It indeed looks like a cooling problem since the problem is the worst at the overhang. Altough there are a couple of things that could also cause these crappy kind of prints. I would try to clean your nozzle and level your bed just to make sure before you start ordering new fans
Is it also related to the dirty nozzle or bed leveling?
I'd say you can print at a lower temperature also. This leaves the material cooler to start with.
Possibly when you go lower you might also need to go a little slower

Yes, I tried lower the temperature to 200 with a lower speed. But the effect is not very satisfied. I also tried lower the flow, which cannot solve this issue either and introduce the under extrusion. My understanding is that the following parameter can print most models:
Later height 0.1mm
Temp:210
Speed:90
Flow 100%
But now it cannot work for me.
Can you feel the air flow from the fan? Is it strong? Are the blades dusty?
What if you slow down to 40 mm/sec and 200?
