Sudden Terrible Bridging

My MK3s is suddenly printing terrible bridges and overhangs.  I have printed new fan shrouds in FDM and hi-temp SLA material but the issue persist.  It happens on all filament types, I've tested two rolls of PLA and two rolls of PETG. Oddly, the cooling seems OK on the benchy, not perfect but certainly better than the bridging would indicate.  When I have the part can on I can feel good airflow around the nozzle.

This also persist across slicers.  Images show the bridging and the cooling.  Any ideas?

fan spinning but cooling is poor, issue re appears 3 ish weeks after changing the fan for a new one

Did you ever find an issue for this?

I had the same poor bridging all of a sudden and the front fan is still spinning thoughout the print, passes self test and is set to 255.

I changed the fan for a new one and it was fine again but now less than a month after changing the colling seems bad, bridging looks like your benchy it sags and gyroid infill sags when going from vertical to horizontal. Top solid layers over infill also sagging alot.
