CPU temps at 7GHz

[AFellowGamer]

I know that the Haswell CPU has overclocked to 7GHz using liquid nitrogen. This is just out of curiousity but can anyone give me an estimate of the temperature of a 7GHz clocked CPU with no cooler?

if it would be possible, ( which is not since the CPU would shut itself down about 90-100c and fry at 100-120 ) but it would be around 200-300c?
