Quick Temperature check- i5 4690K

[Chronos5618]

Just wanted to quickly check with the fine members of this community that the temperatures I am getting with my new cooler sound about right, before I attempt any serious overclocking. Currently running Prime95 on a non-overclocked i5 4690K using the H105 and getting temperatures averaging out at about 60 degrees Celsius. Cheers!

That seems fine

Set voltage to manual and it will drop by 5-10C.

 

Also, never run Prime95 when not in Manual Voltage mode, or any stress test for that matter.

AH, ok! Why is this?

It pulls more voltage than it the CPU actually needs.

Use aida64 if you can

Adaptive voltage is like smart voltage, the voltage will increase and decrease as the demand on the CPU fluctuates. 

 

When you run a stress test, the demand on the CPU is pushed to 100%,and when you have adaptive voltage on while a stress test is running, adaptive voltage will pump additional(see:unnecessarily high) voltage into the CPU.  Running Prime95 in adaptive mode has been known to kill processors.  This is why whenever you stress test, you want to set voltage to manual so that a constant, unchanging voltage will be sent to the CPU.  Only after you have found a stable overclock, and you are done stress testing do you revert back to adaptive voltage.

 

Leave everything the same, but set your voltage to manual and report back with your temperatures, it should be much lower.

Is the temperature with enhance turbo on(all cores @ 3.9)? Temperature seems a bit high, probably because of prime95. If you are talking about 4.4- 4.5Ghz overclock with that temperature, then it's ok.

[Chronos5618]

I've set the core and cache to manual and ran Prime again. Still getting 60ish degrees if not a little higher, though they are not fluctuating as much. I'm not sure about the enhanced turbo- couldn't see anything like that in the BIOS. Oh, and the voltage is 1.071, if that makes a difference. Cheers again for the help

Try Aida64 or OCCT(free). Temperature is too high if the voltage is only 1.071v and stock clock . I run 4.6GHz with 1.213v, and 63.5C @ 22C ambient temperature, also with H105. Although mine is a 4790k.

Happy to help, take into account your fan and pump speed also, those being low will have a negative impact on performance.  The H105 is a great cooler though and can handle up to 1.3v and higher with relative ease, stay below 85C though.

I am using the H440 case. I don't know if it would make that much of a difference, but I know that the case doesn't have the best of airflow. Is there something I might have done wrong, or a setting I should be tweaking? My idle temp is 20-25, so I don't think it is a problem with installation, but I am all ears for suggestions!

What is the fan speed of the H105? 

[Chronos5618]

At max load it is around 1500rpm for me

[Deli]

Idle temp doesn't mean much. Try to clean the thermal paste, re-apply new one and re-install the pump block. Could be a small air pocket between the CPU and the block. 

 

I run 1200rpm max with NF-F12. But Corsair SP120 is almost just as good(tried it, set it at same rpm). At 3.9GHz, you can expect 55C or lower. 

 

People warn not using P95 for Haswell. So I've never tried it on my CPU. Try OCCT or Aida64 to see what the temp is. 

[Chronos5618]

Forgive me for my ignorance, but I have been using the FFT setting on Prime95. When I run it on blend, OCCT or AIDA64 I get temps of 45-50, which seems more reasonable. Not familiar with all this testing lark- normally just leave it on standard and be done with it.

According to more experienced forumers, P95 has not been updated for Haswell architecture. Intel, as well as many experienced members here, recommends Aida64. 45-50C seems good.

 

Forget about the result of P95. Go ahead and overclock the hell out of your chip. Have fun.

Prime95 is arguably the most strenuous test you can run to test for stability.  Because of that, it has the highest temperatures, and finds instability very quickly.  I personally don't recommend running P95 for more than 20min because any stability problems will likely be found within the first 5min anyways.  When you run Prime95, and any stress test, you have to set your voltage to manual.  P95 has gotten a bad reputation with Haswell and DC because people don't know any better and run the program without changing voltage and they kill their chip.  Set your voltage to manual before stress testing and you're safe.  When you are done testing, and have finally found stability, then you can revert back to adaptive voltage.

Sounds good to me So if I find a stable overclock and switch the adaptive voltage, the maximum voltage that the chip will receive will be the voltage I manually set beforehand, but if not necessary it will receive less due to the adaptive setting?

[Trik'Stari]

I got mid 50's from prime95 after about 15 minutes. Right now with a few things running, I'm sitting at 19 degree's C according to Gigabyte's hardware monitor. Not sure if that's right, but I'm only running it at stock voltages and clocks.

 

Then I read about the "dont use prime 95 on haswell" thing and immediately shut it off.

Yup, think of it as smart voltage.  It scales as necessary. 

 

For instance:

 

My i5 is overclocked to 4.5Ghz @ 1.2v right now  I am running adaptive mode.  Right now because I am just typing and nothing else, my voltage is hovering between .719 and .902 and Mhz is between 800 and 3000.  It scales as needed.  If I were to launch a program that requires 100% CPU usage, my voltage would go up to the 1.2v maximum that I set, and up to 4500Mhz.

Prime95 is perfectly fine to us as long as you set your voltage to manual before running it.  Any stress test should be run with manual voltage, but especially P95.  I like P95 because it is one of the most harsh tests, and instability will be found quickly, within 5 minutes.  When I run P95--when I run any stress test, I make sure to set voltage to manual and then I go into Custom and the only thing I change is Time to Run Each FFT Size in Minutes to 3.  This way it will cycle through more tests in a shorter period of time.  I never run P95 for longer than 20min.

 

The reason Prime95 has a bad reputation is because people don't know to set their voltage to manual before stress testing and end up frying their chip.  It is not Prime 95's fault, it is user error.  PIFOTC

I'm too scared to mess with voltages lol. I can't afford to mess anything up because I need this PC for school. Unless someone makes a video guide on how to overclock with Gigabyte's z97 bios for my specific motherboard, I'm not doing anything lol.
