XDJ Seizing with pitched sound: MY PC made the Same Sound when it froze and GRaphics card was overheating

just had a brainfart, have PIONEERS technicians considered the fact that the Freezing and high pitched noise is very similar to something that

happened with my PC, my graphics card would bug out screen goes green with glitches and the same high pitched noise....... the processor in the XDJ R1, how is it kept cool..... is it not overheating especially when the unit is being used for a good couple of hours a night, won't overheating cause the same problem on the XDJ R1 as it would on a PC's processor.
