You might get lucky. There seem to be some users not affected. Did a poll long ago and there were some people that said they had no issue..
At least from the people in this thread who had a replacement nobody had an improvement IIRC. Only the custom builds with different PSUs alltogether.
Framework seems to aknowledge that there is an issue and that they are investigating / working on it. The description in their deep-dive post on the PSU and how they market the machine as silent does not reflect reality. Them being completely silent is very frustrating, but given their track record with issues and fixing them in the end I’m hopeful we’ll get a solution some day.
Running the APU at a minimum speed is not ideal, but a good enough temporary workaround for me. At least currently in the winter months - we’ll see what summer brings
