Maximum operating temperature for the CPU is specified in the documentation.
The maximum operating temperatures for these CPUs are typically around 85°C to 90°C. The CPU case temperature usually stays within a similar range, while the CPU junction temperature can reach up to 100°C under heavy load. For extended gaming sessions, aim for a sustained temperature between 60°C and 70°C for optimal performance.
case temperature refers to the heat from the top of the CPU's IHS, the part with the label. It’s not very helpful when the cooler is on top. Junction temperature comes from sensors and shows actual readings. Most CPUs and GPUs use several sensors; usually the one showing the highest value is used. If you're not overclocking, just keep it under the maximum junction temp—Intel models generally stay between 95°C to 105°C. Going below 70°C during overclocking can help you go further, but the difference between 60°C and 90°C is minimal otherwise.
For Intel CPUs, the official maximum operating temperature is typically around 115°C, the official case temperature is often specified by the manufacturer (usually 70-80°C), the junction temperature should not exceed 85-90°C, and ideal CPU temperatures range from 30°C to 60°C under normal conditions. Official reference links can be found on Intel's website or in their technical documentation.
By checking the connection, you'll notice Intel doesn't share it publicly, but based on past observations, we can estimate it will cost around 95 to 105 cents, similar to what @Jurrunio discussed for TjMax.
Check Intel's official site for the CPU's dedicated page; they list the Tcase details easily. Search engines also work well. The junction point is where thermal throttling starts—both models should stay at around 100°C. They don't officially confirm lower temps, so you're either relying on my info or risking missing it. I've mentioned the recommended temperature range before. Intel looks at every temp below the ideal junction and says they're fairly accurate, though sensors become unreliable under 0°C.
You've been managing your CPU temperature well over the past five years. Maintaining a case temperature around 71°C while keeping the CPU at 61°C is a solid approach, especially given the junction temperature reaching 100°C. Running the CPU at 90°C might be possible if you adjust other factors like cooling or workload. Earlier advice to keep both chips within ambient and 75-80°C was correct—temperature spikes can affect performance and longevity.
Aim for a steady 90 volts, even with a bit of overvoltage. The CPU will signal when it’s satisfied.
Have you considered pushing past 3.2 GHz? I recall testing 3.3 or 3.4 GHz and noticed performance drops while gaming. It’s been a while since I revisited those settings. The page you referenced lists turbo speeds for different core counts, but I’m still unsure if the issue was related to artifacts or something else. My current setup is the i5-6402P from CPU World, which has an 8-pin power connector and a heatsink on the left side but not near the top. During gaming sessions, my CPU temperature stays very low—around 30-40W, essentially none. I’ve never exceeded 61°C.
case temp limit does not refer to the CPU's actual case temperature, that's not the word "limit" means. Case temperature higher than the actual temperature either since it's further away from the hotspot, i.e. where the heat is generated. eh you're still limited by Intel's multiplier lock and more, but sure it has thermal room to go beyond 3.2GHz. Yes 75-80 is where people usually aim because pushing to the limit makes them comfortable.
