4770k - what are the expected temps at any given voltage?

alex_123_fra · 23 Feb 2014 at 20:59

This is probably an impossible one to answer due to the crap Intel Paste under the lid.

My 4770k is at 1.25/1.26v fully stable at 4.5ghz. My temps vary from low 70s to high 70s under heavy 100% load on these using a corsair H80i aio cooler.

Reluctant to push more as don't want to venture in the 80s. What sort of volts/temps are people getting? I'm guessing due to the non-soldered lid, one person's 1.25v will give different temps to another's.

I would say you're on the limit personally.

Mine will hit the mid 90's in p95, probably shut down if i tried it now as ive upped vcore a bit. Mid - high 70's are fine. But as 8 Pack would say, don't use p95 etc on theese chips.

Glad my old chip/mobo is up and running

Agree, I only use cinebench and Asus rog realbench which represent real high workloads. Then I just game on it.

Yes thanks scotty, both were in pristine condition. My little h80i is doing ok but hard to resist not fully watercooling this rig as I've done with the others. Using it as mainly a media centre/living room gaming rig mainly though so maybe not worth it.

Glad you're happy - a nice loop may improve temps

But as you say, probs not worth it for what you're using it for

From what ive read/seen, custom water cooling doesn't make a significant difference over air cooling on hw compared to other Intel chips. Only by delidding and changing the paste to liquid pro/ultra will give very noticeable temp drops. 20c drop isn't uncommon from doing this.

At 4.5GHz, 1.30v in Prime95 'Small FFTs' I get 90 degrees within a minute. Supremacy Clean CSQ waterblock, one thin 280mm rad + one thick 140mm rad, but the processor hasn't been de-lidded.

Sounds too hot for custom. barely hitting 68 load at 1.3.

Lap the cpu and you get much better heat transfer frm ihs to block/heatsink. i will be lapping mine and pumping more volts this week.

Undesirable · 24 Feb 2014 at 01:06

Mine hits 60 something during blend Prime95, but not SmallFFTs.

It's just the luck of the draw tbh. Some may have a better paste application than others, or less of the black glue that holds the ihs in place. Ive thought about lapping and delidding mine, no warranty on it so that doesnt matter. But still wary especially about the delidding part. Ive lapped a few chips before, some benefited very nicely, others not just as much.

Me too, mine runs really hot, that's holding me back more than the voltage (which is nothing special either).

Also unlike ivy bridge chips, the addition of a strip of vrm's on hw also adds to the heat load. My previous 3770k, (4.5ghz on 1.34v) maxed at 81c in p95 small fft. Same case, cooler, fans and using liquid ultra paste.

@GoogalyMoogaly, out of curiosity what is yours clocked to and what sort of voltage? See from sig your on a custom loop too.

It's running at 4.3GHz @ 1.175v (It's mostly stable at 1.17v, but occasionally blue screens while video encoding).
I've not Prime95'd it for a while, but if memory serves it'll get well into the 80s.
Video encoding usually goes into the low 70s.

setter · 24 Feb 2014 at 20:56

Your voltage isnt too bad tbh, (1.267 here in bios, 1.2800 iirc at load). In games it will get into the high 60's, not helped by no airflow in my case. Benchmarks like xtu, asus real bench, cinebench etc will go to the mid 70's. Ive just uninstalled any synthetic programs like p95/ibt etc.

I don't own cinebench, ASUS real bench, AIDA64 or anything like that. I just use Prime to show me worst case temps so I know I'm safe when doing CPU heavy tasks like video encoding.

If it wasn't for temps I suspect your sort of voltage would get me 4.4GHz.

alex_123_fra · 24 Feb 2014 at 22:20

Tested a bit more and definitely maxing in the mid 70s at 1.26V with a solid 4.5GHz. I'm fairly happy with that I think and I doubt that it'll ever get to that temp in even prolonged gaming or media use (the PC's main usage tasks). I think it could run cooler still with some non-standard fans on the h80i attached to a fan controller but I'm letting Corsair link software automatically adjust things. Not really used to that as I usually only use fan controllers on my rad fans in other rigs.

Never lapped or delidded a CPU and I doubt I will get into that but I'm sure that would shave off lots in temps.

TJ Max on these is supposed to be 105 C. So I suspect even if one is running these at 90-95 C constantly (for example), even if close to throttle limits, it would still be fine?

mate on ts has his @ 4.6 and is 20c idling and 55c ingames. it was the 8pack bundle delidded and with liquid metal paste he uses cant remember name.

Sweet combo options there. Happy to say though that my combo of 4770k @ 4.5 (cooler H80i idling at 25C and max in games early 60s; stress test 70s) and Maximus VI Gene, cost almost half that. Courtesy of scotty

Yep, with the ocuk bundle your paying for a known good clocking delidded chip. Unlike when buying retail it's luck of the draw. Seems like you got a decent enough chip alex, mine was also bought secondhand.
