Noise - because your fan is working overtime trying to cool the cpu

Shutdown - the cpu got too hot, so the computer turned off, hopefully to avoid any serious damage

It's overheating MOST LIKELY due to excess dust build up around the fan / heat sink radiator area. This is preventing the fan from dissipating the heat from the heatsink
