Delta Kossel Fan LED Hot End Combo

Even after adding LED strips to my delta towers, I wanted a little more light where the printing was actually happening. So after many iterations, I finally got a combination that works for both cooling and lighting.

I used two 4020S blower fans, that are driven from a PWM variable supply. Mainly because I can do a better job of deducing where the cooling will be required and how much, better than any firmware or slicer can.

The standard axial 40mm cooling fan keeps the hot end heat sink cool itself.

Note: I only use E3D V5 hot ends. V6's are significantly smaller in height, heat sink, heater block and won't fit in my mount at all.
