Rostock Mini Fan Duct

I suggest you try setting your cooling to 25% for extruder cooling (at 100% my extruder couldn't maintain 185 C!). It can cool a print job if you run it at 100%. See a video of me printing my C9 bulb cooling required test part here:

Yes, it cools my test print running at 100%, but doesn't have a lot of extra capacity (at the very top of the bulb where it gets super small the plastic was looking visibly gooey, but it held together)
You can see it in action here:
so is the air enough to cool the print?
My current problem with a side mounted fan is that you can only cool one side of the print.
I'm using a MakerGear "V3 GrooveMount". Brian's printed hot-end mount fit the top perfectly, so It's probably very similar to what he is using, or at least uses the same top circle size. Instead of laser cutting a piece of plywood to hold it, I bought a "wooden mounting piece" for "Wades" extruder, traced around it with a pencil, and cut the extra pieces of with a bandsaw. I also had to drill out two holes to match the platform.

Use four M3 screws (I used 16mm length) to mount it to the platform (from the bottom) via the four extra holes. Use four M2.5 screws (I used 16mm length) to mount a 40mm fan to the top.
