Hi as the title suggests, I have done my first overclock ever... I managed to get my i5 3570k to get my cpu to 4.5ghz at 1.32v.

The temperatures at idle are 23-29 degrees.

The temperatures at maximum load are hitting 70-77 degrees after a hour and a bit of testing on prime 95 torture test... (it's still running).

Are these temperatures safe?

Also my voltage is at 1.3 to 1.32v.....is that safe for a 4.5ghz overclock for 24/7 use, if after 5 hours or so of testing it seems to be stable?

or is it too damn high for 24/7 use ahaha :) 

any comments or thoughts will be much appreciated


I'm using hyper 212 evo with mx-4 thermal paste
I'm using 7 fans on a zalman z11 not including psu or heat sink one obviously.
2x8GB of RAM
a 1200w gold certified PSU
nvidia gtx 660 twin frozr oc edition
msi z77 gd65


Also is it worth adding in an extra 120mm fan to the hyper 212 evo to lower the temps?

Best solution

The voltage and these temperatures perfectly safe both load and idle.
Normaly the lower it is the better. No woories. your fine. 4.5GHz is a good 24/7 overclock. Mine does only 4.4GHz 24/7
Adding another 120mm to the hyper is greate idea push and pull will give 2-4c less temp on load.
Thanks

Thanks a lot dude you made me much more comfortable ahaha :)  and yup I'll do the push/pull thing thanks again :D !

Let me ask you what are you planing on doing that you need 4.5Ghz 24/7?

Goldfarming on a large number accounts for extensive periods of time..
Gaming (I know that's not cpu extensive)
Coding
and livestreaming :) 

so is that a good idea or no? any feedback would be good thanks :)

Push/Pull gives little to know advantage, mount the fans on the case then the radiator over then so u can easy clean the radiator, just use pressure optimized fans like Corsairs SP120/140mm or Noctuas Static Pressure fans. Push/Pull is just going to create more noise.

Also try just increasing the turbo clock, that way u still get the speed for gaming but the lower clock speeds and lower temps on idle. I have the 3570K and it will run around 1.5GHz surfing the web and at 25 degrees Celsius. When im playing a game i can achieve a clock speed of 5.0Ghz with Intel Turbo Tech.

No don't do that, that's a bad idea. Who wants their CPU throttling up and down and up and down 24/7. Not only that, but it's harder to get a stable overclock when your constantly having your speed changing.

It's also better to not enable turbo boost as it makes your CPU unstable when it's trying to push that one core up to 5.0Ghz. I've been told numerous times it's not worth it. It sounds all good, sure, but that's not always the case. The best and most stable overclock is one with a fixed voltage and fixed multiplier. Most people who overclock can tell you that. I can tell you that anyone that professionally overclocks does it this way.

Well tell me this, I just built a new computer and I can't get the BIOS updated so I can't get my CPU over a multiple of 43 on my reference or boost, it doesn't get hot so I'm assuming that its a problem with the BIOS. Do you concur.

I'm not too sure. I would assume that it's the BIOS though. That's what I would check first.

i dunno, id much rather keep temps down with speedstep and when gaming get my 4.5ghz.

how would you even do a constant 4.5? just turn off turbo and use multiplier like before?

I'm using hyper 212 evo with mx-4 thermal paste
I'm using 7 fans on a zalman z11 not including psu or heat sink one obviously.
2x8GB of RAM
a 1200w gold certified PSU
nvidia gtx 660 twin frozr oc edition
msi z77 gd65

What are you using to check temperatures? If you are only hitting 70°s at 1.32V I am a little suprised. You should be running Coretemp or similar.

I'm guessing you are not doing Small FFT torture test on P95? Small FFTs will push CPU the hardest... but keep an eye on those temps. Honestly your voltage seems a little high, but if your temps are legitimately that low you are probably fine, as long as you turned all the voltage controls to manual settings (where the CPU is not spiking up past that).

Next thing to do is go to event logger in windows, and see if you are getting WHEA errors. I was pushing my 3570k as high as 4.5ghz, but I backed it off to 4.3ghz with more comfortable temperatures and voltages to get a stable overclock with no WHEA errors.

The "invisible wall" on my chip was lower than others I have read about, but the overclock is rock solid and im sure it will last me for years to come. Overall im happy with the upgrade from a Q6600.
