Is there a addon to reduce clock speed/power consumption? My pi is getting 62°C hot… never got it that hot with rasperian. I only get the temperature in hw diagrams, no clock speed etc.
Also I wonder that there is not network information except red on the main page.
my RPi4B with only raspberry pi lite is running near 50ºC.
my RPi4B with IPFire CU 159 is running near 56ºC.
is your RPi4B in a case? Does it have a heatsink?
I know the RPi4B do run hot and there were many complaints when they first arrived. I don’t know if this will help but take a look at:
It may not work with a raspberry pi.
I looked up “under clocking”. You’ll need to do more research but I found stuff like this:
I got an standard aluminium case with heatspreader on cpu, RAM und USB controller (all thermal glue).
As far as I know this is for x86 CPUs only.
Hi Jon,
I just installed the addon and was too lazy for the ssh interface and therefore looking for “clocking” but I can’t find it. Am I blind?
Cheers Terry
from what I read yesterday it doesn’t look like an RPi uses cpufreq. And under clocking seems to be frowned upon.
There are references to the RPi4B having the ability to auto-slow (under clock) when the CPU senses high temp. But I have no idea if this is done in software (i.e., Raspberry Lite/Desktop) or in firmware. And I don’t know if IPFire has anything as part of its software.
Sorry - this is beyond my skill set!
It did the same for me. Since it doesn’t work there is no WebGUI interface.
EDIT:
FYI - The command I used when cpufreq is installed was
cpufreq-info
The cpufreq-utils is availbale for am since core159.
The initskript will change the default governor from performance (without installed cpufreq-utils) to ondemand. So have you tested the temperatures after installing cpufreq-utils and a reboot?
for me it stay the same (maybe goes up a little)
The break in graph is the reboot.
Not sure if this helps but I see these messages with cpufreq-info:

Yes. It varries between 58 up to 62 degrees.
I get exactly the same.
Any progress / news here? It still won’t run any governor except the default value performace.
The governor is not the problem. Looks there is no cpufreq driver avaliable for the broadcom SoC on the RPi4 in the mainline kernel or it is not enabled in the IPFire kernel config. Without this you cannot set the frequency st all.
I’m by no means an expert on this, and have NOT run ipfire on a Pi before, but you can research the “arm_freq” key value pair in the Pi’s config.txt file. You can use this for overclocking, but presumably also underclocking the max frequency of the Pi.
