The safe temperature limit for GPUs can differ based on the manufacturer and model, usually falling between 90°C and 110°C. For instance, NVIDIA and AMD have their maximums set at 93°C and 110°C, respectively. Although these figures represent the highest acceptable temperatures, keeping your GPU cooler, ideally between 65°C and 85°C, is best for performance and durability. Elements like room temperature, dust accumulation, and the effectiveness of your cooling system can greatly influence how hot your GPU gets.
