The new gen intel processors reach 105C without a problem.
That's not true. If you go above 80 every day, don't expect it to work for more than 2 or 3 years.
Ivy Bridge gets so hot because they used bad TIM between the heatspreaders and the cores themselfs. That's why I chose Sandy Bridge instead of Ivy Bridge, so that I wouldn't have to take risks by removing the heatspreader.
