So I built a new m-itx gaming-ish machine, turns out I got a pretty bad 4670K which only OCs to 4.3GHz stably. So I tuned it and found it to work at 1.275V for 4.3GHz (could be lower, but haven't tried), for all of the tuning I used AIDA64 which pushes my H80i to around 1600-1700rpm on both fans and CPU at 75-77*C. I used it for a week and there were no errors occurring, then I tried IntelBurn test on maximum stress. To my surprise it managed to push the temps to 100+*C causing CPU throttling and BSOD once when it reached TJmax. So my question is, is 100*C normal for an H80i on a 4670K @ 4.3GHz @ 1.275V? I'm using an Asrock Z87E ITX Mobo and a CoolerMaster Elite 130 Case with the H80i pulling air on from the front. So It can't have been starved of cool air, plus my room is at around 24*C. Did I get a Dud H80i or is this normal?

Make sure it is installed correctly, it took me a couple tries to get it in right. The backplate only goes on one way and if you attach it incorrectly the block won't make proper contact with the CPU. Double check it just to make sure. I also used my own thermal paste instead of the pre applied paste. Mine works perfectly now, but my first couple tests with it didn't go well.

I have an i7 3770k @ 4.4 Ghz with max voltage of 1.29v. After 5 mins of Prime95 on all 8 cores %100 and 12 GB of mem stressed, I top out at 80C on the CPU, and the coolant temp gets to 38C. I replaced the stock fans that came with the H80i with 2 quiet, high static pressure Noctua fans that don't go over 1250 RPM at max. So if your CPU @ max is getting up to 100C I can see the coolant getting up to 40C yes, and it is totally possible that you did install it correctly, but when the H80i doesn't perform correctly that is the first thing I would check :-/ the instructions that came with it aren't exceedingly clear lol. I know it isn't a simple job, it was actually kind of a pain to do by yourself lol, but if you make sure it's installed right, then we can rule that out as a possibility. Even on the worst chips, in my opinion, 4.3 @ 1.275v shouldn't be giving you temps that high. With the Haswells you may see in the mid 80s with that on a subpar chip, which would be fine, because everyday usage will never stress your CPU as much as a stress test.
Try reseating the block, and check the backplate to make sure it is turned the right way (that was my problem, I didn't get the screws aligned with the grooves) if that doesn't work you may have a bad pump? I really don't know, but if it doesn't work when you are sure it is installed properly, Corsair deserves a phone call, or you should think about returning it where you bought it, because those temps are definitely not normal.

Ok, so I reinstalled the cooler and tried Prime95 maximum fft and the temps topped out at around 83*C although testing with IntelBurnTest still produces 100*C. So, is this ok? And is the 100*C I was getting only because of IntelBurnTest on max?

There are other factors that can affect the CPU's load temperature besides your cooler, those being, exactly how you're either Auto or BIOS overclocking to reach the 4.3ghz, as sometimes voltages left on auto spike extremely high with some motherboards to remain operating system stable, with ASRock being a member of that club.
Also overclocking you CPUs memory controller past 1600mhz adds heat to the CPU load temperature as well, the higher you push the multiplier the worse it gets, so your H80i cooler could be doing all it can, in comparison to the overclock settings and the rest of what it's being expected to cool.
How did you arrive at your overclock? and what memory speed are you running?

I didn't use any auto presets and arrived at the overclock by myself. I put 43x multiplier then upped the voltage to 1.275v then enable PLL overvoltage then I put the cach ratio to 39 and I put the cache ratio at 1.190v. I run the Corsair Vengeance Pro modules at their specified 1600mhz clock rates with xmp profile enabled.

That seems OK. (I'm sure you already know now)
The H80i is not the best cooler you could have chosen it only sports a 120 radiator and a 120 radiator by itself can only dissipate so much applied heat from the CPU.
When you reseated it, did the thermal contact footprint look like it fully covered the CPU heat spreader?
What thermal compound are you using?
Well the H80i is the baddest cooler you can get for a mini itx case since it has a pretty thick 35mm rad, except ofcourse custom WC with ridiculous 45mm thick rads and stuff. I don't really think an H80i can let a 4670K@4.3GHz on 1.275v get to 100*C, although I did use the maximum stress test on IntelBurnTest. The thermal paste seems well spread on the cpu and cooler, I'm using the preapied thermal paste. Is there anyone with a simillar setup? I suspect it's just cause of IntelBurnTest, cause if I run prime95,aida64 or just use it normally it never goes above 85*C.
So are you still on the pre-applied thermal paste? Even after removing/reinstalling the pump/waterblock?
You should thoroughly clean the CPU and the cooler whenever the 2 are separated for any reason, and apply fresh thermal paste.

First off your CPU is not bad at all. Your 4.3 ghz limit is solely due to your motherboard. But as a point of reference, I wouldn't go much more than 4.3-4.5 anyway on an H80i. I have the same cooler and I found my comfort zone to be at the 4.5 ghz range on it without getting too warm. Granted I'm running a 3570k compared to your Haswell, and Ivy's tend to run a bit hotter anyway historically, however as some have already mentioned, check your seating on your waterblock. Also re-apply different paste to it. I fully recommend Gelid GC Extreme as per an article on Tom's pastes. It was the best rated a few months ago and I knocked off 10 degrees C just by re-pasting alone. Also if you believe your H80 to be properly installed it could very well be a faulty pump. I had mine go out, but Corsair is one of the best companies I've ever had the pleasure of working with. If it is in fact faulty they will replace you with a new one no questions asked. Their warranties are second to none honestly and their customer service is top notch. Just some things to think about.

If you remove your cooler, you really need to change your thermal paste, thoroughly cleaning both the CPU and the block before reapplying. It won't be transferring heat correctly if your don't...

Absolutely correct Y0GI, That's why I asked about the thermal footprint if he didn't change out the pre-applied compound he has a worse problem now than he did before removing the thermally seated water pump block, it will have gaps and trapped air under the water block now.
@OWEN10578
Thermal compound application can mean everything in relation to overclocked cooling performance you are overclocking a hot CPU already, the temperatures should not even surprise you relating to what everyone else is getting.
Thermal compound pre-applied is thermally set and is not reusable, it should be completely cleaned off and fresh applied, you want the thinnest even coverage of thermal compound you can get, the pre-applied leaves a solid layer and is more about protecting the company that makes the cooler than your cooling performance.
Understand this Please!, You could actually run the cooler with no thermal compound the cooler does the work, but with zero thermal compound there would be air gaps and air is an insulator of the heat not a conductor of the heat.
The purpose of thermal compound is to take the place of the air and become a thermal conductor between the 2 contacting metal surfaces, and only use enough to fill the microscopic imperfections, Not a solid layer of it!
That's why inspecting the thermal footprint is important so you can see whats going on under the water pump block.
Too much thermal compound acts as an insulator instead of a conductor and cooling performance is lost.

It may be as you say, the best option for a Mini ITX, but Corsair doesn't give any claims it can take your Haswell to where you have it clocked.

I read around the web and found that the pre applied compund has no cure time so I thought that means it's ok to remove the cooler and put it back right? And the thermal spread seems ok to me. Oh well, I guess the Haswell is just hot! i guess I'm ok with it since prime95 never pushes it past 85 and normal everyday task like gaming and such only max out at 65 or so. The only time it reaches 95-100 is when running IntelBurnTest. Maybe I'll replace the thermal paste when I have time.

That's exactly right as the pre-applied is a thermal melt product applied as an even layer on the heat sink base and will not re-spread properly when removed and the initial heat bond broken, there will be air gaps left behind and that's bad!
Guys, I have a problem. I got a Noctua NT-H1 and cleaned off the base of the cooler and the cpu heatspreader, then I put a small blob in the middle. Then I boot into windows in stock speeds, and ran IntelBurnTest. Well...the temps were still 90 or so degress. Is this the cooler that has something wrong? But Corsair Link says the pump is at maximum 2200RPM. Dahell? Oh and my SP120s were blaring at 2500-2600RPM.

OWEN10578 :
Should I return the H80i to the store? And get a replacement? What's the problem here? I'm confused. I installed it right, new paste, remount tightly, run at stock, still hot.
I may have already said this and if so, My Bad.
The only purpose of thermal compound is to replace the air gap between the 2 contacting metal surfaces in so doing it conducts the heat transfer from the CPU heat spreader to the base of the cooler whatever the cooler may be air or water block.
Too much thermal compound can act as an insulator between the two metal surfaces so you want the thinnest layer of full coverage of thermal compound you can possibly achieve.
Now if that's what you have done then yes consider returning or RMAing the H80i, just be sure you've applied the thinnest amount of thermal compound you can get away with.
You do not want a thick layer of thermal compound, that's bad!
Thermal compound has zero cooling capabilities of itself, it is only a conductor of the heat, and the less you can possibly use the better.

Yes, I did use the thinnest layer of thermal compound I can. I did it twice to check the results of my application, and the first one shows the paste cover the middle part of the CPU thinly and the outside of the CPU have no or little thermal compound like what techpowerup did with the Noctua NT-H1. Also the first and second application was within margin of error in temperatures (1-2*C). I will ask for a replacement from the store I bought it from and if they won't replace it I'll RMA to Corsair.
Thanks for replying!

There could be something wrong with the pump, or partial radiator blockage affecting the coolant flow, etc., they're produced on a mass scale so you could have easily gotten a bad one.
