Well about 6 months after a started building I have finally completed a new watercooled PC. When I managed to get a Gigabyte RTX 3090 with the integrated waterblock I found that decent PSUs were hard to come by so I bought a cheap 750W PSU to get me started. It was noisy at idle and noisier at load, but worst of all I got fairly bad coil whine with 3DMark and the Bright Memory Infinite RT benchmark. I pulled the PSU and put it on top of the case so that I could easier tell where the whine was coming from. My conclusion was that it was mostly from the cheap PSU but the RTX 3090 was whining too.
After a long wait I got a new PSU yesterday. I hope I can now claim that I have minimised the noise contribution from the PSU because it is the Corsair AX1600i. Indeed it is silent, but the RTX 3090 is still whining during the benchmarks. I have checked some reviews and it seems that this GPU and its RTX 3080 brother have whined to reviewers so I guess I have to be realistic on my expectations. Whilst I'll accept requesting RMA if I have to, the current issue with availability and the risk that a replacement would whine too leads me to consider alternatives first.
So can folks advise me on what are the steps to try to reduce coil whine? Does "whine-soaking" a GPU with a benchmark actually help? What about reducing boost clock or under-volting?
