Hello,

Just got my H80i installed and have started to tune my rig.

Before I got my H80i, I just tested a bit with my stock cooler.
With my stock cooler, I got a stable 4.3GHz @ 1,250v but with to high temperatures. Reached 100 degrees running AIDA64 and the cpu throttled down.

What I can't understand now is that after I installed the H80i, I can't even run the cpu at 4.0GHz @ 1,250v without windows freezing, while running AIDA64. The temperature is never over 70 degrees before it freezes.

Why is this? Can the CPU be more unstable just because I changed the cooler? I'm getting lower temps after I installed the H80i, so I'm guessing that there is good contact between the cooler and CPU.

Any thoughts?

I ran AIDA64 for about 4+ hours with no problem. If I don't consider that the temp had peaked to 100 a few times and the CPU throttled down.

If I now run AIDA64 at 4.3 or 4.0 @ 1.250v the computer freezes after 5-10 minutes.

Don't run 4.0 at such high vcore. Some chips/boards cant handle overvolting well and need some tweaking to get stable oc.
Try to run 4.0 at 1.1 vcore. If it stable, raise to 4.1 without changing vcore unless you start getting 101 bsod's.

Here is the thing. Your problem stems from cooling issues. Your stock fan was blowing air over your other heatsinks around the motherboard, now that it is absent, nothing is cooling or taking away the heat. Is there anyway you can remount your H80i to also blow over your motherboard's heatsinks?

But I find that really weird since its not like you are doing 5Ghz+ for your system to act as though other parts are overheating, check your bios for settings that are not right... doesn't make sense why your system is responding as though some parts of it are over-heating. How is your air flow?

I can give that a shot. Just think it is weird' that it ran ok on 4.3 @ 1,250v on stock, but not on H80i

Yes, the H80i in push-pull setup is taking a lot of space over the motherboard. But the motherbord temp is only 24 degrees, but maybe some of the heatsink that is "under" the H80i is getting to hot?
I have 2 fans in front that is blowing fresh air into the case, and the push-pull H80 i that is blowing out of the case. Have also a top-mounted fan that start to blow air out from the case when the motherboard get hot(this one is not blowing all the time since I want to try to keep a overpressure inside, since there is a dust filter on the to fans in front).

Have tried it before, but will reset the BIOS to default and start over, yet again.

Every time I have tried overclocking(stock & H80i), I have followed this guide: http://www.youtube.com/watch?v=1DqIG_89Mcs
And as mentioned, on the stock cooler it went great, if you disregard the temps

Wait, are you saying you ran AIDA for over 4 hours with your temps hovering around 100c?

No, when I returned to the computer I saw that it had peaked to 100. Average cpu temps was 70-80.

I thought this was a third gen chip until I looked at your setup in the signature. Have you tried other stress testing apps like LinX or prime to verify that the problem you are experiencing isn't software related?

Seems weird that your OC is unstable if the only change you made was to get a better cooler and temps are even lower than before. I would recheck the cold plate contact as well as making sure you don't apply too much pressure on the cpu when you're screwing in the cooler.

No, have only tried AIDA64, since that was the one recommended in this guide http://youtu.be/1DqIG_89Mcs?t=26m55s
They said that we should really not use Prime with haswell..

Could the pressure cause this effect? May be that I put on to much pressure. Will try to release some of the pressure.
But is away on a trip now, so not able to check it out before tuesday at the earliest.

How do you check the CPU temperature? The Corsair Link utility used to configure the H80i by default shows the Coolant (liquid) temperature. If you are checking this then there is a possibility that the cooler is not properly mounted on the CPU. You can verify this by checking the actual CPU temperature (available within Corsair Link as a separate configurable monitoring parameter or another utility like Speccy or RealTemp). If you see a large difference in temperatures of the coolant and the CPU then it means that you may either need to tighten the cooler block or remove the cooling block and remount with new thermal grease.

I'm not sure if you are aware of this (I was not, when I first used my H80i), but by default Corsair Link uses the coolant temperature to vary its radiator fan speed. You can change that to make it so that the radiator fan speed varies based on the CPU temperature, which I think makes more sense.

Hope this helps and all the best!

I tuned down the voltage to 1,175V @ 4.0GHz, and now AIDA64 has been running for 50min and still going strong. So maybe there is something to what you said!

That is 40 minutes more than on the higher voltage.

Have noticed that the Corsair Link is running the fans according to the coolant temperature. Have not figured out how to change that yet.
And off course I'm using RealTemp and CoreTemp to monitor the temperatures.
