In my opinion good overclock is when your cooling can deal with heat so that temperature doesnt go over 90 under load. I dont care much about voltage but those 4,7 ghz is pretty sweet.

For overclocked CPU and H100i those are good temps. I will personally soon get H100i and 4790k too.
Kraken x61 is beeter than h100i so chck out that
My specs are
Processor - INTEL i7 4790k devils canyon(haswell refresh) @ 4.6ghz on 1.26v
Motherboard- ASUS REPUBLIC OF GAMERS MAXIMUS VII HERO
RAM- G.SKILL RIPJAWSX 2x4GB 2133mhz
Cooler- nzxt kraken x61 liquid cooler with noctua nt-h1
Graphic card- SAPPHIRE R9 280x VAPOX 3gb xfired with r9 280x black edition
PSU- COOLER MASTER silent pro M 850w
CABINET- corsair air 540 HIGH AIRFLOW (with 3x CM jetflows and 2x CORSAIR AF140)
Lighting- NZXT HUE RGB Controller
Fan controller- NZXT GRID fan controller
Harddisk- WD caviar green 500Gb
Ssd- 120gb 840 evo
I can't get anything stable higher than 4.5ghz. 4.6ghz at 1.28vcore is the closest I can get, however after leaving on the stress test for around 3-5 minutes it ends up crashing. Max load temps are at 80-85c with sunbeam contact freezer.
Guess it's gonna be 4.5ghz like my good ol' i5 2500k.

hey guys im just wondering if my overclock means i have a good chip? got it running at 4.7ghz with 1.25v is this good? should i try and overclock the northbridge or just leave it at 4ghz? thanks in advance guys 
I have similar set up to other guy 4790k corsair 105 w/cooler twin 280x 2133 16g ram asus v11 hero mb mine runs at 4,8ghz all day temps are low sisoft bench marked

I ended up stablizing my 4790k at 4.6ghz with 1.312vcore on air..
Damn liquid cooling. I'm still confused how people are stable 4.7ghz at 1.25v even when temps aren't the issue.
My temps are completely fine but it just simply crashes at that voltage level, it isn't enough.

It's all the luck of the silicone lottery. I do 4.7ghz at 1.268v but for 4.8ghz, I have to jump up to 1.35v and even then it's only stable for a few hours before I get a BSOD while testing it with prime.
I've read other people doing 5ghz under 1.3v which blows my mind that anyone could get that lucky but ultimately overclocks that high seem to be the exception not the rule. 4.6ghz is still plenty fast on that architecture so it's by no means bad. It just goes to show how inconsistently binned the 4790k is and how Intel's marketing was BS when it came to the overclocking headroom of it as well.

Yeah interesting. Not complaining at 4.6 by all means as 4.7 and 4.8 won't see much performance gain anyways. You're right about the marketing about OC headroom especially from a base clock of 4.0ghz, 5.0 would seem atleast the norm. My old i5 2500k was stable at 4.5 from a stock of 3.3 which was very nice but hey atleast I beat the 2500k's speed

I guess if you want to be pedantic, the 4790k is a factory-overclock 4770k so a 4.7ghz OC from an original 3.5ghz clock is fantastic in the grand scheme of things.

In that case it's some decent headroom.
1.30 was my goal but 4.6 simply could not handle 1.28 even with temperatures in the 50's.
I set a manual voltage level of 1.28 or 1.29 vcore to stay within max range in the mobo settings but it appears it's off a bit and auto bumped the end vcore to 1.312 under full load. Did the trick anyways it's stable now, with max 100% load temps in the mid 60's under AIDA64 cpu stresser using hyper 212 evo. Great cooler as well.
