So where does all the heat come from on these? Those temps are worse than SB-E.

Hi all first post.

Its not a case of where is all the heat coming from, the problem is the heat energy getting away, or rather not being able to. This then leads to localised temperature increases. The smaller die, and the smaller decrease in die size has led to a greater watts/mm2. hence meaning that the contact with the cooler is the limiting factor (or more likely the contact between the die and the heat spreader), the cooling system that sits beyond that contact point is probably doing less work because of this, and if there was good contact would be doing no more work that normal. So the expense in the cooling system has to be applied to that point only, the biggest rad in the world won't help.

Is it possible to measure water temp rises, and that should prove that this is the case, i.e. the same or less energy is being transferred into the cooling system, probably tricky to measure as the deltas would be smallish I think.

Big thanks to eggy88 and punceh, really enjoying this thread. Will be upgrading to a 3570K from a Q9550, not OC'd before (well once for about 5 seconds before the mobo went pop), only aiming for 4.3/4.4 want pci-e 3.0 for when I upgrade to GTX7XX i alternate cpu and gpu upgrades.

wow that means you need a 0.16V overvolt compared to mine and its not even stable blinksmiley.gif
i been thinking, you got your chip from ebay from china right? is it an actual chip thats going retail for sale or they might have been meant for OEM builds? maybe thats why its lower binned or something?

another person experiencing similar (perhaps not quite as bad) issues.

http://forums.aria.co.uk/showthread.php/100021-3rd-GEN-Intel-CPU-Semi-Stable-Testing-*Preview*-56K-WARNING

Any thoughts on whether the Asus Z77 V or the V pro is enough for getting to 4.3 ish? its not using that much power, just getting a bit toasty whilst doing it.

The Ebay ad says it's a retail OEM chip yes, so it could be lower binned yes.

Just found this, i'm tempted to pull the plug on it to have another one to test, but i'm doing LN2 on Wednesday so it will not get here before that, so there is no point. Also the price is 89$ more then what i payed for my chip, and it's a pretty close batch number.

Lol at the gaming adds on the ebay listing for the chip. Doesnt look very legit tongue.gif
