CoreTemp for i5 4690k

[HerpinTheDerp]

Hello everyone! So I've finally finished my build. Here is what I've put together:

i5 4690k w/ H100i

Asus Maximus VII Hero Z97

EVGA GTX 780 Ti Classified

Crucial BallistiX Tactical Tracer Red 8GB(2x4GB) 1866/9

Samsung EVO 840 250GB SSD

SeaSonic SS-760XP2 80Plat PSU

Corsair Carbide Series Air 540

I'm running Prime95 on the PC. My question pertains to CorsairLink and Ai Suite 3 giving me conflicting core temps during the Prime95 stress test. I'm showing ~93c on CorsairLink and ~81c on Ai Suite 3.

Is anyone aware of which is actually more accurate? Just curious so I know how much more headroom I have for my OC. The CPU is currently running flawlessly at 4.4Ghz @ 1.25V. Ambient temperature is 22.7c at the moment. Any advice or help would be appreciated. Thanks!

[Lays]

Corsair link doesn't get along well with other monitoring softwares, uninstall one of them and re-test, that'll be accurate.

[HerpinTheDerp]

Thanks! Running the test again without CorsairLink. I appreciate the help.

I would suggest that you basically ignore Asus's AI Suite. It is horrid, it says that my cpu is running at 45 degree's celcius when I'm giving it 1.3 volts. LIKE HELL IT'S RUNNING THAT COOL, I use real temp for my monitoring cause it's actually correct.

[HerpinTheDerp]

Well I ran the test again for about 20 minutes and I maintained ~82c via CoreTemp and 59c via VRM on Ai Suite 3. I'm not completely sure if Ai Suite 3 is accurate or so I'm going to attempt to run Prime95 again with RealTemp. I'll keep you posted. I'll be running 4.6Ghz @ 1.28v this time. Ambient temp is down to 21c. Wish me luck!

Ai Suite 3 is incorrect in temperature monitoring.

[arielfall]

Ai Suite is probably using the package or CPUTIN instead of the actual core temperature.

 

I get upper 50s core temps in HWmonitor vs 60-63 in AS3.

[HerpinTheDerp]

Alrighty. Disregarding Ai Suite 3 at this point. Began my testing with Prime95 again. Ambient temperature is at 21c. The i5 4690k is at 4.5Ghz @ 1.29v. Temps are at ~95c between all cores... sometimes bouncing very close to 97c. I guess it's not too bad of an i5 4690k eh? Thoughts?

 

EDIT: Temps are being monitored via RealTemp now.

Seems quite high, fans mounted in push?

 

The pump fan header is setup for 100% right or is the pump SATA powered?

[HerpinTheDerp]

Yeah it does seem quite high.. rad fans are mounted in pull actually.

I'm not even sure where to adjust the pump settings on the H100i. CorsairLink is very vague honestly. I am probably just missing it. The pump is SATA powered, that is correct.

EDIT: If it's any consolation, the tests haven't posted any errors. I haven't encountered any BSOD either. I'm wondering if I can play with the voltage some while maintaining 4.5Ghz?

Well, if anyone cares.. been playing with the numbers and what not.. got the i5 4690k to 4.6Ghz @ 1.215v. VRM is at 56c... how much lower can I go with voltage before I begin running into issues or any sort of throttle?

EDIT: Ambient temp is 21c. CoreTemp is ~85c between all cores.

[Faceman]

Those temperatures are incredibly high.  I have two guesses, the H100i is not mounted correctly, and my other guess is that you didn't set your voltage to manual/constant before stress testing and it is causing excessive voltage and heat, which is very dangerous.  Before stress testing with any program, set voltage to manual/constant.

 

85C is the absolute maximum you should let temperatures go while stress testing.  Another program I recommend you use is HWinfo, its my favorite and provides the most accurate information for every aspect of your PC in my opinion.

[HerpinTheDerp]

Yeah they're high. Not sure how the H100i could have been mounted wrong...? Would changing the thermal paste have any effect?

 

I've changed the voltages to manual. Not sure what else I could do. Maybe I'll have to settle for less? lol

Retry the tests now that your voltage is set to manual.  You only need to set it to manual when stress testing, when you are not stress testing, adaptive is fine.  Adaptive is bad when stress testing because your computer is being pushed 100%, and adaptive will often ramp up voltages far higher than is necessary.

 

I don't own a H100i, but I hear that the mounting device is difficult to get seated properly with correct pressure, sometimes people have to ghetto rig the back mounting bracket with washers or something in order to get it even.  This might not be the case with your H100i, just thought I would mention it because it seems like a common occurrence with the H100i.

[arielfall]

Put your fans in push and retest.

[HerpinTheDerp]

Aye I appreciate it. I checked the H100i and it looks as if it's on correctly. I ran the test again via Prime95. I pushed the i5 4690k to 4.5Ghz @ 1.215v and was stable with 80c. I'm just confused why Prime95 is running so hot. I ran Intel XTU and it was ~25c cooler. I may have missed an manual voltage setting when running Prime95? Pretty sure I set all voltages manually via BIOS.

     Setting voltages manually and having the voltage be manual are two different things.  Prime95 is known for very high temperatures and is considered one of the toughest tests because of this unrealistic amount of heat.  Set the voltage to manual means that it is at a constant 1.215v even though you aren't doing anything demanding.  You probably still have your voltage set to adaptive, which adapts to what is required of the processor.  When the processor is being utilized at 100% and adaptive voltage is used the voltage will often go higher than what you set it to, this is why you need to set the voltage to manual/constant before stress testing.

 

     Good, you have an Asus motherboard, I can help you much easier.  Go into Asus AI Suite III, go to TurboEVO and change voltage from adaptive to manual.

[HerpinTheDerp]

Correct. I understand that.

 

Looking at Ai Suite III, there's no TurboEVO for the latest version released with the Z97 Chipset.. I assume it's called TPU now? Either way, voltages are on Manual in TPU(New TurboEVO?), and have been since I began my tests. None are set to Adaptive.

 

EDIT: Typing is hard.

[turbobooster]

now way that the temps should be that high.

not with that vcore, even a 4670k with more vcore wil get those temps with a h100i.

so check again if you mounted the h100i correct, just take it of again and reinstall it.

Putting on different thermal paste normally wont, give you better temps that much, the thermal paste of corsair is oke.

but if you reinstall it then you have to put on different paste.

[HerpinTheDerp]

Yeah I'll break down the H100i and reinstall it. It's gotta be the culprit. /sigh

So I searched for some answers as to why Prime95 was completely destroying my i5 4690k. Turns out a lot of people haven't been using it due to it hijacking voltages and what not. Anyone else here has a theory or answer to that conclusion? I decided to run with Intel XTU and Aida64. I'm using HWMontior to monitor temps/voltage/etc. These have been my results this far today.. please note these are readings from Aida64/Intel XTU under load. Fan RPM is set to 100%.

 

Voltage/Multipliers:

CPU Multiplier: x46

North Bridge Clock: 4500Mhz

CPU Core Voltage: ~1.209v

CPU VRM: ~1.920v

CPU Cache/LLC/Ring: ~1.224v

 

Voltages remain +/-0.010 between the list above.

 

Temps:

CPU: 59c (+/-.5c)

VRM: 55c

MB: 26c

 

No BSOD, no issues, no crazy voltage spikes/temps or anything out of the ordinary.. seems to be chugging along quite nicely atm.

 

Anywho, just wanted to update this. I've been running tests all.. freakin... night.. let me know what you guys and gals think!

I just had a similar issue where running a stress test in prime95 at stock everything and was hitting 65c on all cores according to real temp. Is that normal to hit those temps? I've searched and no one runes them at stock speeds and records their temps there so I had to ask.
