Hello guys. Im getting a new cpu and mobo. Upgrading from i7 2600 and maximus iv gene-z TO i7 4790k and rog maximus vii hero.
Im wondering what cooler should i get? I'll push it to at least 4.4 ghz. I need your help, overclockers.
Btw im selling old cpu. How much is it worth? 200€ for CPU and MOBO? or is it too much?
 
Solution


Noctua NH-U12S. or NH-U14S.
I've tested the NH-U12S, the NH-D14, and the CM "EVO" cooler on an i7-3770K and i5-4670K (at 4.2GHz).

I've found the NH-U12S to be dead silent in idle and not very loud using Handbrake at 100% usage of the i5-4670K. The i7-4790K uses Hyperthreading but it's also been redesigned to run cooler so it should be similar the i5-4670K for cooling.

Make sure you have your Fan Control software setup for the motherboard. The Noctua NH-U12S should idle about 300RPM (couldn't hear from six inches away) whereas the "EVO" from CM was audible even in idle from several feet.


If you use the "XMP" setting then your CPU should default to 4.4GHz or 4.5GHz. Someone told me 4.5GHz for his Asus board.

*So you really shouldn't go above this, especially since doing so removes a lot of the Intel Power Management so you get a huge jump in the temperature and need more cooling. The real-world benefit for processing is essentially zero for gaming and maybe 4% or so for converting video.

So if using the "XMP" setting the Noctua NH-U12S is quite sufficient to cool and will be far quieter in idle and probably quieter even under full load of the CPU than the H100 liquid cooler.

(Liquid cooling also reduces air flow over the CPU voltage regulators which normally have a CPU fan next to them, and done properly should have the fans as INTAKE thus changing your air flow design for the case. Add this to Pump noise and you need a good reason to justify a liquid cooler which I can't find.)

So again, my strong recommendations for CPU cooling is:

1) Use the "XMP" setting in the BIOS

2) Use the Noctua NH-U12S

3) Setup fan control software (run quiet in idle, and ramp up above 40degC or so)
 


Well, didnt expect such a usefull answer tho. Im really looking for Noctua now. Its a bit cheaper, but hydro is most nice-looking cooler. But what about Noctua NH-D14 or D15 ? Or shall i get my hands on your top suggested U12S ? Im ready to pay extra 20€ if there is any difference betwheen NH-Dxx and U12S.
 
The Noctua NH-U12S brings about the same temps(maybe one or degrees higher) as the NH-D14, but it is much smaller.
I would get the NH-U12S if I were you, the system I'm building will have it in it.
