Lakester, what do you use for a print cooler? It could be that you need one with a bit more oomph to it. So many of the ones with a shroud in front of an axial fan just don't provide all that much airflow. Backpressure from the shroud just causes air to leak past the edges of the fan blades.

But yeah, use of a print cooler is certainly one of those YMMV things.

I use the extended version of the clough42 shroud combined with a not commonly used (but easy to install) HE fan shroud that assists with reversing the HE cooling flow from the stock setup.

Hopefully..., the pic has uploaded correctly...

One other comment: yah..., the exit end of the shroud is some distance from the nozzle..., but it seems to be fairly effective in that turning on the fan at 100% causes an almost immediate 6C drop in HE temp...., which the system eventually compensates for. Heh..., since I don't like to leave the HE just cooking the filament at the end of a print job, my post-job gcode turns the fan on to accelerate HE cooling. Very effective!
