I installed proxmox 7.3.4 on Dell Precision Workstation T7810. Without running any VMs, I noticed high cpu temp and noisy fans. Not sure what I am missing

Code:

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): n

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): ^C

Modern CPUs should reach 80 or 90 degrees or the automatic overclocking is not working or the cooling is needlessly expensive.
On an eight year old system it could be a fan failing or a dust build up inside the system, causing the high temperature and/or noise.
What would you consider a normal temperature and have you tested it with anything other than Proxmox?
