Corsair H100i & i7-3770K STOCK Really High Temps

I'm running an i7-3770K at STOCK speed cooled by a Corsair H100i with SP120 Quiet Edition fans in push. All this is inside a Fractal Design Define R4. At idle, the CPU was doing 40C and when gaming it was going past 80C. These temps are safe (just) but I'm not confortable with them. So I checked the backplate (common mistake for H100i system builders to get the backplate orientation wrong) and it's fine, checked the thermal paste, thats fine also, I then replaced the thermal paste - temperatures got worse. As I write this the CPU is at 45C and when I tested a gaming load it hit 100C, really bad temperatures for a STOCK CPU with an AIO liquid cooler. I'm using Arctic MX4 and using the small blob method to apply the paste which when I did a test application was getting a decent spread. My GPU is a REFRENCE GTX780Ti so it's not like the GPU is blowing hot air into the rest of the case. I'm completely out of ideas so if anyone can help it would be much appreciated.

Did you plug the pump into the CPU fan header? (You should have if you didn't, and try increasing the pump speed to see if that helps.)

Is the pump on m8?

if your temps got worse by swapping thermal paste, you're doing it wrong.

 

from experience the pea method is a rather difficult method to get the right amount.

 

personally, i had great success with the X method, it lowered my load temps by 20% after having the pea method first.

There is a fault with some h100i where the cpu block doesnt always make contact with the processor, to fix this i put some plastic washers on the back so it ensures the pressure is made.

Yeah the pump is on the CPU header on my board and the two fans go to the pump which also has a SATA power to it aswell

Is the pump actually making noise? i.e, is the thing actually working?

You must have been heavy handed with thermal paste mate. 20% drop in load temps by re-application is a bit much :l

Okay, So that will bring it closer to the CPU? Looks to me like it would bring it further away but it's hard to visualise. Will any wahsers do or must they be thin or?

Yeah I can hear the pump and the tubing feels cooler near the rad than near the pump so there must be atleast some heat disipation

 

EDIT: it is dificult to tell exactly though with a noisy refrence cooler :)

do you have any give on the cpu block, these washers are there as the screws on the stand offs are too long, this way the standoff is pulled against the mobo vs sitting above it.

i guess i was a bit greedy on thermal paste the first time (an easy thing to do with the pea method)

 

the second time i also was more careful to screw my ungodly annoying cooler on perfectly straight. not sure if i had it on an angle the first time, but it seems to be better.

Yeah but it just feels like the motherboard flexing TBH. Thanks for explaining the washers system.

Not sure what difference this makes but glancing at Hardware Monitor cores 1&2 are the same temp whilst core 3 is 2C warmer and core 4 is 4C cooler. It has always been like this so maybe it is the mounting??

Your profile says you got the Extreme4, if have that board so if the washers worked for you it might just work for me, hopefully..

The PCB is pretty much the same though, actually socket area looks completely different after a Google search, I'm out of ideas :D

Anyways thanks for the help I am gonna have to leave it until tomorow hopefully it works.

So I've done the washers mod and it has improved the contact, I've also re-done the thermal paste for an even spread and STILL as I write this it's running at 45C. Any more suggestions?
