Is the i5 3570k running at 4.4GHz with temperatures exceeding safe limits?
Is the i5 3570k running at 4.4GHz with temperatures exceeding safe limits?
Hi all, I’m using an i5 3570k with an h100i GTX cooler and two sp120 performance edition fans pushed in front intake on an nzxt h440.
Current settings are 4.4GHz @ 1.28v, idle temps around the 30s.
After 30-45 minutes of prime95 blend test, I reached 80 degrees with one core hitting 85 degrees.
The AIDA64 Extreme system stability test ran for 3.5 hours, peaking at 75 degrees.
FireStrike Extreme also performed well, with each core staying in the low 60s during physics tests.
I’m also able to reach 4.5GHz @ 1.32v, where I hit 90 degrees after 30-45 minutes, compared to AIDA64 Extreme’s lower numbers.
1.) Are these readings normal, safe, or acceptable?
2.) Why does AIDA64 Extreme stay cooler and is that a more precise measurement?
3.) Is the extra 5 degrees at 4.5GHz worth it?
4.) Does my CPU sound like there’s an issue with the cooler?
5.) Could my processor be limiting the GTX 980 performance?
Thank you in advance for your help—I appreciate any feedback.
The temperatures are acceptable. Prime95 tends to push a CPU more than typical programs, but you won’t reach those levels while gaming.
They represent separate evaluations. I rely on RealTemp for my readings.
It depends on the situation. For gaming purposes, you likely won’t notice any variation. Tasks beyond gaming might show differences, though that’s still up to you.
1.4V appears to be the upper limit for this chip. Most designs stay below 1.3.
No. That CPU wouldn’t cause bottlenecks with two 980 Ti processors.
Edit: I own a 3570k at 4.3 with a Vcore of 1.112. Every chip behaves differently. You should first adjust the multiplier and then raise the Vcore once instability appears. Then repeat. So a stable clock at 4.5 with 1.28V isn’t guaranteed?
Intel Temperature Guide 3rd Generation 22 nanometer: i7 3770K / i5 3570K (TDP 77W / Idle 4W) CPU temperature = 67°C Core temperature = 72°C Maximum throttle temperature = 105°C Recommended maximum Vcore settings: - Core i - 3rd Generation 22 nanometer... 1.30 Vcore 1) Shouldn’t exceed mid 70s, really. 2) Try a small FFT with p95 v26.6 here: http://windows-downloads-center.blogspot...5-266.html for more accurate readings 3) Not recommended 4) You’re reaching the upper limit. 1.30 is the cap. At 1.28 you’d overheat most chips. Could also be a cooling issue. 5) NO

N3rdR4ge: Intel Temperature Guide 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 summary of the recommended maximum Vcore values: -> Core i 3rd Generation 22 nanometer... 1.30 Vcore 1) shouldn’t exceed mid 70s really. 2) perform a small fft with p95 v26.6 here: http://windows-downloads-center.blogspot...5-266.html to get precise readings 3) NO 4) you’re reaching the upper limit. 1.30 is the upper bound. At 1.28 you’re safe, but pushing harder could cause overheating. Could be a better solution. 5) NO barto: 1. These readings are normal. Prime95 tends to push CPUs beyond average usage. You won’t reach those levels during gaming. 2. These tests differ. I rely on RealTemp for accuracy. 3. It’s your choice. For gaming, you probably won’t notice the difference. Other apps outside gaming might. 4. 1.4V appears to be the chip’s cap. Most keep it below 1.3. 5. No. That CPU wouldn’t cause bottlenecks with two 980 Ti’s. Should I attempt to reduce the Vcore for the 4.4GHz? I tried at 1.25 but experienced a BSOD. Would that lower my temperatures slightly? I remain stable at 4.2GHz with a -0.055 offset, giving around 1.2v
barto :
1. Those temperatures are acceptable. Prime95 tends to push a CPU more than usual programs. You won't reach those levels while playing.
2. These are separate evaluations. I rely on RealTemp for my readings.
3. It's your choice. From a gaming standpoint, you probably won't notice any change. Tasks outside of gaming might differ, but again, it depends on you.
4. 1.4V appears to be the upper limit for the chip. Most keep it below 1.3.
5. No. That CPU wouldn't cause bottlenecks with two 980 Ti's.
Edit: I own a 3570k at 4.3 with a Vcore of 1.112. Every chip behaves differently. You should adjust the multiplier first and then tweak the Vcore once you hit an unstable clock. Then go again. So, would a stable clock at 4.5 with 1.28V be possible?
No, I attempted to reach 4.5GHz using 1.3v and it failed. I could only get it to work with 1.32v.
Reduce the speed to [email protected]; a 0.2ghz increase could add a few frames. Why waste energy on overheating when you barely get better performance?
