I got a surprising overclock (4.7) on my 4670K - Page 3

post #21 of 23
Auto voltage tends to apply more voltage than necessary, which is bad for your OC. In extreme cases, high voltage settings with auto settings can kill CPUs... I would back off as soon as possible.

I have no personal experience with haswell, but I can tell you over 70C in any CPU is considered bad, over 80C at high voltages with haswell is dangerous, anything over 90C means your CPU is slowing itself down to stay alive.

You should start at something conservative, say 4.0ghz and close to stock voltage set manually. Then gradually bump up the clockspeed until you start crashing, bump up the voltage a bit, and repeat till you hit 65C at load.

over 70 on an Intel processor isn't bad at all, mid 80s during stress tests(prime,ibt,etc) is about as high as I personally go before lowering volts/clocks but 70 is more than fine

Over 70c is fine, intel cpus dont throttle until over 100c.

Staying under 80c is good for longevity, but not definitively necessary.
