“Previously I tried to cool my Raspberry 4 with a simple heat sink, but it was overheated all the time. With this I couldn't overheat it a single time so far (also it is really silent)”
Ahoy! You can program the switch and light to do a variety of things, but in our example the LED shows the temperature of the Pi and the button provides an override for the automatic script - more info here: https://learn.pimoroni.com/tutorial/sandyj/getting-started-with-fan-shim
“Brilliant!! was tricky to put together with my Shrek size hands getting the lead from the fan into the board but got there in the end using tweezers, screws have a nice tight fit and good threads even being plastic. Fan was so easy to install just literally place it onto the end pins and powered up the pi and it worked perfect. I am sitting about 50cm from the pi and have only heard the fan once when watching videos for about 1hr on youtube, apart from that it is so quiet. looking forward to coding it and setting it to automatically come on etc. Great product A+++”
“Bought the shim after originally going with the heat sink. The heat sink worked well but it’s got nothing on the fan shim!
This tiny little fan doesn’t look like it can do much, but it really can. It cools the pi significantly better than the heat sink, and using the recommended installer it doesn’t have to come on very often to do so at all.
Even when it does come on it’s barely audible when sitting next to it.
I can highly recommend the shim for all pi owners.
If I had to say there was any downside it would be with the pibow case. The shim doesn’t fit it very well and the button becomes very easy to break. Shame that there wasn’t some coordination with the two teams to account for this and cut a small notch in the pibow to account for it.”
Ahoy! Recent Pibows should have a notch in the top two layers to accommodate the Fan SHIM button - drop us a line at support@pimoroni.com if you need us to send you out some of the revised layers.
