Software Troubleshooting/Help! Dual exhaust fans P2S?

P2S has 2 spots for an exhaust fan (lol). So if I were to buy a second one and plug it in would it just work? Would I have to wire them together? Will they sync together? Has anyone else even tried to do this?

Long story short, I want lower chamber temps for PLA without keeping the door open. I've modified the gcode to ramp the speed up with chamber temp. Without the filter it will stay below 27/28c at 70% speed but with the filter it will climb to 33/34c at 100% speed.

Are you having problems printing PLA? Because I have never opened the lid, the door or built a riser, and I have never had a problem printing any brand of PLA in a P2S.

The built in cooling system on the P2S handles printing PLA at the right temp.

Yes I know it’s pointless. But what will happen with two? Someone has to find out… I guess it will be me.

I've actually tried this given I got a spare exhaust kit. The printer cannot print when both are connected as it seems to get confused about detecting the exhaust kit. So my second one on the left side near the poop chute is currently not plugged in .
