FREE GAME FOR SOLUTION! CPU running hotter than it should

[Leonardo1364]

OK.  Quick bit of info.  I have an i7-4790k at stock speeds, and an Nvidia GTX Titan X together in a custom water loop.  I have an 80mm thick dual 140 in the front of my case, and a 30mm thick triple 120 in the top.  All using Aerocool DS fans.  Which have proven to be amazing by the way.  All of this inside of an NZXT H440 case.  I have one pump Swiftech MCP50x which does the job very well.  I never have flow issues at all, as I can visibly see water moving very well even at low RMP.

 

Now, my issue is, when playing games like COD Black Ops III, or encoding video files for my server, the CPU pegs over 75c.  I am perfectly fine with this temp, though I feel with the amount of cooling I have, that is quite high.  The issue is my motherboard (Asus Sabertooth Mark 1) revs the pump up to 100% automatically once CPU passes 75c.  And this then makes the computer loud.  I paid for quiet, not loud.

 

Does anybody have any ideas why this would be happening?  I have adjusted my CPU block a couple of times, so that shouldn't be it.  I am using the best thermal paste there is without going to the liquid metal stuff.  My idle temps run great, anywhere from 28c-32c depending on ambient temperatures.  It seems I am doing everything right that I can think of, but still getting temps above 75c which to me isn't OK when the CPU is at stock with that kind of cooling.

 

So, does anybody have any tips on how I can keep it below that 75c mark?  (the max it ever gets is 78c ironically enough)  That, or an option that allows me to keep the CPU fan running at about 30% speed at all times no matter the CPU temp?  I have attempted plugging the fan in elsewhere, but the board won't allow bootup without a CPU fan.  So I would HAVE to have a fan then that is going to ramp up to max speed constantly, which would defeat the purpose of moving the pump elsewhere.

 

Here are my specs in case it helps.

Also, whomever can come up with a functional solution that is not going to cost me a fortune, or involve turning my A/C down to like 60F will receive a copy of

 

ARK: Survival evolved for free....

 

Just sayin.

How close is your GPU in relation to your CPU. Also have you cleared any dust that might be in your PC out.

I have a feeling that one of your rads might have a defect

[Leonardo1364]

GPU is in top slot of the motherboard, and dust is filtered at intakes, and blown out 1-2 per month (though next to none when it is blown out)

Solution probably lies in the BIOS. Go and change fan curve for the CPU fan and adjust it to your liking noise wise. That should do the job. Also you probably can set the board to ignore the "missing" CPU fan if you plug the pump on a different header. Linus did thin in his personal rig.

Though lots of things that Linus does break things.

If water flow is consistant, and airflow is able to be felt throughout when all airflow is run through rads, I don't know if that would be the case....  Even at very low fan RPM, airflow is very good through the radiators.  Same with the Water Flow.

Fan curve in BIOS is set properly, but as stated, once the 75c mark is hit, the fan curve automatically goes to 100%.  Cannot be altered for the CPU fan.  It can on other fans, just no the CPU one.

 

I currently keep the CPU fan at 30% (the water pump) and the rest of the fans at 50%.  The Water pump does not effect temps running at 30% vs 100%.  I have tested both.

That is true. That's why I put it as a second option. It would be much better if the firs solution did the trick.

[UltraNeonGaming]

Hmm that's weird, have you checked the voltage being supplied to your CPU? I would reset your BIOS to factory settings and see if that helps.

 

Also your fans run at 100% when the CPU hits 75c because that's a thing in AI Suite, you can turn that off in fan xpert. You should also play around with your fan xpert settings in AI suite, you'll be able to find the solution to your fan and pump RPM problems there.

Another thing to try is to have your exhaust fans on top I've found this to help since heat rises. And you should probably have 4 intakes and 2 exhaust as your intakes are what really helps cool it especially when they're near what your trying to cool.

Why didn't I think of that. Yes. Do that

I have intakes in every slot except the triple 120mm rad in the top of the case.  The only way I could have more intake is to change one of the top fans to an intake, which will screw with the airflow hurting me more than helping.  Plus, the 140mm fans obviously move more air leaving my case with a positive air pressure at all times.

 

Also remember that these are liquid cooled, so air does not flow over the actual CPU or GPU much.  It is very minimal, even when high airflow is in the case.  It is the airflow over/through the radiators that is making the difference.

I got Ark, but try to reset the CMOS if no good try to boot another drive with fresh Windows or Linux and see if it still happen...

I have cleared CMOS previously, and still has the issue.  I also do a fresh install of windows every month or two to ensure no viruses or malware stick.

 

On resetting the BIOS/Clearing the CMOS.  That sucked.  I didn't reset my BIOS to RAID before booting into my OS, and it broke my RAID.  Had to re download all 600+ games on my Steam, Origin, Battle.net, and Uplay.  That was miserable......

Are you using Windows 10? If so I am out of ideas except trying a better cooler...

This would be the best solution so far, bar none.  But I can't see where to turn off the 75c cap in fan xpert.  At least for the CPU fan.  For all other fan headers, you can turn it off, which I have to keep my fans running at 50% no matter the temp.  Best performance/sound ratio I have found.

When you're running Bo3 is your CPU under full load? Also, when you applied your thermal paste you didn't use to little did you?

Yes on windows 10.  You think switching to the EK supremacy would make a difference?  The Apogee XL is supposed to be right up there as one of the best.  I wonder if it is not working properly though?  Maybe that is the issue?

[Chronical93]

Also how long have you had your water cooling unit your pump may be slowing down causing the overheating.

[Ben_Upde]

I was having similar issues with my setup and found that using the upper fans as exhaust fans actually heated my rad up from the warm air from the GPU. My fix was to pull air in through the top and force it to exhaust out the bottom. Since my MB is inverted this also added the benefit of more air forced onto my GPUs allowing them to run cooler.

Okay now I am quite sure that is the problem... Try to boot ANYTHING else than Windows 10! (some PCs cannot handle Windows 10 and /or need a re-install)

I did not use too little.  And apparently, based on a recent video Luke did, it doesn't really matter anyways....  Ha ha.

Well, in the video the only wrong method was using too little if you remember. But yeah I doubted you used too little just had to ask.
