If you don't have the option of mounting a fan..
1) Remove any and all enclosures
2) Said desk fan and PID can help, but it is only a hail mary
3) Print a tall skirt as far away from the outer perimeter of the print as possible
4) With suggested 1-3 performed, slow your speed down slightly.

PLA needs longer times to cool, so keep this in mind first and foremost!

If you don't want to wire one up to your machine, a desk fan blowing in the print area will work as a temporary solution, but you will likely have to re-run PID autotune with the fan blowing on everything.

A layer fan can help a lot as well.  Of course, not my idea... another pearl from the community.

I usually print everything at 15% infill but you can try it at 20-30% and it should be solid enough... I would also leave the front and top door open to allow more cool air to enter the print area.

You can try putting a fan over the print area, or try printing multiple parts at one time to give time for cooling.

I am consistently getting melted layers when I try to print this chess figure at the following settings:

Temp: 190
Bed: 45
Layer: 0.2mm
Infill: 75%

Played with speeds, same results. Looks like as it progresses to the higher layers, they start melting and sinking.

Any advice?
