Jargon buster

Plain-language definitions for the technical terms used above.

passive heatsink: A heatsink is a piece of metal shaped to draw heat away from a hot component, and passive means it works without a fan. This matters because it can keep a processor cooler and quieter, but the case itself may become hot during use.

What customers say

Customers agree the case lowers Raspberry Pi 4 temperatures and is well made. Most found it easy to fit, but reviewers reported fragile or unusable thermal pads, and one found the camera and display connectors hard to access once assembled.

I have now used several of these passive coolers from Little Bird Electronics. I use them with Raspberry Pi's and deploy them in my home network, such as DNS servers and Ad blocking software. They work perfectly.

Looks like a great product

Looks like a great product. It came quickly. Online instructions are a little outdated as there is one additional thermal tape piece; but it’s simple to figure out where it should go by looking at the top aluminium piece. Happy customer.

Product is great

Great little passive cooling device

13 Oct 2024

Applied this to the new Raspberry Pi 4 and it works a treat! No fans to wear out and it does the job. the key chips are connected back to the aluminium heat sink via heat-conductive foam, so the chips should work just fine for most indoor applications, which is my situation.

Does it's job well

11 Oct 2024

The good: It's solid and a very complete package. Looks pretty nice too. There are cutouts for the display and camera connectors. The bad: You can't actually attach cables to the camera and display connectors once the top cover is in place. You need to do that beforehand. I'm sure you're thinking "Just unscrew the cover", but there's adhesive thermal tape under it so I am not sure what's going to happen there.

Reduced CPU temperature by around 20 degrees C

2 Mar 2020

My Raspberry PI 4 in the standard case was seeing CPU temperatures of between 65 and 75 degrees C (and sometimes up to 80 degrees C) which I was concerned about. I recently purchased one of these cases with the aim of moderating the high temperatures. I was pleased to find that the case reduced the operating temperatures by almost 20 degrees, and the CPU temperature now varies between approximately 45 and 55 degrees C. You can find a blog post about my experience with the case here: https://newadventuresinwi-fi.blogspot.com/2020/03/heatsink-case-for-raspberry-pi-4.html
