Like all electronic products, Raspberry Pi generates waste heat as it works. Along with most fanless products – like most mobile phones – Raspberry Pi 4 was originally designed to operate in a “sprint-and-recover” mode: if run at maximum performance for an extended period it would heat up, and eventually throttle back to limit its temperature.

Whats included:

X1 unit Offical RPI 4 Fan
