Hello, I have this problem with my GeForce GTX-750: the fan makes a loud noise every now and then even when the computer is not doing any graphics-intensive processing. This behaviour can be witnessed with and without AfterBurner installed with a custom fan-speed curve. The attached screenshots GPU-1 and GPU-2 show my (relevant) AfterBurner configuration. The fan should never drop its speed below 50% at any given temperature. The attached screenshot GPU-3 shows GPU-Z monitoring tab. As can be seen, the fan speed (%) value is 50% so it seems that AfterBurner is doing its work nicely, but the fan speed (rpm) value drops to zero every now and then, and then goes up to max causing the loud fan noise. The dropping in the RPM value is not mirrored in the % value of the fan speed value in GPU-Z. Running AfterBurner with or without admin rights makes no difference. I also tried three different versions of the GPU driver but nothing worked. This problem started around autumn 2019, and for more than a year, AfterBurner was perfect to solve this problem; but since about a month; it seems that using AfterBurner is not enough anymore to tame the loud noise. I also cleaned the GPU as thoroughly as I judged since I thought maybe temperature sensing is inhibited by dust/gunk. Any ideas? Many thanks, A.
