Well, I wasn't quite stable at that setting; P95 quit working at around 55 minutes of a 1 hour run. I just bumped vcore up to 1.17v and will restart P95 and see how it goes again.

So you say 80C at 4.5 Ghz at such low volts is not hot?, c'mon man get real, most SB chips runs 20-30C less on the core under load with those settings

Ivy Bridge isn't the same design broll. 3d Transistors, smaller process, better IPC all contribute to more heat.

Its not even more heat. It's less heat that can't be dissipated fast enough because of the smaller cores.

Maybe a little bit. But the biggest offender is the lack of using the fluxless solder process to bond the IHS to the processor die IMO. Instead they are using old skool (and cheap) TIM in between the IHS and processor die. I saw at least 15 C difference between the 2 methods back in the old Core 2 Duo days between an E6300 (fluxless solder process) and an E4400 (traditional TIM process). And in the years since then, I would imagine that Intel has probably refined the fluxless solder process even more, making for an even better bond between IHS and processor die.

You are spot on, problem is heat cant get away from the core effectively, that said I'm challenging the OP's statement, 80C is hot in my book and hotter than a SB chip running at 55C

anyhu....TIM is deff the offender. "3d Transistors, smaller process, better IPC" wont be the sole reason for the heat increase. It will most likely be a combo of the two, but ultimately they can solve the TIM issue by simply NOT BEING SUCH CHEAP ASSES!the latter is a bit more difficult.

have you tried IBT and see what are the temps?

As far as this thread, it's quite tempting to edit the topic title as it's directly saying that I'm a liar, which I don't really appreciate. Congratulations OP, you can run your four-threaded 3570K cooler than the rest of us can run our eight-threaded 3770K's. That certainly doesn't make those of us who have these hot running chips liars. Or maybe the water loop I run on this chip is inadequate compared to your cooler.

That isn't to say that what he posted was right/good at all, but just clarifying.

my temps are almost same except one core,using antec 920 cooler.

at load all cores are closer temps. just got mine yesterday, so have it set at 4.2 at 1.17v running cool so far,have not turned up the clock yet.

that seems to be after 2 minutes ( if that) your temps must have gone up by a fair amount after running prime for 30 mins +? The first two minutes of prime are not an accurate measure of load temps. Also core 3 is looking weirdly high :S

Cool, thanks for the info. I didnt realize Intel had any guys out on the forums.

NP Eldonko!

Just a general FYI, I've changed the topic title from "stop lying about ivy running hot." to "3570k Isn't Running as Hot as Expected". I think that covers the topic more succinctly and, more importantly, doesn't imply everyone other than the OP (with hotter-running 3770Ks, no less) is a liar.

hokie, I should be able to see how much easier the 3570K is to cool by tonight. I should have 1 being delivered from TD if UPS doesn't drop the ball today. And since I already have a decently clocking 2500K, it will be interesting to see what kind of temps I encounter, getting the 3570K stable at 4.7 like the 2500K is for 24/7 clocks. The 2500K had been benched on water up to around 5.4, and I have my doubts that heat will let me do so with the 3570K.

That's still about 20°C Higher than a 2600k same freq...

yer but have to member the IB will be about 5% faster, so lets say a 5% faster clock is needed, so 4.4/5 ghz to equal it performance wise, But even then the SB will run cooler. The IB would be beasts if they didnt run so hot,

Agreed, that's why I went for a 2600k.

i will be going for a IB when they bring out a new revision. Or might just wait for haswel. by then PCIE3 will probably be more widely used by then.
