<p>I am building an enclosure for an Ender 3 Pro printer, and am planning on the power supply and LCD unit being outside the enclosure.  How important is it to move the printer controller (where the SD card is inserted) outside the enclosure?

What will the temp inside the enclosure be? Is that safe for your board? Will opening the enclosure to load the SD card release your warm air?

It's not just a question of lifetime of the board, but whether the high temps might cause failed prints due to stepper drivers shutting down from overheating or other similar issues.

Also depends on the drivers used - how much heat the drivers will add. Still using the stock board?

It depends on what kinds of prints you make, and especially what kind of materials you want to use.

Certain materials (ABS especially, but also PETG to some degree) will print *much better* if the entire build area, which usually includes the printer chassis and controls, is enclosed to protect from drafts and allow a much higher ambient temperature.

If you print often with these materials, and the control board is included in that enclosed area, you ***will*** significantly reduce the life of the electronic components, [especially the capacitors on the board](https://en.wikipedia.org/wiki/Capacitor_plague)1.

On the other hand, if you print mainly with PLA, which is not as susceptible to issues requiring an enclosure, and prints better with an ambient temperature closer to room temperature, you can put the electronic controls wherever you want.
