The "standard" for normal room temperature is 22°C or 72°C, so your ambient is relatively close. Members write into our Forums who live in climatic environments anywhere from the Arctic Circle to the Equator, so
indoor ambient temperature might be anywhere from 10°C (50°F) to 40°C (104°F), which can be a HUGE variable.
Keep in mind that when watching YouTube videos or reading through temperature threads on various Forums, users who are "poorly informed" tend to fling load and idle temperature numbers around like Gorilla poo in a cage.
Processor temperatures involve 3 major variables; environment, hardware and software.
• Is what you're referring to as "idle" really
idle?
Idle means
minimal activity, which is only 1 or 2% CPU Utilization in Windows Task Manager. Idle does NOT mean a light workload, such as typing in the Forum while watching a YouTube with 10 tabs open with numerous unnecessary processes, services, startup programs and "tray trash" left over from software installs running in the background.
• You mentioned "other heavy loads" ... such as what?
Although "Throttle" temperature for the 7700K is 100°C, here's the nominal operating range for Core temperature:
Core temperatures above 85°C are not recommended.
Core temperatures below 80°C are ideal.
Gaming generally averages around 55°C, yet can range from 40 to 70°C, depending on how a particular game title allocates CPU / GPU workloads, as well as differences in overall cooling performance and ambient temperature.
