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?

typically the fan cooling the heatbreak and extruder stays on even with the "extruder" aka part cooler fan turned off

As the other person stated, the hotend has two fans. One for part cooling and one to cool the extruder itself. The latter is usually controlled by the printer with no way for you to change it (apart from maybe rebuilding your own firmware) so you will be good to go running at 0%. The issue with this is that some part designs need the plastic to be cooled quickly for things like bridging, which is where you’ll run into issues having the part cooling fan turned off. That probably won’t be an issue when printing a box though.
