“This has, so far, proved a really effective means of keepinng the RPi4 below the 80C at which the device starts self-throttling. The CPU of my RPi4 starts getting hot very quickly under load, rising from (resting) 50C to (busy) 70C within a minute. The fan SHIM can bring this down quickly under intermittent load, or keeps the temperature at about 70C under constant high load. I'll be interested to see how it behaves in summer, and its temperature-colour-coded leds are about as exciting as life has got under COVID-19 house arrest.”
“Perfect device. Simple to install, simple instructions to follow on the website, even for a novice such as myself. Brilliant piece of kit, does exactly what it says on the tin and every Raspberry Pi should have one.”
“I’ve had a few of these installed since the Pi4 launched and they’ve been running 24/7 ever since. Only had one failure within a month of purchase but the brilliant Pimoroni team replaced it for free and it arrived next day. Brilliant service, thanks guys!”
