XYZ Calibration cube

I’ve recently purchased a Creality Ender 3 3D Printer and have run a few tests with the XYZ Calibration cube. For some reason, it appears I need to set the nozzle at 240C and the bed at 70C to even get a semi-decent XYZ cube. Not sure if the printer is faulty as some people have suggested or something else is going on. I tried also printing using a profile file someone had uploaded and posted on Reddit but it didn’t help. I’ve made a video of the printer doing the XYZ cube below:
