Thermal Throttle Calculator

Estimate CPU/GPU operating temperature and thermal throttle risk based on TDP, cooler rating, ambient temperature, and case airflow quality.

How to Use the Thermal Throttle Calculator

  1. Enter component TDP in watts.
  2. Enter your cooler's rated capacity in watts.
  3. Enter ambient room temperature.
  4. Select case airflow quality.
  5. Click Calculate to see estimated temperature and risk.

حالات الاستخدام

الصيغة

Estimated temp = Ambient + Airflow penalty + TDP × thermal resistance. Throttle risk based on junction temperature thresholds.

الأسئلة الشائعة

What temperature causes throttling?
Most modern CPUs throttle above 95°C (Tj Max). GPUs typically throttle at 83–90°C.
What is a good cooler for a 125W CPU?
A 150W+ rated air cooler or 240mm AIO liquid cooler is recommended for a 125W TDP CPU.
How does case airflow affect temps?
Poor airflow can add 10–20°C to component temperatures versus good airflow with proper intake/exhaust fans.
