In Rasmusen case, after complete troubleshooting, the PSU was replaced by the DELL-Cares agents.
Our new XPS 8950 running smoothly. Unfortunately, there is an obvious loud noise coming from one of the power supply (PSU) fans. To be sure, all other fans are running smoothly including the RTX GPU fans. When looking at the PSU installed in the case, the left fan is definitely emitting a loud sound almost as if it is rubbing against something. I have not attempted to remove the PSU or manipulate the fan other than to confirm it has issues. Hoping this can be easily resolved as its still under warranty?  Not sure if this is common or easily resolved.
