Testing Sunon 30x30x15 extruder fan

I was looking through the digikey fans and saw a pretty nice looking 30x30x15 fan from sunon which has a roughly equivalent airflow compared to the stock fan (6cfm), but with a lower noise - likely due to a combination of their magnetic bearing technology and the additional thickness of the fan.

The fan is *almost* a drop in replacement for the stock 30x30x10 fan. The only problem is that with standard hex head m3 screws, the head of the screw hits against the z axis threaded rod and prevents the x-carriage from hitting the endstop. I solved this by switching to a pan head screw for the screw on that side (just the lower screw, the upper corner doesn't have a screw hole), which leaves enough clearance for everything to work.

My existing stock fan was on the fritz anyway, so I just cut the leads on it and soldered them onto the bare leads of the new fan, and wrapped the joints in some tape.

I turned on the printer and bumped the temp up... and ahhhh. blessed near-silence. It's still audible, but *much* quieter than the stock fan.

My only concern is ensuring that it is providing enough airflow. But I did some side-by-side 250-to-0 tests on it and my other stock prusa, and I think it is actually providing better cooling, because it cooled down more quickly than my other prusa with the stock fan.

I haven't actually printed with it much yet, so we'll see if I get any jams or anything like that.
