Part cooling fan always 100% after V2 update

Bambu Lab Software Bambu Studio

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.

I have opened a support ticket on the Bambulab website.
The problem could be solved by replacing the extruder connection board and the front housing assembly. Both parts were sent to me under the terms of the warranty.
