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 @ 1.28v and my idle temps are in the 30's.
My temps after 30-45 mins of prime95 blend test were 80 degrees with one core maxing out at 85 degrees.
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 :wahoo:

1. Those temps are fine. Prime95 stresses a CPU out more than average applications. You won't hit those temps when gaming.
2. They are two different tests. I use RealTemp to measure my temps.
3. That's up to you. Gaming wise, you won't see a difference. Applications outside of gaming, possibly but again, up to you.
4. 1.4V seems to be the max for the chip. Most keep it under 1.3.
5. No. That CPU wouldn't bottleneck two 980 ti's

Edit: I have my 3570k at 4.3 with Vcore of 1.112. Every chip is different. You're supposed to change the multiplier first and then increase the vcore once you reach an unstable clock. Then repeat. So you don't have a stable clock at 4.5 with 1.28V?

Intel Temperature Guide
http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

3rd Generation 22 nanometer: i7 3770K / i5 3570K (TDP 77W / Idle 4W)

Tcase (CPU temp) = 67C
Tjunction (Core temp) = 72C
Tj Max (Throttle temp) = 105C

Here’s a list of the maximum recommended Vcore settings:

-> Core i

3rd Generation 22 nanometer ... 1.30 Vcore




1)shouldnt be pushing it over mid 70s really.
2)test small fft with p95 v26.6 here: http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html for accurate temps
3)NO
4)you are just pushing it to its limit. 1.30 is the max vcore. you are at 1.28. any chip would overheat when pushed that hard. might be cooler problem too.
5)NO

Should I try to lower the vcore for the 4.4GHz? I tried it at 1.25 but I got a BSOD. Would that maybe lower my temps a bit?
I'm stable at 4.2GHz at an offset of -0.055 Which results in around 1.2v

No, I tried reaching 4.5GHz with 1.3v and it crashed, i could only achieve it with 1.32v
