ulimit can change the number of process on Linux. One of the features is to lower the CPU loading with it when you have a low end CPU. The lower the CPU loading the lower the CPU temperature.
sudo nano /etc/security/limits.conf
Append the following lines at the end of the file.
* soft nproc 10240
root soft nproc 10240
You can replace "10240" up to "65535".
That's all! See you.
