CanaKit Raspberry Pi 5 large metal heatsink for a great cooling solution for your Pi 5. Fits inside the CanaKit Raspberry Pi 5 Turbine Case. It is large enough for passive cooling and heat dissipation yet with a low enough profile to fit inside the enclosure and leaving room for various HATS. Includes transfer pads already fitted on the touchpoints to the main Raspberry Pi 5 chips. Recommended to use in conjunction with the CanaKit Raspberry Pi 5 Turbine Case and CanaKit Pi 5 Low-Noise Fan.
