Fan Orientation/Replacement/Upgrade

Post by brunningm » Thu Oct 19, 2017 1:05 am

Hi All,

So when I replaced my motor, my instinct on putting the fans back was to make them both 'push'. The Nozzle blows air down through the vent and cools the nozzle. The motor fan blows air into the motor.

While I'm 100% on the nozzle...I'm beginning to wonder if the motor overheating is due to the fan orientation over the motor itself. Should I instead 'pull' the warm air off the motor?

Also, has anyone had any success in changing the fans to something else? I've been thinking about the Noctua 5V fans. They're PWM so I would need to rewire for the DC output...but I don't want to put too much strain on any of the system and cause a short.
