I was reading your thread and it captured my attention immediately, I understand that you are monitoring the temperatures of your set up and I am very pleased to read that you take care of your machine’s health and performance
Based on the Specs of your units let me point the following:
Your Intel® Core™ i3-8100 is (based on your description and screenshots) reaching peak temperatures up to 74 °C. This is actually fine considering that the CPU’s max temperature will be 100°C.
Here you will find all the specs for your current CPU:
Your previous Processor (Intel® Xeon® Processor X5470) never goes above 60°C -65°C with a similar cooling solution. The actual reason why is because the maximum temperature for this unit is 63°C and the unit is intended to perform on lower heat ranges than your Core™ i3-8100.
Here you will find all the specs of your X5470 CPU:
