I am designing a fan mount for the CR-10S printer to hold the E3D All-metal v6 HotEnd and BLTouch sensor.
The CR-10S printer has two fans.
One on the front:
and another one on the right:
I need to know what the two fans are actually cooling in order to make a perfect mount.
When powered on, the front fan seems to be on 100 percent of the time. The right fan can only be on via gcode when printing.
I removed the fan mount to study it and it looks like the front fan is cooling the hotend heat sink.
The right fan is attached to the mount and there no hole there to let the air from the fan go through. It seems to be cooling the metal it is bolted to and that doesn't make sense.
Am I correct about the front fan? What's the right fan cooling?
