K8200 Nordic Chill Ultimate Cooling

I invented this cooler after having tried just about everything else. This unit will, when installed correctly, cool the PTFE part of the extruder, as well as making a swirling cooling effect on the piece you are making. It accommodates all fans, all sides and can easily be modified.

I use a setup with a single 70mm fan that never goes over 40%. This keeps everything cool, and keeps the noise level down when printing. Have not tried with other fans, but see no reason why it will not work.
