[TPU] Ivy Bridge Temperatures Could Be Linked To TIM Inside Integrated Heatspreader: Report - Page 29  

post #281 of 387
It's just that there is much less margin for error with contact for bare dies. Even a tiny spec absent of paste, or with an inconsistent waterblock base, can mean millions of transistors that are effectively uncooled (the silicon die itself having crappy thermal conductivity).

it's probably fine, given that it looks like there was plenty of TIM (though I would have tinted the block and spread it over the die, with the addition of a thin line down the center of the die to ensure complete coverage), but testing a few mountings to rule out such issues would be ideal.

Is this to be expected with Ivy Bridge-E late/early next year?
post #283 of 387
I doubt intel would do it CPUs that have high power consumption. IB-E is rumored to be a native 10-core so I think it's fair to assume that it's going to pump out a lot of heat.

post #284 of 387
I had a look at that hwbot forum, and I just cant fully believe thier posts. One thread is a guide to overclocking IB and it has screenshot of realtemp but the bottom half that shows max temps is blurred out by the taskbar, probably intentional. Also another thread says scaling on air and just says under load is 74C etc etc, but doesnt show a prime95 window or some other benchmark stressing the cpu.

Just wait until I get my hands my i5 3570K and I can tell you. Monday or Tuesday depending on the shipping time. Some of us will get it at Microcenter on day one.

Hmm im running caseless at the minute, so my temps would pretty much be as good as anyone who is running air. I think if i could keep it under 80c I would be relatively satisfied.

Who had problems with air cooling at moderate OCs?
I don't see anything in that sub forum that contradicts anything said elsewhere.

Here is the post he is talking about. Same temperature problems at high overclock still tho. At 4.6-4.7Ghz temps are fine, but once you go any higher the temperature climbs like crazy. Tho if this data is true, and if you can reach the standard 4.5Ghz of a 2500k on a 3570k without breaking the temps listed below. Then Ivy would be worth getting as for its core performance over Sandy.

When I said a few people, I didn't just mean that.

I don't see the word steel mentioned in the source.

The IHS is nickel plated copper.

Edit: The first source listed is a forum post and the poster says steel. This is incorrect.

The original Source is Overclockers and we said no such thing; because it's wrong. TechPowerUP! interjected that when they re-posted. As Blameless correctly points out, the IHS is made of nickel-plated copper.
