upgraded version of P165-A, which is perfectly compatible with POE Extension.
      This Embedded armor aluminum alloy heatsink/Radiator is design to slove Pi 4 excessive heat generation problem when use Raspberry Pi 4 with its expansion board. This heatsink can also be used with a 30mm cooling fan above.

      1. Why design this new P165-B 11mm embedded heatsink?

      A: We found that the copper spacers height required for most Raspberry Pi expansion boards is 11mm, so we designed this 11mm embedded heatsink(P165-B). Compared with the old model(P165-A), the heat dissipation area is increased and the heat dissipation effect will be better; at the same time, this new version support POE extension;

      2. What if the Raspberry Pi 4 expansion board comes into contact with the heatsink?

      A: Please use the 2*20 female header to add the height of expanion board. (If you need gpio extension, please refer to https://geekworm.com/products/geekworm-raspberry-pi-2x20-40-pin-gpio-stacking-header-extender-kit)
