Is the shutter (a manual slide in front of the lens) open?
As for ultra performance, you can have that and noise, or slower performance and more tolerable noise. You can't have both quiet and ultra performance -- the system doesn't have the cooling capacity for that.

Please see this article for the camera and mic 0xa00f4244 errors. A 5450 may have a MIPI camera so this article may also apply. As to the fan noise, is it grinding, buzzing, clicking, or high pitched? That may be a bad fan bearing in particular. If its just a high fan speed, then that may be a limitation of the ultra performance setting. You can also run a preboot diagnostic to make sure the fan is passing its test.
