I went ahead and went with the i7-3930k should be here by wednesday or friday, but I had a quick question on additional cooling, right now I will be recieving the gaia 30$ cooler with 2011 bracket so thats fine and dandy(will only clock to ~4k), but I want to push the OC to about 4.4 or 4.5 safely so these are my two options im considering unless you have a better idea.

Noctua NH-DH14 SE2011
http://www.noctua.at/main.php?show=productview&products... (Newegg doesn't have it available yet, but I was able to find it on Amazon and a couple other sites for 85-95$, most places haven't recieved thier stock yet just released this month)

or

CORSAIR H80 (CWCH80) High Performance Liquid CPU Cooler
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

No rush on ordering, but ideas and advice would be appreciated. Will be ordering new heatsink or liquid cooling before Christmas time this year.

Best solution

If you have the room then the Noctua, otherwise go with the H80.

For some follow-up, I received all my parts this monday: i7-3930k, p9x79 pro, 16gigs mushkin quad channel 1600, hd 6970 and I'm using a xigmatek gaia heatsink and fan at the moment, my comp is idling between 30-38C, and goes up to 70 on a full load running prime 95, Its only OC'd to 3.9, only changed the multiplier to 39 but these are the temps its running at, 50C while gaming as well.


Seems a little high, but according to this chart the 3930k does idle at 35C when OC'd to a much higher frequency.

I am concerned that maybe I didn't apply enough thermal paste or the contacts with the heatsink isn't fitted perfectly but don't want to make an adjustment until I receive the NH-DH14 SE2011 in about 2-3 weeks.

Will I be able to bring the temps down to about 30C while idling with the Noctua at 4.5ghz? and What is the best combination for bus + multiplier for frequency when clocking a 3930k to 4.5? Do I need to adjust the voltage?

Sorry lots of questions, first system I've overclocked.

You should be able to get something around low to mid 30s C with the Noctua at idle. As for OC'ing most mobo OEMs provide OC options in the UEIF. Those options use proven bus, muiltiplier and voltage settings, and you don't need to fiddle with them. My mobo allows me to OC to 4.8 GHz stably. For a first time OC'er I recommend that you try out the UEFI OC settings.

Remember that the LGA 2011 chips run significantly hotter than any LGA 1155 chips due to the extra two cores and higher TDP. What matters the most in terms of heat is the core voltage, what is that set to?

@Chesteraco... I do have a UEFI Bios, I'm using a p9x79 pro from asus and that is where I changed the multiplier from 33 to 39 for the 3.9 OC. I'm trying to ask for 4.5ghz should I increase the BLCK Freq to 125 and multiply by 35 or just BLCK 100 and use a multiplier of 45?

@gmcizzle The VCORE is at 1.34. Is this good or bad? Should it increase for a 4.5ghz OC? Also if you have input on the previous question that would be appreciated!

Sorry for late response, just got off work.

The amount of vcore you need depends on the individual chip so you just have to play around with it. I'm not familiar enough with the 3930k to know if those temps are good for 1.34v or not. The xigmatek gaia isn't quite as good as a NH-D14 but it's not far off. You may want to look into getting a Corsair H100, if your case can fit it, if you want much better temps.

Is the Corsair H100 loud? On another tech forum I was informed that liquid cooling tends to be quite a bit louder than the Noctua. But I do have an NZXT Phantom case, very large with rubber grommits in place for liquid cooling! Right now my computer is incredibly quiet and I had a noisy machine previously so I'd like to stay more on the silent side of the spectrum.

Yeah it's louder than the Noctua slightly. I'm not sure loud it would be mounted in the Phantom though but yes it would be louder than the Noctua on max fan speeds.

Is BLCK at 100 with multiplier of 45 more optimal than BLCK of 125 with a multiplier of 35?
