[Various] Intel Haswell Reviews - Page 56

post #551 of 858
TIM hasn't really shown itself to be the issue, it seems to be the gap distance between IHS and the die- when you delid and re-mount you naturally reduce this gap. People have done testing controlling the gap and comparing TIM's and whatever Intel is using tested out fairly well. Either way it doesn't seem like they reduced the gap on haswell so the issue from Ivy still is there.

Intel is at it's core a manufacturing company. They most likely moved away from soldered IHS for thermal stress/die cracking concerns @ 22nm, not direct material cost savings. A company like that doesn't want CPU's to fail in the consumers hands so that is their utmost concern (I believe that happened to AMD in the past).

Especially since you using a high end watercooling solution with only this attached.
If you want it for overclocking I advise to either delid it or to wait till the second revision which will have this fixed if it turns out to be real bad.
Will the second revision help the temps?

If anything moving away from a soldered IHS cost them more in RMAs from people who overclock and burn out their chips at high temperatures, or people who screw up delidding and get away with an RMA after super gluing the IHS back on.

But those are small costs compared to any issues caused that affect CPUs that go into OEM machines.

They will only change things if it turns out to be real bad if they don't think it is a problem they will keep it this way.

One more thing do you know when they will release the second revision?

Well I'll hold of on Haswell...maybe just trade in my 2500k for a 3770k. Probably will hold off on Broadwell too I'd rather get the new socket on the first release. I'm actually hoping AMD shows up with a good chip this year to bring the heat Intel. But man I wish I could grab that Mpower MAX board!

Xeons dissipate very little heat and are not overclockable. A lot of the sub 3GHz E5/E7 Xeons can be cooled passively. Shouldn't worry about delidding

E:

Not sure about the Haswell Xeons wrt straps though.

gz on haswell, invest in some nice CPU cooler and CLU for die-ihs.
