Is 95°C Normal for a Ryzen 5 9600X During a Stress Test?

The six-heat-pipe cooler should generally be suitable, especially if the CPU is running stock settings. If the processor reaches 95°C during games rather than only during an all-core stress test, check that the cooler's protective film was removed, the mounting pressure is even, the fan is spinning correctly, and the case has adequate airflow. Also check whether PBO or other automatic overclocking is enabled.

A stress test is specifically meant to drive the processor close to its limits, so seeing it reach the thermal target is not automatically a fault. If games and regular applications stay at reasonable temperatures, the system is probably working as intended.

Assuming you mean the Ryzen 5 9600X, 95°C during a heavy synthetic stress test can be normal. These tests push the CPU much harder than typical gaming or everyday workloads, and the processor is designed to boost until it reaches its temperature or power limit. The more useful number is the maximum temperature during normal use and whether the CPU is actually thermal-throttling.
