“Awesome SHIM for the RPI 4 since cooling is necessary. The fan and the provided python program work perfectly. The fan itself doesn't create a lot of noise.”
“Quality product that fits nicely to help reduce the temperature. It's real quiet too and the software is great to tweak when the fan is triggered. Fantastic documentation online to help you through the process end to end. Would recommend folks grab this because the Pi4 is a hotter than you might have envisaged. Don't do what I did and pay for delivery again. Buy it when you get your pi. Fast delivery from the guys as always.”
