    Pull your IHS off a core i7 and prove us wrong (not that hard, I have removed soldered IHS's before) , only shoot a youtube video of it working, if you want to seemingly defy physics and expect belief, you have to show proof. I have youtube videos of a thermocouple in IHS and one directly in the die via drilled holes in IHS and drilled into die, showing actual gradient through IHS and dies, posted in realtemp thread. So you can easily make a video after you pull the IHS off showing both the setup and temps/screen all running and prove it works...screenshots are easy to fake, not that I have even seen a screenshot of any successful direct die cooling.

    I am not pulling IHS off on my i7, as I know what will happen when trying to merge 666 lanes of traffic into 1 lane. Yes the cars could all drive incredibly fast...but speeds would be unrealistic. If you think you can compensate by theoretically running water fast enough, I would suggest you start with this pump . As to how to find a waterblock that wont rupture or keep die from cracking under that pressure, I will leave to you.

    trueg50, as for simplifying the process down to core>water, you are ignoring surface area.

    Direct die = 10,000 cars (heat) in parking lot A drive in single lane to parking lot B (water) at 1 per minute (represents slow .5w/m*k transfer water). That is simplest transfer via shortest route, and the rate limiting step occurs immediately (but low surface area for transfer).

    IHS/waterblock = 10,000 cars in parking lot A drive in 160 lanes or 160x fast (160x represents rate tim1/solder vs water) then those speed up to 300 per minute (copper IHS) as lanes widen/go faster, then across tim2 at now still 50X faster than water (surface area increase x tim2 (3-6W/m*K), then through copper water block again 300x fast, then finally through 1 per minute now slow water, but x 1000 lanes (massive surface area of waterblock copper pins) = 1000 per minute to lot B, ie here is where surface area disagrees with your rate limiting arguement being same regardless of where it occurs.

    IHS/Waterblock heat (cars) has longer to go to get to parking lot, but guess which parking lot empties faster?
