Hotend fan flow direction?
Hello all,
Just assembled my kit and all seems to be working well! I have only one question; which way should the hotend fan blow? Towards the hotend or suck air over the hotend? I built the unit with the fan label pointing towards the hotend as the instructions said (cannot see label after assembly) and the air flow is sucking air over the hotend, not blowing onto the hotend.
Thanks for any knowledge.

Re: Hotend fan flow direction?
technically it should be intake left exhaust right (over the probe). as with most fans the airflow goes towards the label side.
I have heard of people reversing it to keep the probe cooler but as far as cooling the heatsink it shouldn't make too much difference.

Curtis,
Thanks for the reply! I will leave per the instructions and see how it performs.
