I5 2500k @ 4.5ghz 1.352v safe 24/7?

Hey I just overclocked my 2500k to 4.5ghz with 1.352v.
Was wondering If it'll be safe for running 24/7?

full specs:
Case: CM Storm Trooper.
Mobo: Asus P8Z68-V LX
CPU: i5 2500k
RAM: Cors Vengeance 1600Mhz 2x4Gb
Cooling: Corsair H80
GPU: MSI r6970 Lightning
Power: Corsair - Enthusiast TX750M

I live in a cold enough country so my ambient temps are around 15-20*c

Running prime I maxed out at 71*c on core 1 and 68/67 on the other 3 but after that maxing out it sat at 68 the whole time. Is there any chance of this damaging the cpu or are these temps safe?

The temps that you are getting are ok, what about the idle temps? Normally a cpu could withstand 95ºC top, but that's the limit, so no use on getting near there right?
Again, how are you doing with your idle temps? are you manually setting the volts or they're on auto?

1.24? thats so low gonna have to do some tests. what are you temps like? and what cooler?

Remember that core temps measured on die. When peeps talk about max cpu temps they mean temp under heatspreader, which is 8-10 C lower. Also max temp for ur cpu is 72. Ur voltage is kinda high, but it all depends on cpu batch. I'm hitting 4.7 @ 1.325

ok 1.27 instantly crashed as soon as i started

It gets onto windows. its prime95 that insta crashes it. My bios is being retarded. its showing a different voltage all the time each time i go into the tweaker tool -.- and it dosnt let me set a voltage either, theres only some voltage I cant change(which constantly changes each time i load up bios) and theres an offset.. I set the offset to 0.100 and when the bios is at 1.207 apparantly now on cpuz it shows 1.360 while running at load. this crap his unreliable -.- I shoulda left it at 1.352 because that was stable and didnt cause probs. now I've to get rid of this high voltage xD
Is it ok for it to be jumping between 1.352 and 1.36?

Make sure it can pass 6 to 8 hours of Prime 95 to be sure it's stable.

either I think
