HeatKiller 3.0 @ 87C WTF?!

So how do I get rid of it?

Open the block, confirm nothing is blocking the path.
Re-install twice, confirming the TIM spread. Double-check no caps are preventing a good contact on the chip.
No kinks in tubing.
Fill, then bleed system of air by rocking your case sideways, being careful about the rad specifically. This is where most of the air gets trapped.
Make sure the pump is always fed with liquid.

This has to be a pretty damned big air bubble inside the block, haha. I say give your system a good shakedown, it might be easier to dislodge the bubbles this way if you don't want to take your block apart.

I would do like others say, open the block to see any gunk or dirt. Second I would take down the whole loop and re-do it. I would mount the res up top near the rad, the second psu option in the case. That way, you're pump is still below.

But the block does seem at fault here, either it had dirt inside and is blocking flow or it's not mounted properly/tightly.

Does anyone else have an i7-860? Mine idles at 40 and gets up to 85-90 as well. It's been folding 24/7 for 2 months now without any issues.

Those chips just run hot...

My guess is a huge airbubble in the rad. Try tipping the case on it's side with the pump running.

And FYI, my i7 920 D0 with HK, 655 pump, and feser 360 rad runs at 63-68 degrees loaded at 4.1Ghz and 1.3V, HT on.

When the water go out the rad, it get inside the cpu block in the middle, and since the outlet is at the bottom of the cpu block, the block is only partially fill. They are no presure from the pump after the block, only a drop to the reservoit , so of course it will never fill ( the Op should at least reverse the block to make it outlet on top )
In a setup, where the rad is on top , the outlet of the rad should go directly in the reservoir .

860s don't run that warm.

At (stock) it idles around a very inaccurate 20C and loads at around 43C.

Even with nearly 1.4V running through it, LinX pushes the CPU to ~ 80C full load. Nothing to be worried about.

air rises, turn your system about and try and make sure the rad and the cpu block are not the highest points in your system and the air will move out

If the led display on your motherboard is showing the cpu temps, its only 28C. Maybe there is a problem with the programs you are using to read the temps.
