My latest experience with a noisy GPU fan turned into just such an opportunity. At idle, the GPU temperature hovered around 80 °C, clearly unhealthy no matter how modest its workload. Initially, it seemed perfect: the GPU temperature dropped significantly; hovering around 40 °C even under load. Solution Part 3: Automatically Adjust Fan Speed Based on TemperatureDS18B20 may seem like a mouthful, nor does it roll of the tongue easily. Solution Part 1 (manual fan replacement) immediately eliminated flickers, lowering the GPU’s idle temperature to around 35 °C and peak load temperature to 40 °C.
