    Yeah saw that one.
    Although they used a poor TIM and left a large gap between the core and heatspreader, those are primarily responsible for the high temps.

    Actually, the TIM seems to be of very high quality. But it seems that they layer it on a bit heavy.

    You may be right.
    I'm not sure anyone has tested different TIMs while keeping the gap the same as the original.

    By replacing it, this dude got a temp reduction of 18C - http://www.youtube.com/watch?v=FirsCzTnbdQ

    I wonder why he didn't just try it without the lid. Any reason why?

    Haha brilliant, thanks for the link.
    So the distance between core and spreader is the main issue and the heat sink paste is excellent!

    -22.8C at 4.7GHz just closing the gap using the other paste.
    It looks like it should be even better if he could re-use the Intel paste.

    Can someone answer me, why is the lid put back on at all, wouldn't better temperatures be acquired if no lid at all is used?

    So it's the adhesive that's causing the gap between the IHS and cpu die? Well whatever the cause, my 3770k runs 17c cooler at full load than it did before the delid.

    To protect the core from damage.
    Putting too much pressure on one side of the heatsink by accident for example, could crack the core.
    Without the lid, its like the olden days of CPUs without lids, except the cooling requirements are now much higher and the heat density in the core much higher too.
    So a firmer contact is required which means more pressure.

    Also, due to higher pressure, defects in the coolers surface might now penetrate the core.

    To add to Mufflore's point the tests I've seen only show a 2C difference in temp so it's not worth it risk of not running the heat spreader.

    What about Linux? Does the bug happen there?

    My newly built 3770K is going strong.

    Poor Intel? Poor us! With AMD dead in the water, Intel are sitting around picking their balls. We were hoping the engineering samples were inferior to the final product, not superior cherry picked chips.

    Aren't the past 3 architectures all based to a greater of lesser degree on Nehalem, just with the added PCIe/GFX functionality?

    True. But no one outside the overclocking community is going to care about this. To them the CPU is working 100% out the box. Remember, we are the minority compared to Intel's target audience.
