by overclock, do you mean full-out running at peak all the time? or letting the CPU governor still work and just bumping up the limits?
one makes sense, the other is hubris.

In theory, TDP scales linearly with clockspeed. In practice, power increases higher than that rate. 30-35% increases in heat to dissipate is significant.
I'm old school when it comes to overclocking. Stability and sustainability matter to me. I don't always run all cores full-on for hours, but when I do, I want a cooling solution that's up for the job.
With an overclock, even a FLIRC would throttle when running our full unit test suite. A 30% reduction in unit test runtime is nothing to sneeze at and I certainly didn't want to downclock to 600-800MHz due to throttling. An ICE Tower was a lifesaver.
