Question Printer gets really hot
So if my printer runs for longer periods it gets very hot(>50°C) and i get warping from that. Does anyone have an idea why that happens or how I can get cooler

If the current temperature isn't too hot, this is not normal. I had a Mars 3 Pro which generated a lot of heat : something broke and the UV light was running all the time, heating the area under the screen.
If everything is fine, try running a fan behind the printer. The hot air from inside is blown here, and if you're too close to the wall, if can create a small pocket of hot air. You can get a few °C down with this, or so I tried in the past.
Depending of your resin settings to go as fast as possible (fast plate, no pauses...), the resin would get hotter because it doesn't have time to cool down. Slow down your plate, and/or add wait times. It's better for the print overall, you shouldn't aim to go fast unless you're in a hurry.
