Hello everyone,
I currently use the great app Macs Fan Control to override my iMac's default fan settings because I don't want it to reach CPU/GPU temperatures of 95 °C or higher (which I experienced with my iMac under heavy load and which seems to be "normal"). I have configured the single fan in the iMac to reach maximum RPM when CPU core 1 reaches 75 °C. As a result, the CPU and GPU don't exceed this temperature.
However, I asked myself what would happen in a scenario where almost entirely the GPU is active. It would be conceivable that the GPU would reach a critical temperature (eg. 100 °C or higher) because the single fan is relatively inactive because the CPU is not that warm. Likewise, if I would use the GPU sensor to control the single fan, a task that is very CPU intensive but not very GPU intensive could lead to an overheating of the CPU.
Since the app does not allow setting multiple conditions, the only truly safe method seems to be setting the fan to full RPM at all times, which would be noisy.
Am I overlooking something? Is there a better way?
