The AMD Radeon RX 6900 XT runs at an average of 69.7°C under load based on 3 community submissions. The hottest 10% of submissions report temperatures above 72°C, while the coolest 10% stay below 67°C. Idle temperatures average 43.3°C.
Flagship GPUs draw 300–600W and run 70–80°C at the GPU die under load with reference cooling. Memory junction temperatures can be 10–20°C higher; staying below 95°C on memory is the key safety target.

Based on 3 community submissions, the AMD Radeon RX 6900 XT runs at an average idle temperature of 43.3°C and an average load temperature of 69.7°C. Anything between 67°C and 72°C under load is within the typical range for this hardware.
The safe operating ceiling for flagship GPUs like the AMD Radeon RX 6900 XT is around 87°C under sustained load. 69.7°C is within the safe operating range. If you're exceeding 87°C, check thermal paste, cooler mounting, dust buildup, and case airflow.
For a 300W flagship GPU like the AMD Radeon RX 6900 XT, a quality 240mm AIO or a high-end dual-tower air cooler (Noctua NH-D15, Thermalright Phantom Spirit) is generally sufficient to keep load temperatures well within safe limits. Higher TDP variants (overclocked or PBO-enabled) benefit from 360mm AIO cooling.
