“These little aluminium heatsink cases are the business if you want to work a Raspberry Pi 4 hard with passive cooling - no noisy fans :)
They're available in a range of snazzy shades which makes it easy to visually identify them if you have a few of them.”
“These are the best-looking and most functional cases I could find, but there are a couple of things that could be improved:
1. There is no good way of mounting the case to a base plate or larger enclosure: I had to epoxy aluminium mounting ears onto the aluminium base. Heatsink also works better if stood off the surface a little.
2. There is no effective path for heat to the cooling fins on the base. A land for a heat pad pressing on the rear of the Pi PCB behind the main chip would improve this.
3. The Allen key provided was a sloppy fit requiring to be pushed to one side to bite.”
“I have tried various cases for my RPi 4s and this type is by far my favourite. My 1st RPi 4 was the original model which used to run hot. This type cured it and is compact and rugged. The only drawback is using HATs which can't (easily) be mounted; however, highly recommended.”
“Blimey, like a slab of solid aluminum, very impressed, passive cooling seems to make so much more sense to me! If you are not using the GPIO pins you'd be wise to run a bit of insulation tape over them or use a dedicated cover.”
