Whats the best temp for your CPU?

The maximum supported temperature varies from processor to processor. Most of the free monitoring software mentioned above lists the information as “Tj. Max.” That stands for the temperature junction, or the highest operating temperature of the hardware. If you don’t see the information for some reason, search the CPU World website for your CPU’s model number to find the information. Every program listed above displays your processor’s model number, so it’s easy to find.
But that’s the maximum temperature—the point at which your processor freaks out and shuts down to avoid damage. Running anywhere near that hot regularly is bad for the long-term life of your hardware. Instead, follow this general rule of thumb regarding CPU temperatures under load.
- Under 60° C: You’re running great!
- 60° C to 70° C: Still running fine, but getting a bit warmer. Consider cleaning the dust out of your PC if CPU temperatures continue to creep up over time.
- 70° C to 80° C: This is hotter than you want to run unless you’re pushing an overclock. If you’re not, definitely check to make sure your fans are working and there aren’t dust bunnies clogging up your system’s airflow.
- 80° C to 90° C: Now we’re getting too hot for long-term comfort. Check your hardware for broken fans or dust build-up, and if you’re overclocking, dial back your settings—especially the voltage if you’ve tweaked it. One notable exception: We sometimes see more powerful laptop processors hit the low 80s during gaming sessions when plugged in, at which point they start throttling back performance. This is expected, but if temperatures cross 85° C, be concerned.
- Over 90° C: Danger, Will Robinson!
