The other day, I received a parcel with a radiator and cooler from AliExpress
for the Milk-V Jupiter motherboard. I installed it, booted the system, running a build from the llama.cpp source code for load CPU.
I’m checking temperature sudo nvme smart-log /dev/nvme0 | grep ‘^temperature’ && sensors . Finally, at temperatures above 55 degrees Celsius, the cooler deigns to turn on.
Than i’m checking with
When running the build on 8 cores, the frequency is still 1600, instead of the stated 1800 with the fan on.
This raises the question of how to fix this issue. Why doesn’t the processor frequency change as stated, and how can I fix this?
