After a fashion

A friend who purchased one has had to spend the same amount again on finned heatsinks that cover the whole of the base plus all area that is free of sockets on the top as well as two micro-fans on top. It's now stopped overheating - during mid-season weather. Situation in summer remains to be seen.

As a result, the plastic case is no longer usable. Aluminium cases are available, but don't provide direct heat-sinking and might not be an effective solution.

Not a low cost solution and could still require careful placement of the device to get adequate airflow.

There is a firmware update for the Raspberry Pi 4B that lowers the temp a few degrees. I've found a few links but I have not located the Official Raspberry Pi fix. There is a concern about USB 3 speed slow-downs after applying the new firmware.

My Raspi 4B is not overheating or throttling that I've noticed. But I am not stressing it or using for anything heavy duty. I'll run some tests sometime soon.

I think this is the official version:

Came across this as I was looking for something else:

RPI4: NOW OVERCLOCKED, NET-BOOTED, AND POWER-SIPPING
https://hackaday.com/2019/10/30/rpi4-no ... r-sipping/

Full disclosure: I have not tried this yet.

My pi4 does not overheat and works perfectly well. Waiting for ipfire release that will work on it.

Until the mainline Kernel support it and we are on this version it will not work. So this can take long time...

Initial debug support is planned for mainline kernel 5.4 but this will not include Ethernet or USB3 support so it is still not useable for IPFire...

I follow this thread from the beginning and just ordered a pi 4 (black friday).

Instead of waiting for native support by the kernel, why can't we grap the kernel code 4.19 for the raspberry pi 4 and build ipfire with it?

How do other distributions (that are made for the pi 4) handle that problem?

5.4 LTS is out. Maybe it's "easy" to implement the missing stuff? Otherwise we'll need to wait another year untill the next LTS kernel version :-\ .

I only mention this because Arne.F says it will be awhile, hope it's ok.
I do have a working arm64 version of Smoothwall for the p4 for anyone interested.
