Continuing with the thread hijack...
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.
