I designed this but don’t have an Ace to try it on.
Anyone interested in a fitup trial?
Thanks for the effort. But what’s the point? The fan on the SV06 Plus ACE runs at 70% and only uses 100% for overhangs. The cooling is very good, but loud. I don’t see any benefit in two fans.
A user posted last week asking if it was possible. He had an issue with overhangs.
Looking at Autodesk’s overhang test here, I’m quite impressed. However, the noise level isn’t particularly pleasant.
Here is the post:
Main point was to exercise my cad skills
Secondary point - nozzle visibility
If it were for personal consumption it would have only had a single fan motor. 2-50x15 is borderline ridiculous IMO.
There was also another thread where someone was complaining about overhangs with a Volcano nozzle. Sovol’s design has the fan unusually high with the airflow downward. My assumption was the steep angle of the Volcano nozzle resulted in the tip being “shrouded” by the heater sock and the hex on the nozzle. A more typical horizontal airflow might overcome that.

Nozzle visibility is very important, for first layers specially so.
One 5015 could be enough, test should show, but even more important is possibility to move the whole thing about 2-3mm up and back down in case shorter or longer nozzle is used.
Project look very promising, wish you the best of luck.
Yes. The Volkano nozzle is apparently positioned very close to the fan nozzle. This could have adverse effects on the airflow. So far, I’ve only experimented with the K1 nozzle. It’s only slightly shorter than the Sovol nozzle. So, it had no noticeable effect. Let’s see if there’s an improvement. I just don’t want to install the second noisy brother. The noise is enough for me. 
Never thought about it but Klipper allows you to set max fan PWM. I assume then gcode fan speeds are scaled against that setting.
Multiple big fans might be able to deliver the same airflow with less noise.
