stock 3770k temperature with hyper 212 evo

[im1knight]

Hello, I know there are multiple posts about this, and now that 4770k is out, that became the majority of the focus. But I have got myself a 3770k system last week for a cheap price from microcenter, and I'm experiencing temperature problems with everything on stock settings.

First being that my core temperatures vary a great deal. I know that at idle temperatures, it's probably not a big deal if the temperature vary due to inaccurate sensors. But cores still have a big temperature gap under load, which is a bit concerning.
at idle, my temperatures are(room temp about 26-27C):
Core0:40C
Core1:42C
Core2:33C
Core3:30C

with prime 95, after temperatures stabilize:
Core0:70C max
Core1:71C max
Core2:64C max
Core3:61C max

Playing games (GTA IV, FSX) I'm at mid 60s mostly, with occasional peak into 70. (Yea..as high as prime 95 temperatures, but with highest reaching ~70, and lowest at ~49, that is a whooping 21C difference)
This is with a hyper 212 Evo, with one stock fan. Temperatures checked with coretemp and Realtemp. They showing the same temperatures.

I'm also observing some rapid temperature fluctuations on core 0 and1, such as going from ~48 to ~62 in one second, then returning to ~53 the next. Initially from experience this indicates a bad heatsink mount/uneven spread of TIM, but I have reseated the 212 Evo at least 6 times now using Arctic Silver 5, with absolutely zero improvement, I tried both line method and pea method. When I take the cooler off, arctic silver 5 also appears relatively nicely spread out...

Now I've seen other people with my temperature with a 212 evo and 3770k, but most of theirs are overclocked to about 4.2-4.4ish. Mine is actually sitting stock with default turbo up to 3.9.

I also have an ivy bridge i3 system. i3 3210. That one with INTEL STOCK cooler is running 32C idle and 53C under prime95. I know i7 is supposed to be hotter than i3, so no complaints there. But by this much? And with aftermarket cooler? My core 2 and 3 seems to be relatively in the same ballpark as the temperature i'm getting with the i3, but core 0 and 1 are just SMOKING hot. I'm thinking of a mild overclock to about 4.2, but with this kind of temperature i'm not even going to think about it without figuring out what might be the problem here.

Thanks!

yeah, but you're still within operating temps. Besides, you can use the heatsink as a frying pan. Welcome to the forums

Thanks for the welcome

my main concern at this point is not frying the chip, but my overclocking potential due to this high temperature. The reason I posted this is because other people with the same chip seems to be achieving a lot better temperature with theirs?

What speed are you running the fan at on your Evo cooler? On my 212+ cooler i run the fan at max speed (2000RPM) instead of the normal 600RPM and it's significantly cooler although slightly more audible.

I set the mode to Turbo in the bios setting, right now it's running at ~800rpm when its idle at 1.6Ghz, and upwards of ~1800 at prime 95.

And apparently, a Phanteks PH-TC12DX is only $50.

IMO that is all perfectly normal and to be expected.

The across-core temperature variation is unavoidable because the die itself is not symmetric. And the temperatures are a lottery, it all comes down to how big (or small) the gap is between your die and the IHS.

Intel doesn't seem too concerned with making this gap a critical engineering care-about. So you end up in a lottery there

I am running a 3570k which probably runs slightly cooler than a 3770 because no HT .
Now for example here my room temps are generally around 73-74F (23c) and running prime95 (latest version 27.9) I get highest temps of around 62c , thats at 3.8ghz .

Its totally normal for core temps to jump around and have a delta of 7-10c .

Case cooling is going to have impact to with prime95 , you need good airflow through case .

That not really fair as the CPU in those test are a 3960x (Sandy Bridge-E) , six core 125TDP . where 3770 is 77w TDP ,212 evo handles i5/i7 37xx fine upto mid OC (4.5) .

Thanks Ed1, that really helps me seeing my temperatures in perspective. I just finished running prime 95 with my HT turned off, and sure enough, I got around 66-67C, with a single spike into 68, which is expected since my room temperature is about 4C higher than yours, and i'm running 0.1Ghz higher. But with my current temp I'm not sure if it can handle 4.5...I think I would be looking at low 90s if i made it to 4.5Ghz...What defines "handles fine"?

So basically I got unlucky and got a chip with a big gap? Damn....I'm already out of the exchange period for the CPU and motherboard, should've returned it and hope for better luck on another one... But I'm still in the period for the cooler, so if there is a better alternative, i am willing to try...Btw motherboard's auto voltage is giving me ~1.25v at 3.9Ghz, and ~1.06v at 1.6Ghz idle. Not sure if it's too much? I have already set a negative offset voltage in the bios and left it on auto.

The phanteks cooler only got like 4 reviews on newegg, and I have never heard of it before...not sure if its a good idea? If airflow is important, would it help if I grab another fan to form a push/pull config on the hyper 212? Currently in my CM RC690 case, I have 1 front intake, and 1 rear exhaust and 1 top exhaust fans, all 120mm. I can still add another exhaust on top of the case and 1 intake on the bottom.

EDIT: I just tried using the turbo to clock to 4.1Ghz, and the temperature immediately went up to 77C on the hottest core. 7C rise on 0.2Ghz...How do people manage ~4.4Ghz ish on this cooler..?

People like to forget about checking for throttling.

People also like to bench at 72F ambient or below.

People also don't make allowances for people with bad case airflow.

If you want 4.5Ghz on 3570k or 3770k, the minimum you want to use to be sure is a Thermalright True Spirit 140.

Ever chip is slightly different as they don't all have same VID , so some run hotter or cooler depending on voltage needed . Then you add in space and mounting of IHS gets more variance .
I would not bother to try above 4.6 for sure with evo . I meant more it can go somewhere around 4.3-4.5 say with temps around 85c , now that is just from reading as I myself don't push it and no need to as I like cool temps .I personally would not go above 70-75c .
I haven't OC the 3570 much, just raised it 200mhz on auto with minimal voltage and temps changes . you will hit a sweet spot "around" 4.2-4.3 or so where it should still run on low voltage and temps then as you move up the voltage will need to be raise more than before ,and hence temps will go up a lot .this is where evo will struggle FWIU .

Oh, I use 500r case which cools nice , my CPU and vid are cool , it very open case though .

Well there is one thing about the EVO: the stock fan is shit! I replaced mine with Noctua NF-F12 PWM, and it got a bit better.
However, since your CPU is not delidded, I would say those temperatures are fairly normal (perhaps a little bit higher than I would expect, but still ok) if everything is at default settings.

Really ?
What was problem , noise , performance ?
Did you setup a fan profile in Bios . I found stock profile gave around 500rpm at idle an only 1100-1200 or so at load . Changed that so I get 900-1000rpm idle and 1800rpm max .

I did notice after about 1500-1600 not much improvement came .

How much did the NF-F12 give , its kind of expensive (25$) to bother to put on 35$ HS IMO , unless it gives decent improvement .

 

[taq8ojh]

Noise being the worst, but also the performance. I can run the Noctua at lower speed to get the same result.
1100RPM is enough to cool my CPU at 4.4GHz (delidded though). It's also absolutely quiet. The stock one was like bzuuuuuuuuuuuu!
I use PWM setting for the fan, and silent mode.

Ok, maybe you got a dud or I got good one . I do see many reports CM 120 PWM fan is noisy or craps out .
Thing is they are cheap to replace .

Just thought I might want to bring an update to this topic.
I have overclocked the chip to 4.2, and replaced the stock fan with Xigmatek XAF-F1255 fans and did a push pull setup, and oh boy what a difference. (Both in terms of performance and noise)

Now i'm sitting at 68C with prime 95 with overclock to 4.2 when the fans are at 100%. When I was using the stock fan I was sitting at 75C. And these things move serious air...except they are extremely loud under load. (Their 28db claim was at idle maybe..) At a more reasonable noise level, I got about 70C under prime 95, and highest spike of 65C under FSX. Most of the time stays in the mid 50s.

The one big problem facing me now is that these fans are way louder than the stock. And whenever my CPU temp spikes(from 40C to 55C in a second), the fan would rev up, and then rev down, since this happens a lot during games, this reving up and down gets kinda annoying. It sounds like someone is flooring the gas pedal in a car for like 3 seconds, then let go of the gas pedal, only to repeat seconds later.

First I'm not sure if this constantly changing of fan speed will shorten the life of the fan at all? They are about 15 bucks a piece, not that it would break my wallet or anything, but I'd rather they last a while...If it doesn't affect the fan's life, i might just grow used to it...

If it does, is there a way where I can manually set a constant RPM for the fans to run at? I can't find such setting in ASUS bios(p8z77-v pro). The manual mode is just setting a temperature where the fan will be running at 100%, which still causes the reving up and down of the fan.

Thanks.

(And also it seems I got one of the lower 3770ks... 4.2Ghz@1.19v is as low as I can go. 4.3Ghz@1.2v causes prime95 to crash...-___-

If you install the Asus AI Suite, you can use the fan tool to max out your fans.

I tried that approach, and it worked. Except for some reason after installing the AI suite, my system boot time went from under 5 seconds(ssd) to over 2 minutes. It would just hang after the login screen...with no programs loading. Then after the Asus software kicks in, everything loads up in a second..

Does constantly varying fan speed hurt the life of the fan at all? If not I guess I would just deal with it. Guess just gotta turn up the sound more. Boot time impact like that is ridiculous. And it seems that its the fan expert that's causing the slow boot issue after some search online...
