Hello guys, I just had issues with a print regarding overhangs. When I printed it with the right nozzle the print had dents and scars. And with the left nozzle it was flawless. The left nozzle gets way more cooling of the part cooling fan than the right nozzle, I hope only my printer has this problem and this is not intended.
Here is a image with right nozze print:
Here is a image with left nozzle print:
Here is a paper test of the cooling of both nozzles

Please check your printers if you have the same issue
As far as I can tell mine is really only blowing air on the left nozzle when I manually turn on part Cooling. I don’t know what is going on

Yeah it really feels like only the left nozzle gets air. 
I don’t get why nobody talks about this or has found out about this
Nice find! I’ve mostly been doing high temp prints with very low or no part cooling fans.
This will require greater attention to the part’s positioning or nozzle selection when maximum cooling is necessary.
You know what. I can’t remember if I did this or not. Did you try selecting the right nozzle when you tested with the paper test. I don’t know if they have something to divert the air more to one nozzle or the other when a specific one is active. I’m in a larger print right now so I cant test.
Could it be that if the part is leaning right, the right nozzle is better, visa versa?
I’ve tried it, yes. But it didn’t change anything. I have linked a video in the post I made there you can also see it. Did you try it yourself already?
Yes i did. Same results. High air flow on left, low air flow on right
yes, if you put a glass of water under the toolhead you would find that the center of wind pressure is actually under the left nozzle. However I would argue that you still get better than normal / X1C level of cooling for right hotend.
