Just to update everyone who is new to the post, I think it is the way I put the pipes into the CPU block thanks to rich for pointing that out.

ivybridge temps go skyward with more volts because intel put cheapo crap tim between the die and the IHS.

You may have a flow issue though. Is the loop fully bled of air? (e.g radiator airlock)
 
I think It is fully bled, It was leak tested for 24 hours, every so often I turned it off and rocked it around and listened to how much air came through when I turned it back on, After a while there was almost no extra noise when I turned it back on.

+1, l had a black ice stealth 360 cooling a i7 920:4.2GHz+470 overclocked the hotest the cpu cores got was about 75'c running prime.
 
Are you drawing in cool outside case air through it or warm inside the case air through it?

Warm case air wont cool radiators
 
You may have too much case pressure so the increased fan speed does not deliver additional air flow. What if you reverse the flow?
 
I am not sure about reversing the flow, I cant test right now because one of the SSDs in my raid array just died...YAY. All i can say for the air flow is you can feel the air flow increase when you increase the fan speed, its quite noticeable.
 
Bad mount then. Idle should be almost room temp. So if your idle is 40 your load temp is maybe ten degrees higher than it should be.
 
The rad is more than capable. Your loop is nowhere near overloaded and that is why increasing fan speed is not going to remove much extra heat from the loop, lowering water temp and therefore cpu temp, as it was already optimally achieving it.

So it is either a bad mount/TIM/block or just the cpu. Another possibility already mentioned is flow.

If you're interested ther's great info/data on this site http://skinneelabs.com/hwlabs-sr1-360/4/ That links to the sr1 review, with data about is heat dissipating characteristics but theres also group comparison data for rads (of diff fpi and at diff fan speeds) to be found there too.


Also, too late now, but you'd probably have been better off with AF fans if quiteness was your goal, as they will move more air at quieter rpm's than the SP. Static pressure is more important for med-high FPI rads. But regardless, don't worry about it as they'll get the job done more than easily enough and in my experience, at lower rpm, good static pressure fans can be very quiet. And if you're getting rid of the heat fine anyway, there wont be much to gain perf wise.

I assume it is the block, something is clearly not quite right. Does any one know If I can do the thermal paste with the case upright, I normally just stick the case on it's side but it's not really possible now.

Of course you can, I did mine like that last week.
 
Also, what block do you have?

Edit: just realised you have an EK block. Do you have the flow going the correct way through that block? it must be input into the centre hole of the block and outlet to the outer hole of the block.

Well ****! Don't suppose there is a way to switch these without draining the entire loop?
I am thinking removing the block and trying to hold it above the case when I remove the tubes.

Just to be sure for you here's the fitting instructions. Not sure if all blocks from ek are the same so please do check on their site

I fitted mine wrong way round when i built mine first time around.

Change the flow of your loop at the pump end, that's what i did. Otherwise, no, you'll have to partially drain and switch them over.
