i5 3570k / 4.4GHz/ 1.26v Temps too high?

post #1 of 15
Thread Starter 
Hi all, i currently have an i5 3570k with an h100i GTX cooler running two sp120 performance edition fans in push as front intake in an nzxt h440.
I am currently running 4.4GHz @ 1.26v and my idle temps are in the 30's.
I ran prime 95 for 1 hour and the temps were as follows:
min: 37, 27, 29, 35
max: 79, 84, 79, 85
I also ran AIDA64 Extreme system stability test for 3 and a half hours, and the highest temp was 75 degrees.
Also, I ran FireStrike Extreme and during the physics test, each core was in the low 60's.
And one more thing, I can hit 4.5GHz @ 1.32v and the max after 30-45mins of prime95 blend is 90 degrees, while AIDA64 Extreme being lower.
1.) Are these temperatures safe/reasonable/normal?
2.) Why is it that AIDA64 Extreme is reasonably lower, and is this a more accurate temperature?
3.) Is it worth it for the extra 5 degrees to go to 4.5GHz?
4.) Do I have a horrible chip and does it sound like there is anything wrong with my cooler?
and
5.) Is my processor bottlenecking my GTX 980?
Thank you very much in advance I appreciate any replies thumb.gif

- Your temps are perfectly fine.
- Aida64, I have no idea. I personally don't use it.
- 5 degrees for 100mhz... Sure, why not since your temps are good anyways.
- No, your chip is fine. Most of the temps your seeing is from the TIM. Delidding w/ CLU would net you easily a 10c drop.
- No, your 4.4Ghz 3570K is perfectly fine with a GTX980.

Don't worry about Prime temps. That's an unrealistic load put on the CPU. More often than not, your never going to see anything other than benchmarks / stress test's pushing temps up that high.

#1 - Maybe. Reasonably safe yes, normal maybe not.
#2 - Aida test is very different. Prime uses instruction sets in different ways that can draw more power, which makes the CPU heat up more. This doesn't neccesarily make a test a better overclock tester as power doesn't correlate that well to stability, but prime is generally much harder than Aida.


#3 - Maybe, depends what you want and how you're using the CPU.
#4 - seems pretty normal CPU, but hot.

To specifically answer a few things, i'm curious of your ambient temperature and motherboard. If your room is 17c, you'd expect a much cooler CPU than if your room is 27-37c. Some motherboards in that CPU generation are known for inaccurately reporting Vcore to be much lower than it actually is, which can lead to oddly high temperatures. One of the worst offenders is the Asrock z77 extreme4.

Depends on the task/game. Some are CPU light to the point of being effortless to run on practically anything modern, others are so CPU heavy that they will bring the best CPU's to their knees and not challenge a 980.

Hi!

1. Temps sound reasonable to me considering your chip, cooler and voltages, assuming youre at 20-25 C room ambient.

2. Aida 64 Extreme doesnt heat up your chip as much as Prime does, not many other prgrams do other the Intel BurnTest/ Linx. Prime 95 is considered the hardest stress test to pass, therefore if you can pass Prime 95 for 24 hours theres a very good chance its completely stable for anything you can throw at it.

3.Thats subjective to you. I've been running my chip at 1.32 volts stable for over 2 years, and unless youre doing huge amounts of CPU work your chip wont hit anywhere near those temps in gaming. I dont usually go over 65c in games, I hit around 85c on my hottest core in Prime at my current settings.

4. Its not as bad as my 3570k, which does 4.4 ghz at 1.32. Mine needs 1.4 volts to boot Windows at 4.5 and be anywhere near stable So yours is not the best, but not the worst. I think I have that 'honour' from everything I've seen. redface.gif

5. In some situations whatever you do the CPU will become a bottleneck. It depends on the application/game. I'm running a GTX 980ti with my chip and the most demanding games I have such as Witcher 3 and Dying Light run a huge amount better then they did on my old GTX 780. If the CPU was limiting me, I wouldnt see any improvement at all. Something like Battlefield 4 multiplayer, Starcraft or Total War games for example would see an improvement from a faster CPU, but it wouldnt be a huge improvement overall going by the benchmarks I've seen.

Liek here : http://pclab.pl/art61577-8.html



EDIT, Ninja'd by Cyro. Good point on the motherboard, this doesnt sound like one of those though, Ive seen people reporting those kind of temps at a supposed 1.2 volts on an Extreme 4 with similar performing coolers.

OP You also dont mention if youre using a PWM preset setting or fans at 100% on your cooler. smile.gif

Well I think this proves pretty well how bad AIO coolers are if they can't even handle 1.26V.
If these are "normal temps" like people here say. Way too high if you ask me for such low voltage though. A 25€ air cooler can reach those temps easily.

Ivy in general runs hot. It's not that AIO's are bad, it's just the fact some CPU's run hotter than others. Ivy compared to previous gens was a huge jump in temps. The only thing that actually helped me with my 3570K (because it ran hot as hell) was de-lidding, and CLU. After that it ran 60-70c max under IBT with voltages varying between 1.4ish to as high as 1.55v. Custom water loop cooling.

I think these temps are a little high, but not way too high. OP still has not listed ambient temps though. Perhaps a re-seat on the CPU cooler?

My R1 Ultimate is hitting 85 C in Prime at 1.32 volts at 22c, and when I had it at 1.26ish for 4.3 its around 80 at about the same ambients IIRC. I dont mind my chip hitting 90c in Prime as it never gets anywhere near that even if I fold on the CPU.

We're talking about non delidded chips here not under custom water loops smile.gif

And no a 25 dollar air cooler couldnt hit those temps at these voltages, I had one and it was significantly hotter then my R1

Reseat never hurts though, never know your luck, but also as I stated he could be running the fans at 50% we dont know yet.

2nd Edit:

As an example R1 Ultimate with a pair of 1300rpm Thermamalright TY147's IBT right now if that helps. I was going to reseat soon as I've been messing around in the case changing things up a bit anyway, but I dont see that much difference from what Ive always got.

Those temps are normal for ivy under stress..I run my 3570k at 4.6 ( 1.304v) h110 I hit 70s to a max of 77 under prime 95..gaming doesn't break 65c..you're not bottlenecked with the 3570k unless you're trying to get framerates as close to 144hz in demanding titles that's the only place where a 6700k etc would benefit ..60fps gaming 2500ks are still fine

Hey everyone, sorry, I did not know that this thread would get this many replies. biggrin.gif
My ambient room temp is I think 20-25c, I think. I am not too entirely sure.
I am currently at 1.28v 4.4GHz (found to be the most stable) and I played GTA V for a few hours and the temps never really went above 60c. Usually in the mid/high 50's.
I am thinking of adding 2 more fans (nzxt fn v2) in pull to help pull more air into the case, with the SP120 Performance in push.
My motherboard, by the way, is an Asus Sabertooth z77. And the strange thing is, I was never able to get above 4.2GHz on my old board (Asrock z77 Extreme4)
With 4.4GHz at 1.28v the highest core temp in prime (monitored by realtemp) is 85c. Some other cores being around 78. So I'd say 75-85 depending on core.
At 4.5GHz the highest a core will hit is 90c.
I was thinking that there was something wrong with my cooler, until I talked to a friend and read your guys' replies. The pump shows that It's running at 2,850 RPM in corsair link
And I have the fan set to performance mode.
Also, one more thing, is that while playing the Witcher 3, I felt some warm air being expelled from the back of my case, is that normal?
