Yes I have a similar problem where the fans come on inconveniently because of Intel Turbo Boost (for a matter of seconds).
Is it possible for better support of the XPS fan controller? - There is only an OFF/Medium (2800rpm)/High (4200rpm) settings available. The medium speed is slightly too fast.
Also, changing the fan speeds will cause a high latency (system hang of about 1 second)
Thanks
EDIT - Been reading some other posts - I’m guessing that the controller is not fully compatible at the moment being EC
