First prototype of chilly hotend. met our expectations.

In other words, you’re copying @Shai_Schechter 's design minus the heater sleeve?
@ThantiK exactly what I was thinking
@ThantiK @Griffin_Paquette The heat sink model is based on Alpha hotends, alpha hotend had very small fan + heatsink, but here 40mm fan, so bigger fan.
I think @Shai_Schechter should be based on Alpha hotend as well.
