Defective H100?

Alright so I have been waiting for this for a long time. I finally got my Phantom 820, and my H100 in, now I can start getting to high overclocks! :D 

I have an i7 860, LGA 1156 with a stock of 2.8GHz on a ASUS P7P55 WS Supercomputer motherboard. The volts are around .8 - .9v most of the time, and idle temp is average of about 30c. 

Before when I had my Hyper 212 Plus cooling my i7, I was able to reach a overclock of about 3.5GHz with idle temps around 35-40c on a EVGA P55 Le motherboard. 

Now when I get up to around 3.5GHz overclock my idle temps are around 50-60c with voltage around 1.3v. I want to just get to 4GHz but something seems wrong about these temps. Just for records it is around winter temps outside, and I did open my window, and my computer is right under my window, so it was pretty chilly in my room.

I don't know if these temps are normal, or if I need to switch out my H100, maybe my CPU is seated wrong? Don't know what I should do. Help?

If the H100 is new there is some break in period of the pump and the fluid. Water coolers usually take a while to achieve their optimal performance level. What thermal compound are you using? Are all of the temperatures taken at idle? You can use Aida64 to test what the temps will be under full load.

I'm using the paste that came with the H100, and it's been a few days. All the temps are at idle also. How long should I wait before I should consider taking action?

Around 3-4 days. That's how long it took for my H110 to begin functioning properly. You should contact Corsair directly and explain to them the problem.

Isn't an idle temp of 50-60 degrees fine? I mean, that's a badass cooler but I wouldn't start worrying until about 80 degrees at load

Its certainly not a temperature that will make the processor instantly fail but it is definitely higher than usually desired for idle.

Hmm...I'd take the H100 off, clean off all the existing thermal paste, re-apply a new coat, and re-mount the block. Maybe it just wasn't mounted correctly.

I have seen poor results with the 100i standard paste...

 

When you apply the new paste, put a pea sized blob in the middle of the CPU, hold (suspend) the pump/block above the paste & CPU as you attach it to the bracket clips so its not touching the CPU & Paste, then evenly screw each thumb nut 2 turns at a time until it seated, by doing this the pump block will be evenly pulled towards the CPU spreading the paste in all directions with no chance of air getting trapped...

I'll try that. I got some cooler master paste off of newegg for like 5$, so I'll try that. If not I'm just going fora custom loop once I get a i7 3820. I just want good temps until then. Thanks for the advice though!

UPDATE 

Just got like over 90 when only playing crysis 3 for a few mins. Here are some shots. Had H100 for a while now, break-in time should be done. 

At 1.35V those temps are about right.

You've gotta remember that's a huge overclock you're putting on that chip, with a lot of voltage.

Running at 4GHz at 1.35V on that chip is impressive, and I'd expect my temps to hit 90C on a H100 at that level.

Is it stable? Will it still be stable at lower voltage? You should test both of these things by running Aida64 stability test for at least 24 hours
