SOLVED [3.2-RC1] Hotend heater fault with fan on

Not sure if this is already known, but I think I have encountered a bug. On the first couple layers of a small object, the temperature setpoint changes, and the fan turns on to 100%, according to my slicer settings. However, the hotend struggles to keep up, and faults with "temperature rising too slowly". I do have a pretty powerful fan, but I'm also using a block sock. This is with a v6 hotend. I did tune with the new algorithm using
M303 T0 S245, which did activate the fan.

Have you saved the PID tune via M500? Can you Post the confit override.g? There was a small Bug where a space was missing
Trying to increase the temp while also turning on the cooling fan is a pretty good way to trip the protection.
If possible, stagger the fan coming on until after the temp change.
