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?

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.

As per my above, I can give some details:
At ambient room temperature of 24degC (air conditioning) your CPU is likely to be in the 60's degC under full load.

Make sure you just choose "XMP" in the BIOS, then save those settings. Then, test with MEMTEST (DDR3 memory) and the Intel diagnostic utility, and Prime95 if you want for the CPU.

I believe "XMP" on the right motherboard is told to choose 4.4GHz for Turbo mode by default so the Intel Power Management should be intact. If it wasn't and you manually go above this the temperature jumps up quickly.

I'm saying this because others may say 70's or even 80's for temperature but this new CPU was redesigned to lessen the local overheating issue and I believe the XMP profile defaults to 4.4GHz. So again, this is all keeping things optimized for power management to keep it cool.
 


Unless he wants to really push the limit in which case temperature really rises quickly, the Noctua NH-U12S is a great cooler for the i7-4790K at 4.4GHz (with again should be with power management intact). My estimate is that it should be in the 60's at 100% load depending on ambient room temperature, case cooling etc.

The max temperature is probably around 100degC so really we're just concentrating on the NOISE aspect at this point.

The Noctua NH-U14S would be slightly quieter under maximum load but going beyond these coolers is generally pointless.

Thanks. If im honest, i'd rather get H100 or H100i which one is better? H100 probably cus of 2x 140mm? And btw, my case is Thermaltake mk-1. Will it fit ok?

Well guys, at first i just want to say, im really appreciate your help. I just dont know, wich answer should i pick as solution. Who needs ''solutions'' ?
I think i'll go with h110. Currently i have H60 and im really happy with Corsair H coolers, so i'll stay with them. Once again thank you guys. Blackbird nice profile.
