The normal GPU temperature depends on the model of the GPU and the load it is under. Here are some general guidelines:

• Idle: 30° to 45° C (86° to 113° F)
• Gaming: 60° to 85° C (140° to 185° F)
• GPU Rendering: 70° to 80° C (158° F to 176° F)
• Maximum temperature: The upper limit of Nvidia GPUs is 95 to 100 °C while it is 90 to 100 °C for AMD GPUs

Its important to note that different GPUs have different max temperature tolerances, and some models may run hotter than others. However, maintaining temperatures within the ranges listed above should keep your GPU operating at its maximum potential. If your GPU is consistently running above these temperatures, it may be overheating and you should take steps to lower the temperature, such as improving ventilation, reducing overclocking, or upgrading your cooling system.
