Is my CPU temperature accurate?

[djkim0403]

So I've been overclocking my i7-6800k and the temperatures are far lower than any reviews I've seen...anyone else getting these temps? Is something broken? I've heard that if the temperature readings are too low, the socket or something could be broken, but I'm not sure.

 

My rig:

Case - Rosewill THOR V2

Mobo - MSI Extreme Gaming X99A SLI Plus

CPU - i7-6800k

CPU Cooler - Noctua NH-U14s with Arctic Silver 5 thermal paste

GPU - EVGA GTX 1080 SC

RAM - Corsair Vengeance LPX 16 GB DDR4 3200 mhz

Storage - 512 GB Samsung 850 Pro SSD

PSU - EVGA Supernova 850 G2

 

***Temp Tests***

I performed load tests using AIDA64 (14 hours) and ROG RealBench (3 hours). I also used Prime 95 but I heard newer versions could damage the computer so I didn't do it very long; temps were similar though

 

Ambient Temps are around 17-19 degrees (I like my apartment a bit colder)

 

Temps without any overclock:

Idle CPU - ~20 degrees; GPU - ~29 degrees

Load CPU - ~51 degrees; GPU - ~67 degrees

 

Temps with CPU overlocked from 3.4 Ghz to 4.2 Ghz and core voltage at 1.290 V

Load CPU - hovered around mid-60 degrees, peaking for moments at low 70 degrees; GPU - ~67 degrees

 

I play Battlefield 1, maxed out all settings on 1440p monitor, and CPU temps don't go higher than mid-50s

**********************

 

I used AIDA64 and CPUID HWMonitor for temp monitoring

I didn't take a lot of screen shots, but here is one of them.

 

All the reviews I've seen are up in the 80 degrees...

Are my temperatures accurate?

nope its normal its a good thing it means your computer is properly cooled.

No such thing at too cold. Unless it's actually frozen to the point it won't work. But no one will have to worry about that. Unless you use liquid nitrogen then maybe you do

no such thing as to cold

You need to go into AIDA64 preferences and enable Package Temps.  Pay more attention to Package Temps than core temps on a Broadwell-E CPU.  

 

Also, when you run AIDA64 for CPU stability, only run CPU, FPU and cache checked otherwise your temps will be a little lower when you run all tests like you did.

 

Other than that, your temps are average for your overclock.  Nothing to worry about.

 

As an example of why you should monitor Package Temps, look at the screen shot I've provided.  You'll see all of the core temps in the 50's, but package temps (Purple Line) are much higher.  Haswell-E and Broadwell-E package temps get quite a bit higher than core temps.  This is only to show you the difference in Package and core temps, not for comparing temps as we have different hardware and overclocks.

@done12many2 - Thank you, this was very informative and helpful! I'll test it again just to make sure!

You're welcome.  

 

I should have explained why it's important to monitor Package Temps.  On our chips, the Fully Integrated Voltage Regulator is actually on the CPU as opposed to smaller Intel CPUs.  This allows better CPU voltage regulation, but unfortunately results in higher overall CPU temps.  Our cores can run cool, but the overall CPU temps are higher.

 

With regards to Prime95, it's not so much the temps that you have to worry about, but CPU power draw.  Prime95 is still great for testing stability on Haswell-E and Broadwell-E chips, but you have to be mindful of doing so while at a higher clock speeds due to the amount of power the chip draws under this type of load.  Too much juice through the chip can lead to issues.

 

Good luck in your overclock!
