This dual-fan heatsink is a simple and affordable cooling solution for your Raspberry Pi.
The heatsink includes an adhesive thermal tape on the underside which secures the heatsink to your Raspberry Pi's CPU. Once fitted, the heat from your Raspberry Pi's CPU spreads along the heatsink and is cooled via the two fans.
Power is provided by the Raspberry Pi GPIO - just connect the red wire side the the 5V pin, and the black wire side to a GND pin as pictured.
Compatible with the Raspberry 4 and 3B+.
Note: apply pressure for 30-60 seconds when fitting.
