That must be CentOS then. No virtualisation. It’s running on a Supermicro X7SPA-D525-HF, bare metal. This is a passively cooled system with an Atom processor.
There is clearly something wrong with your cooling!
Even the mainboard is passive cooled you need at least a good airflow with fans inside the enclosure.
See here and other google searches.

Sure the Installation and Update auf VitalPBX uses the CPU. This is normal. Even after hours of 100% CPU Load your system should not get too hot.
