A brim will help but the biggest thing is not to use fans at all during the first several layers and very sparingly after that. Also be sure your printer isn’t getting hit by a draft from an air vent or open window. PETG warps badly like this from too much cooling/temperature variation.
Try with maybe 20-30% speeds after its printed several layers at 0%. You might even try your idea of zero fan the entire time. It’ll take trial and error so you may figure out a way to test on a smaller print so you don’t waste a bunch of filament.
I’m starting out with 0% first. However, I wonder if it will break my hardware as a device melting plastic at 245 C should have some cooling system or it will burn up right?

How much % is sparingly? I’m thinking of turning them off the entire print. It’s a pretty large print
