There are lots of Haswells running at stock speeds with stock OEM air cooling that run up to 80*C.

It's all relative. Is 70* safer than 80*? - yes.

Is 80* safe? that depends on many factors.

Hmm, see this is what I'm finding all over the place. There is always some disagreement about what is "safe" with the Haswells.

Well just to close this thread off I ran it for a couple months at those temps, OC'd to 4.2 with the stock cooler and never had any issues really.
Maybe I slightly reduced the life of the chip in some people's opinions but I went out and got a Hyper 212 EVO now so I'm idle at 37 and full load at 64, so def better. I could add another fan to the EVO and do push/pull or maybe go water in the future if I want to OC more.
I am going to try 4.4ghz sometime soon with the EVO and see how my temps are so I'll come back and post the results if I do get around to that.

Thanks all.

Intel know exactly what the tolerance of the Haswell architecture is, so if the stock cooler puts you at 90c, then they must have assumed its safe enough to do that at stock clocks and volts.
When you start adding voltage and then start hitting these same temperatures, more damage can be done quicker. So ideally we would want to keep the chip as cool as possible when overclocking. There is no safe limit, but just know that the higher temps you run, the quicker the degradation may occur with higher VCores. Id not run the chip passed 80c whilst overclocked, this is more of a comfort zone, no one can give a definitive answer.

I personally prefer to keep them under 80c full load.
