Motherboard showing insane temps right after boot

[KingDabz]

My motherboard is reading at over 100 degrees as soon as i boot his new build, but i can touch the motherboard anywhere i please and its NOT hot to the touch, are bot programs getting bad data from the same spot? All the components for this build were bought used. 

 

Not sure if it's worth mentioning but when I put it all together and booted the fist time the PSU was switched to 230 instead of 115 and the computer shut itself off after I plugged in a USB wifi stick, windows said it was surge protection, so i flipped the switch back to 115 and it hasn't shut down on i's own since
