(i put a bit too much) It seems like it made good contact, right?

Doesn't look like an even contact, see how the middle is thinner than the outside? I think your cooler block is warped (it could be the IHS but that's less likely). Seems like the block is warped and making a bad contact. Is it under warranty? You should RMA it.

Having issues with a Corsair AIO? Possible fix here:

Spoiler

Are you getting weird fan behavior, speed fluctuations, and/or other issues with Link?

Are you running AIDA64, HWinfo, CAM, or HWmonitor? (ASUS suite & other monitoring software often have the same issue.)

Corsair Link has problems with some monitoring software so you may have to change some settings to get them to work smoothly.

-For AIDA64: First make sure you have the newest update installed, then, go to Preferences>Stability and make sure the "Corsair Link sensor support" box is checked and make sure the "Asetek LC sensor support" box is UNchecked.

-For HWinfo: manually disable all monitoring of the AIO sensors/components.

-For others: Disable any monitoring of Corsair AIO sensors.

That should fix the fan issue for some Corsair AIOs (H80i GT/v2, H110i GTX/H115i, H100i GTX and others made by Asetek). The problem is bad coding in Link that fights for AIO control with other programs. You can test if this worked by setting the fan speed in Link to 100%, if it doesn't fluctuate you are set and can change the curve to whatever. If that doesn't work or you're still having other issues then you probably still have a monitoring software interfering with the AIO/Link communications, find what it is and disable it.

Im pretty sure it was stepping, because at idle the clock speed dips down, but when I AIDA running, it goes up to 4gz.:S

No worries, it was just something to try. On second thoughts I dismissed the idea anyway, but still could have been useful to reset to defaults anyway for troubleshooting purposes, so I left my comment in. If trying to troubleshoot something it's the first thing to go, even if you KNOW it couldn't be the OC causing the problems IMO. Anyway, good luck with the problem, it's looking more and more like a defective AIO cooler then.

Ummm, is it just me... or does that look like the sticker is still on the block?

No, thats just some residue from the pre-applied thermal past from the factory. I couldn't get it off-_-

Ahh I see, well it really needs to come off... the blocks/cpu should be really clean and free from any residue etc as that can greatly affect the thermal transference. Scrape it off with a soft plastic card or something as much as you can and then use iso-propyl (sp?) to get the rest off. It should come up nice and shiny.

It looks ok. Not much in the centre though. Still would expect temps to be lower then what you are experiencing. Ate you using a fan controller?

Have you tried turning it off and on again?

No, but I think i have it figured out. I hooked up my sisters H100i and I got about 30-40c. And when im listening closely I can hear the pump. So im 80% sure the pump is broken on my H110i. Ill send it in for RMA.

It's not the thermal paste or how it was applied, @fixitnow. Here's why :

when I feel the two pipes leading to the rad, one is cool, and the other is warm.

No amount of re-applying thermal paste is going to solve that (unless moving the tubes about accidentally de-clogs whatever is clogging up his cooler).

 

Only a few days ago, Jay explained to Jerry and the viewers how temperatures in waterloops work :

Starts at 1:34:00-ish, in case the timestamp doesn't work. 

 

Jay's very clear about it : the difference in water temperature before and after a GPU waterblock is 2-3°C at most.  GPUs tend to generate a lot more heat than a CPU, so the difference on an AIO will be smaller. 

A hot and a cold tube indicates that there's a serious problem with the flow of water, so either the pump has a problem or the radiator or tubes are clogged up.  Given that this is an AIO, the latter options seem unlikely. 

 

With the info we've been given so far, my money's on the pump.

Ok. I am only 15 still learning. I agree. Its likely that the pump is dead or that the rad is clogged up. Of its not under warranty and you are getting a new on try undoing the tubing and see if more then just water comes out.  You might be able to re do the tubing. Have a look at how Linus takes apart his water cooler in on of the two last episodes of scrap yard wars series 4. If it's still under warranty then take it back and ask for a replacement or a refund.

Sorry, I meant what method you use to apply your thermal paste.

I suggest you do it like this:

6- Spread the Thermal paste out, you want a thin coverage all over the CPU. This is to ensure that all of the CPU die is in contact with the cooler. If you don't spread it out well enough the the thermal paste will act as an insulator rather then a heat transfer method. If you are doing this to a laptop then it dose not matter if TIM goes on the green part of the CPU.

 

This is completely unnecessary. No one suggests spreading out the thermal paste anymore as it literally does not help anything. Just put a pea sized spot down and then put the cooler on it.

As I said that's how I do it and I get the best results.
