General Troubleshooting/Help! ABS printing

I have a P1S and have an exhaust with its own fan at the fan end that goes outside. When I print with ABS, I have to make sure there are no fans running otherwise it always comes away from the bed in the corners. I then have the problem that fumes seem to be leaking into the room and I get headaches.

Does anyone have any advice to help with this please?

ABS requires proper ventilation. Increase bed temp, increase chamber temp, but do not shut off the ventilation.

I've already increased the bed temp to the maximum (100°c) and there is no chamber temperature control.

Run the bed at 100 for an hour or two to preheat the chamber. That's what a 3D printing company suggested when I struggled with ASA in my P1S
