3770k Overheating Issue [65 degrees idle!]

Hi,

I recently build a new pc - Asus P8Z77-V Deluxe, 3770k, samsung 8gb ram, h100 cooler in push pull config with Geild Wing PWM fans (fans are plugged into mobo and controlled by asus fan xpert2), 6950 2gb, corsair 650d case with cooler master 200mm intake fan, IC diamond thermal paste.

Initially my pc was cool, it would idle at around 32-40 degrees and load at around 62-65 degrees. I did try some automatic overclocking with the asus software which i got a 4.3ghz oc.
A week or so after that the 3770k was idling around 65 degrees and load temps were around 75-90 degrees on all cores. I then thought i may not have applied the thermal paste properly so I removed it with thermal paste cleaning fluid. re-applied waited 10 mins (to cure/oxidise) then screwed the h100 back in place. At this point I have also rest all bios settings to default (no overclock)
This did reduce temps for a short time but the 3770k is now idling at 65 degrees again. I have checked the h100 cooler and the pump is defiantly working. I am really confused as I do not think air flow is an issue, no overclock is set, h100 in push pull should be keeping the cpu a lot cooler.

Any help would be much appreciated!
 
Checked the mounting bracket, I cannot see any damage.
The fans are in the correct orientation.
Even when fans are running at full speed:

it shouldnt be that hot,i did have a mb sensor bug in ai suite on a an asus z68 v pro but that got fixed with newer bios updates,if i were you id re-seat the cooler and makesure its tight but not over tight
 
Your graphics card seems to be running pretty hot as well. How is your cable management and fan set up? You say it may not be that but its always best to test.

Is your Voltage higher than normal under full load?
 
Ive just updated to the latest bios revision: 1504 still no change in temp.
My room was quite warm at the time I took the screenshot otherwise my gpu idles around 43-45 degrees.
Im not sure about the load voltage as its all on auto right now. But even at idle voltage (0.906) its still around 65-67 degrees.
The hsf feels warm but not hot. Also cable management/air flow is not an issue:

 
id try a full cmos clear aswell,leave the mb battery out for 30mins and then put back in/load optimized defaults and see what happens,still way to hot imo

another thing to try is set pc on its side and let it run overnight to dislodge any trapped air in the pump,then put back into upright position
 
In addition to the side idea, you could get the radiator and give it a shake and stuff there maybe air bubbles in and a little shake or rotate it a few times up and down with the pump out as well in hopes of releasing the air bubbles.
 
Ok, i removed the battery for about 25 mins put it back in, bios did go back to defaults but still no change in temps. I have now put my pc on its side and will leave it on overnight , tomorrow I will take the h100 out and give it a shake as suggested.
 
Could be a faulty pump btw, im not sure how you find out if its faulty, i.e listen see if its making a noise or what but maybe someone else can say more about pumps as im still new to watercooling and not even got mine in yet :p

Still, googled high temps and h100 and ive read about some bad batches about a pump problem so thats why i mention it, this was back in june or july tho.

After leaving my pc on overnight on its side and putting it back upright again all cores are now at 75-82 degrees when browsing the net......I will take out the h100 to give it a shake to see if that changes anything. I currently do not have a spare cooler to test with.

edit - i have taken out the h100 and given it a good shake, this has not made a difference at all. Could this be a faulty h100 or cpu?

You really need to compare with a different cooler but if anything is faulty it is more likely to be the h100 than the CPU. Is it possible you applied too much thermal paste? Also temps with the IC diamond get quite a bit better after a lot of use from my experience
 
About thermal paste you kinda made me wonder if u put it on right, i mean you said you left it on the cpu for 10 mins to cure or somit, why? You put a pea size amount in the centre of the cpu then put the cooler on right away, the pressure of the cooler will spread it in a circle evenly as shown in a vid somewhere on the forum as the best method.

So give that a go and if at all possible try the cooler on another computer or a friends comp if he has one and lets you just to see if its the cooler that is broke which tbh if the paste doesn't fix it im guess its the cooler thats the problem i.e the pump isnt working properly as its not pushing the water and there fore you probs have warm water hence the high temps.

That or you accidentally fitting the wrong brackets in the cooler i.e amd or a different socket 2011 or whatever and its not connecting properly i.e not touching the heatplate of the cpu properly (on the off chance of course).

Just some things to think about.
