Part cooling fan always 100% after V2 update

Hi,
I just updated to 2.0.1.50 and noticed that the printers (P1P and P1S) were both much louder. After watching a few prints it seems the part cooling fan is running 100% all the time.

I haven’t changed anything before or after the update. P1S door closed but lid off, P1P as is. Using Bambu PLA or Generic (elegoo) PLA.

I use the standard Bambu PLA or Generic filament profiles.

I reverted back to 1.10.2.76 and its still the same.

Prior to updating to version 2 I could hear the printers running and the part cooling fan would ramp up and down depending on overhang/bridging etc.

I couldn’t tell what fan speeds they were running at before as its not something I had ever tweaked but they were definite;y not running at 100% all the time before.

Has anyone experienced similar?

Does anyone have any ideas on how I can get back to the prior behaviour?

Thanks in advance.
