The fan on my hybrid cooled GPU is not working. I have installed the proper drivers and tried 3 different hardware monitor apps plus the UEFI hardware monitor. The water pump seems to be working perfectly. It is running stable at almost 2 ghz, which is about 400mhz or so above its base clock rating.
I have run many different benchmarks on it and even under heavy load (DirectX12, 3440x1440resolution, etc.) for periods of up to 5 minutes, the temp gets no higher than 40 degrees Celsius. Benchmark scores are through the roof, as they should be. GTA V runs very smoothly at max settings minus frame scaling. If temps are so low with just liquid cooling and a dead fan, why does it need a fan at all? (the one on the GPU, not the radiator fan). Is this fan cooling some area of the GPU that for some reason needs to be air cooled, rather than liquid? Is it possible that something is over heating that isn't represented by a thermal sensor?
I guess I should mention that during tests such as "compute", like on PassMark Performance Test where it's an undulating fractal image, the GPU makes a noise that I could only describe as a very high-pitched, but fairly noticeable squeal. At first I thought it could be some capacitors or coils on the MB, which I guess it very well could be, as they supply a very large amount of power to the GPU. Especially since it is a 1080 ti. The reason I think it may be the GPU is that the sound seems to have a "rhythm" that almost exactly matches the movements on the screen. The weirdest thing is that when this started happening, I noticed an immediate improvement in benchmark scores. About 5-7% improvement. Sometimes it makes a shorter, but louder squeal when the computer is idling. I will try to make a video and upload it shortly. Should've had that ready, but give me 20 mins.
