Hey guys, first post here however I have been a forum lurker for quite a while. I just recently completed my PC build this past weekend and got it up and running finally due to time constraints.

Anyway, I'm currently running a full prime-95 stress test and am getting some pretty un-real numbers.. The test has been running for about 45mins now, and at full load my temps for the CPU bounce between 35-36 degrees C!! This seems like extremely low and unrealistic temps.. I also ran a 15min test in Aida 64 and my CPU didn't go above 36 there as well.. Have I not configured something right lol? At idle, the CPU is right around 28 degrees and this is all on a stock clocked 4690k.

System specs:
I5 3690k (all stock clocks and voltage)
ASUS Hero VII mobo
GSkill ripjaws X 1600 ram
Corsair H100i
ASUS gtx780
Corsair HX750 PSU
Corsair 500r case

..I would attach a pic however I'm on my phone and want to let the PC continue the test before I start surfing the web..

This is not a troll post or for attention, truly looking to see if these temps are as outrageous as I'm taking them to be, and seeing if I have configured prime wrong..

Something is wrong there, even having a h100i, haswell and devils canyon are very hot cpus.
But it can all be ok and you have the best chip of the world haha
Still maybe the temperature sensor can be faulty!
Can you also run OCCT cpu test?

I figure something isn't configured right or like you said, the integrated temp sensor is faulty.. However it does read and scale temp when load is applied. I ran a full prime 95 stress test for a little over 2 hours last night and the CPU didn't see anything over 42 degrees the whole time..
All cores were stressed and reading 39xxmhz. I also took out my Laser Fluke temp gun and the side of the socket was reading 34.. Something isn't right here guys.

IMO i think you won the silicon lottery as someone said above haha
If the cpu temps scale when at load, it shouldnt be a faulty sensor!
You are running with h100i max speed during prime 95? if yes probably its all fine, you got lucky with that chip

well ryan, devils cannon supose to have an improovement between 8 and 18 ºC vs the past thermal solution gen.

but even so, you must be in canada or something... or a very cold place, otherwise the temp sensor could be defective .


sooo check the temps in CPID hw monitor or AIDA you will see that they also has the messure of each core, thats the good one cose sometimes there is a huge difference between the temps of cores and CPU

EDIT:

since the temps are so low you can always try to touch directly with your fingers the CPU but be careful... if you were using an air heatsink it would be much easier...

The fans on the radiator were running at 100%, the actual pump/waterblock is a static speed getting power from a SATA connection, there is no feedback telling the pump to ramp up/down so i assume it is static.




I'm actually in California so no, it isn't cold haha, I live about 5 minutes from the Silicon valley as well. I had AIDA as well as the ASUS monitoring programs up the whole time which is where I got these numbers from.. I will install HW monitor tomorrow and test again (birthday is today, no time).

...Im thinking about just adjusting the CPU voltage a little bit and seeing if the temps rise accordingly.. Thoughts?

Yes you could try that with the voltage. Also all 4 cores are being used right?

Yes sir, all cores are reading ~3900mhz.. Can I not attach a photo on these forums?

What do you mean by can i not attach haha? you can
Try increasing voltage as you said, but low increases, and then run prime95 to see if the temps increase or not :)

Yeah, other tan upping the Volts im not too sure how exactly to diagnose this problem.. Will report back. If these temps are indeed the true reading, you will be seeing a hell of an overclock tutorial thread posted up here in the next week haha!

Hahaha, i believe you, with those temps i think you could even sell that CPU for more money that you bought it (just kidding, still i dont know haha)
Ok write the temps you got after increasing the voltage :)

well Congrats then!!

if you rise the voltages the diode will sence a higher temps... since it sences now. what i'm trying to say is for example i have a phenom II with OC and i thought the temps whre ok since the sensor never passes the 60ºC... but when i looked at the core temps they where above 65ºC all of theme... while playing (then i just set voltajes and clock a little bit lower), the diode is actually defective but works "fine"

so i might think the diode of your chip could sence a little lower... if your laser sensor also sence lower temps theres no need to touch the chip

i think you have what some folks call a "binned chip"... a chip with better silicom than others that can work with lower voltajes and lower temps i think your i5 was mant to be an i7
so try it with lower voltajes as well if it still stable you are a very lukcy guy

Exactly.. These calibrations will only be applied to my system fo the duration of a stress test to see if indeed my cpu is "Binned" or not.

UPDATE**

Turns out the readings I was getting from the Motherboard were false.. I figured it seemed far too good to be true lol.

I've been running Prime95 now for a little over an hour, and the hottest temp I have seen is 61 degrees.. With it averagely sitting around 48-51. How would you guys rate those temps for a stock clocked i5 4690k?

How do you get those readings??
also the 61º, are they core temps? and is turbo clock enable?
i think are high for a H100 with fans woking at 100%
