All temperatures listed are for CPUs running at default speeds with stock coolers. To give you a better understanding of Intel and AMD CPU operating temps, I have included their temperatures at different usage levels:

Idle Temperature - Computer idling at Windows desktop (no open windows or programs)

Normal Temperature - Computer during heavy use (gaming, video editing, virtualization etc)

Max Temperature - Highest safe CPU temperature recommended by Intel or AMD

Most CPUs will begin to throttle (lower its clock speed to cut down heat) once they hit 95 to 105C. If temperatures rise further, the CPU will shut itself down to avoid permanent damage.

Other Factors That Affect Your CPU Temperature Range

Even with default clock speeds and stock coolers, there are still other factors that will affect your normal CPU temperature:

Room Temperature

Ambient room temperatures can affect CPU temps by 5 to 10C. As a rough gauge, 1C rise in room temperature = 1 to 1.5C rise in CPU temps. That's why experienced hardware reviewers and overclockers will factor in their ambient room temperature when taking temperature readings.

Computer Case Cooling

A CPU can run 8 to 10C cooler in a spacious computer case with excellent ventilation vs a small, cramped case filled with dust.

CPU Build Quality

Due to their complex manufacturing process, even CPUs of the same model and batch can have notable differences in quality. While defective CPUs are discarded and inferior ones are rebadged, there is still a quality difference in those that make it past factory inspections.

Getting a high quality CPU from a store is a matter of luck (which is why overclockers get so excited when they chance upon a CPU of exceptional quality). All things being equal, a high quality CPU will run cooler and overclock better than a typical sample.

You need to know which numbers correspond to which TMPIN readings for your specific motherboard. Idle temps are also irrelevant unless you have a CPU mounting, paste, or fan problem.

I thought he meant "WHICH CPU TEMPERATURE SHOULD I PAY ATTENTION TOO?" as in him asking what temperature for the CPU to pay attention (High-Low). I hope you saying "That's completely wrong" and downvoting me was because I misunderstood his question, and not that you think my information is false.

That's comfortable for idle. If it's in the high 40s - 50s during idle or 60s-70s during normal load (YouTube, etc. Not gaming or anything) then you should be worried. If you aren't constantly at 80c that's a problem. 50s-70s are fine, however.

Downvote because all of the temps listed are arbitrary and not actually based on TJ max. It's misinformation. For instance, Haswell has a TJ max (thermal junction max, at which point the CPU will throttle) temp of 100C, not 72C.

I did not include the early statement on my post because I just thought it was not 100% necessary for a simple question. I have edited now.

Whcih one should i pay attention too?

'CPU 0' temperature

Or 'CPU' temperature (ItE IT8721F)
