Tech & auto temperature guides

Safe CPU and GPU temperatures, engine and tire temperatures, and sensor (PT100, thermocouple) conversions. Every tool below is free, works instantly in your browser and explains the formula behind the result.

Electronics and engines have safe operating temperatures, and staying inside them prevents throttling, wear and breakdowns. These guides explain what is normal for a computer processor and graphics card, a car engine, coolant, oil and transmission, how tire pressure changes with the weather, and how engineers convert PT100 resistance and thermocouple voltage readings into temperature.
