The good
Well the other day i finally got around to installing some 40 mm fans (24v) to the x and y axis on my Sx3. I mounted them right to the shields. On the mesh end. 2 to each motor. What a difference. The motors run a lot cooler. You can now touch the motors even after it's been running for an hour or two.
Running it off a 24v power supply that I switch on before turning on the Sx3.

The warning
This don't have anything to do with the fans. But didn't feel like making two threads.

For you guys running flood systems and enclosures.
The lcd screen could be fried easily. If you notice your lcd go all wacky. Shut down. The lcd is getting wet. The plastic screen protector is not sealed. I had this happen today. I took it apart wiped the board dry and silicone the plastic plate in. All is fine now. But not sure how much of that the lcd board could handle.
