I'd suggest not suggesting anything at all to everybody if you have no knowledge of nature of the issue.
It has happened before that a beta firmware link was removed. It's part of the beta process.
If Fractal Audio thought that any of the beta versions could possibly harm an unit, there would be a warning issued. That hasn't happened.
The fact that the fan now runs more often, will probably be fixed. At the very least it's reassuring that you know that the fan is working.
Such things are designed to run for tens of years.
