For those interested in BlueMacyver "built for ABS", unless you install the MKS Gen L V1.0 board as listed above, as shipped Ender 3's only have the circuit board fan running when the parts cooler fan is running and I believe most print without the parts cooler fan to cut down on warping.
Yes, you could print without the MKS Gen L, but you won't have as much success. The original ender3 controller board is junk and the single power supply isn't enough. On a long enough time line the power supply breaks. The parts fans do need to be dealt with though, you are right, static air is best- zero air movement. ABS is a very aggravating material to use and getting the environment just right is a must.
