Part cooling and stringing

So something weird I've discovered and would be keen to find out whats going on…

I was doing a print the other day and found that all the stringing that I had been battling to get rid of has disappeared. Like none at all.

So I ran a test – printed one retraction test with cooling and one without any cooling at all using eSun PLA+.

On the part with cooling – some very fine wispy stringing happening all throughout the poles.

On the part with no cooling – no stringing at all! The perfect print as it were.

Anyone have any idea whats going on? I can't figure out whats going on considering what I've read about cooling and stringing…
