Although I think it's unnecessary as the stock cooler is pretty quiet and cools well up to 4.5GHz, If you can find a decent tower style heat pipe cooler for under 20 bucks shipped it wouldn't be the worst way to spend your money.

You have to take into consideration that these G3258 chips pretty much hit a brick wall after 1.3-1.35 volts meaning to get the last 100mhz of speed out of them you need to really turn up the voltage.

I'm using the stock cooler on mine. Ran all night at 4.5GHz/1.275V. Temperature fluctuates wildly between 72C and 84C, but on average it was about 79C. The load was 100% on the IA cores plus a HTML5 fishbowl to drive the GPU to 10W TDP.

Ambient was low however, at around 18C. And my board is not in a case yet. We have that polar vortex thing going on right now, so although its the middle of july, its not a very good time to test worst case ambient overclocking stability.

4.9ghz is good on any air cooler. That voltage is not what I'd want for a daily overclock, though . . .

No, it was just to see what it would do. Interestingly, temps were no issue at all, I think I bumped 85 a couple times max during Linpack at that speed/voltage. Definitely turned it back down as soon as testing was complete, I would not call that a 24/7 setting, though it did seem pretty darn stable.

Interesting. That seems to indicate that superior cooling wouldn't have helped you very much to gain stability at the same speed with less voltage. Maybe if you had been able to drop 30C or more, you could have pushed less vcore, but maybe not.

Something that may be slightly topical is that I had to use a beta BIOS on my Z87X-UD4H to enable overclocking on the G3258, and the beta included a new interface which I have seen on newer Gigabyte boards. I'll need to re-test my 4770K to be sure, but the way it now handles voltages makes me think the changes between Z87 and Z97 noted here might have more to do with firmware rather than hardware, but that's just a guess right now.

Huh . . . that is interesting. I'm sure you're well-pleased by this behavior from your Z87 board nevertheless.

The stock cooler is actually pretty quiet.

In fact, when I play Battlefield 3 64 player at 4.6 Ghz (1.3 volts) using the stock cooler I notice my temps (measured by Speed fan 4.49) barely go over 60 degrees Celcius. (About 10 degrees lower than my Prime 95 stability test temps)

Hi, I recently build a system with a b85g43 gaming MSI and a g3258 I can't pass 4.4 GHz I'm at @1.28 vcore and got 80's at intel stress test and mid 60's on battlefield 3 if I go to 4.5 it always crashes even @ 1.3 I'm using stock cooler can some one help me I don't if I have to increase another value in order to get my sysystem stable at 4.5 thanks
Edit I applied article cooling mx2 thermal paste I applied it directly on the new stock cooler I don't know why I'm getting that high temperatures.

4.4 Ghz is a good overclock.

Not all G3258s overclock the same.

P.S. Regarding my reported temps, realize they were on an open bench and later I noticed Hwinfo64 and MSI afterburner were reporting about ~10 degrees higher than Speedfan 4.49.

Not sure on that chip, but a NH-D14 gets me to 4.5 on a X5680 on air.

Thanks for the quick reply I'm planing on buy a evo 212 and see if I can't get 4.5 or 4.6 in a better case.
