How to fixCPU-PACKAGE-TEMP-LIMIT

CPU Package temperature limit reached

What this error means

CPU Package temperature limit reached ranks as a high-severity processor (CPU) issue in our database. The CPU package temperature has reached or exceeded the manufacturer's maximum junction temperature (Tjmax), typically 100°C for Intel and 95°C for AMD. The processor initiates emergency thermal shutdown to prevent permanent silicon degradation. This is different from throttling — the system halts completely. Common triggers are insufficient CPU cooler TDP rating and blocked airflow in case. The steps below are ordered to resolve this efficiently.

Before you begin

Save open work and back up important files. Note any recent driver or hardware changes. If Windows cannot start, use the startup guide first.
