Double fan cooling for Prusa i3 MK2 and MK2S

Since purchase of printer I had problems with steeper overhangs, sometimes it started to hit PINDA probe. I reworked newest B3 version nozzle-fan from MK3 but still didn't solved overhang problem. So I went to e3d-online shop and bought additional fan and V6 Silicone Socks and reworked MK3 B3 nozzle-fan design for dual fan setup.
Tested on temperature tower, with temperatures ranging from 190 to 220 degrees at 0.2mm height.
In photos left temp tower is stock MK2, on right dual fan setup.
