Cooling problem please help.

Primecarter · Aug 2, 2016

CPU is randomly shutting down and im 99% its cause the cpu is over heating
But what can't figure out is why.
My setup is intel i7 4790k
MSI Z97 MB
Case is the NZXT 410 Phantnom
Cooler: Cosair hydro series H100i GTX extreme Performance water/liquid

How do i find out at what temp the computer is shutting down exactly and I bought this cooler because I thought it could handle anything my cpu could put out
I don't know much about overclocking it so I have OC genie from MSI Bios turned on
and I don't put a heavy load on it anyways so I don't know whats going on
If my room is not 75 degrees F* or below the cpu will quickly overheat on simple games like CSGO or League
The case also has 3 fans running 1 in the front 1 in the back and one the side 1400,1400,1500 rpm respectively
Even if I leave my case completely open the cpu will still overheat so I dont understand
Do liquid coolers only work in very cold enviroments I don't understand?

Download RealTemp and check your temperatures. Also Download CPUz to see what clocks/voltages your CPU is running at. once you it these reply with both what voltage your cpu is running at and what temperatures.

OC genie isn't very good and known to add too much voltage into your CPU, which cause high temperatures which can damage your CPU.

Turn OC genie off, and then check temperatures again and post results. Auto overclocking utilities tend to overvolt CPUs which means increased heat.

If turning off overclocking doesn't help, make sure the water block is seated firmly against the CPU. If it is, then you might be experiencing pump failure in your H100i.

pics of the temps and voltage with OC Genie on
I'll be turning it off in a sec

For reference my room is around 75* F right now idk if that factors since I don't believe it should but
if I don't keep it cold the temps would be wayyyy higher I think

Aladdad · Aug 2, 2016

Everything seems fine. but idle temps is not what matters its underload temperatures that matter. Download Prime95 v26.6 from here ( http://windows-downloads-center.blogspot.com/2011/04/prime95-266.html ) and use Small FTT test and see how your temps/voltages are at.

idk what I'm looking at so I'm just following your instructions lol

Your CPU is not overheating. How are your GPU temps? While we're at it, what GPU and what power supply are you running?

Aladdad · Aug 3, 2016

Did you disable the OC Genie before stress testing? seems like your CPU now is running at lower clocks/voltages. temperatures are very good.
you can start overclocking by going into the Overclocking tab in your bios.

Set your CPU ratio to 44 (4.4Ghz) scroll down and set your CPU Core voltage at 1.200v then save your setting and start Prime95 and test using Small FFT and let it run for a bit and see if its stable, check your temperatures too.

If its not stable then increase your voltage by .005 but if its stable you can try increasing your CPU ratio to 45 and keep repeating until you reach a clock speed/ temperatures to your liking.

Try to stay under 1.300v and 80c

Good Luck!

how do I find my gpu temps
and im running a EVGA 970 GTX
and my PSU is EVGA superNOVA 750 Platinum

scuzzycard · Aug 3, 2016

So the power supply is more than adequate. Download and run MSI afterburner or GPU-Z to monitor GPU temp.

Primecarter · Aug 3, 2016

Aladdad :

I did turn off the Genie before stress testing so I want to believe that was the problem
I want to believe that was it but Ive played around with everything so much I feel as tho the comp has shut down before and Genie wasn't running
I will try what youre saying too about playing with the overclocking
thanx for everything so far
I'll comeback to the thread if The computer shuts off again and post results
also is 900 rpm good for the cpu fans to be turning at? because I set all the fans to max speed and thats the max speed they will run at

Primecarter · Aug 3, 2016

scuzzycard :

wait a second.....
my GPU's fans arent running at all is that normal?
I've never noticed it but they are completely off.

please excuse the paint skillz

Aladdad · Aug 3, 2016

Yes 900rpm for the fans that are on the rad? that is pretty much the "Quiet" Options in Corsair link. its fine

you can set it on balanced though so it can increase during load or make your own custom rpm curve in the corsair link application

Yes, EVGA Cards has a Silent feature where the GPU fans will not spin unless the GPU reaches 60c

Primecarter · Aug 3, 2016

Aladdad :

ok just making sure I got scared there for a second.
Also mind you all this is happening with the case completely open
like no sides panels or top panel
I dont think I should have a problem when I close everything thing up esp since I have the 3 fans running right?

Aladdad · Aug 3, 2016

You Should be fine. if anything it would be a maximum of 1-5c increase

Primecarter · Aug 3, 2016

Aladdad :

Alright sweet
Imma close everything up and see what happens
If i run into any problems should I come back to this thread or make a new one?
You've all been really helpful
