Normal temperatures for desktop CPU and motherboard
Can someone help me understand what a normal temperature range would be for current desktops with Intel CPUs would be? It was my impression that anything over 70 C was too hot, but I've been challenged about that, and would like to understand this better. Personally I have an Inspiron 660 desktop with an I5-3330 3.0 GHz CPU, and I know these numbers can vary from one CPU and motherboard to another, but I don't want to tell folks their desktop is too hot when it's not. I do a lot of volunteer work locally and on some of the forums. Any info from your best recollection welcome, but a link would be most helpful! TIA

There's no such thing as normal in that sense because cooling is passive. cpu-z and other programs do not always give proper readings. Intel® Processors have built-in thermal protection. If the processor gets too hot, the built-in protection shuts down the processor.

TCASE is the max Temp so for this specific cpu its 67.4°C

These terms are related to processor temperature for desktop and mobile systems based on Intel® Processors. To allow optimal system operation and long-term reliability, the processor must not exceed the maximum case temperature specifications as defined by the applicable thermal profile.
Tcase is the temperature measurement using a thermocouple embedded in the center of the heat spreader. This initial measurement is done at the factory. Post-manufacturing, Tcase is calibrated by the BIOS, through a reading delivered by a diode between and below the cores.
Tjunction is synonymous with core temperatures, and calculated based on the output from the Digital Thermal Sensor (DTS) using the formula Tjunction = (Tjunction Max – DTS output).
Intel provides a diode between and below the cores with a reading calibrated by the BIOS. This reading can vary greatly between BIOS versions and BIOS vendors.

Some AMD cpu's go up in smoke literally.
