Hey guys. I just bought an EVGA Z390 dark mb with a 9900ks cpu. I also paired it with a Corsair 150i AIO water cooler. Yesterday I decided to stress test it with Real Bench. CPU was set to hit 5.0ghz all cores (which is stock) with auto VCore. Ran the test for 30min. The test passed but temps were hitting over 100 degrees. I was wondering if this was normal for these CPUs? Or is there something wrong with my cooling? Any advice

    Hello and Welcome to the Forum 
     
    We need to know what is your FULL spec of your PC and What OS Windows are you using!
    That definitely not accept over 100c temp! It Tjunction MAX 100c  
    What is the voltage reading in your BIOS setting for CPU which is left Auto it will reach high voltages! May need change to manual voltage? 
    Did you use thermal pasta for your CPU? Checking your cooler pump seat firm properly?

    Be sure you have the latest BIOS available for your board in the EVGA Download Center.
     
    You need to see what the Vcore is under load using CPU-Z or similar utility.
     
     
    And check you cooler mounting.

    How come hit 100c for 1.2 voltage??? Thanks for your Full spec and put on in your MOD RIG
    Have you check your CPU Water Cooler AIO pump?
    EDIT> Have you update your BIOS what Bob send you link above?

    +1... yeah this sounds like its a temp bug with a outdated bios or the utility you were using maybe. What gpu? Were you benching the gpu too?

    I would double check your thermal paste application and make sure the CPU is properly mounted to the CPU socket and applying the full pressure. I had a i9 9900KS for a day or so and ran a bunch of tests on it for about a 4-5 hour run... It got pretty hot under my custom loop... 75C was the max temps I saw and it would only be for a moment before it would drop back into the 60C range.

    Run CPU-Z while testing to monitor your CPU
     
    Auto voltage is known on All MB to allow more voltage than is probably needed
     
    So if your cooler is mounted & working as designed .. I'd manually set the BIOS to control voltage

    The 9900ks is generally a hot running CPU so don't expect it to ever run cool with an AIO, that said 100C is way to hot. It appears you have a decent AIO cooler so make sure you are on a updated bios and try re-pasting the cooler.

    Yes, those CPUs do inherently run on the hot side, but shouldn't get that hot at stock settings.
     
    Also be sure the fan header that you connect the pump to set to 100% manual speed in the BIOS, not Smart Mode..I thought there may be an AIO_PUMP header on that board but I'm not seeing one.

    Now thinking about it, when I was messing around with my AIO on my 2nd PC I ran into 100C temps on my processor, it took a few minutes for it to get that hot... but I found out that when I put the side panel back on, it somehow disconnected the SATA power that goes to the pump... Once I corrected the problem, my temps were back down to the low 30's almost immediately. As Bob mentioned, make sure the pump is working. You should be able to feel a slight vibration on the CPU block.

    The AIO might be not enough for this CPU under prolonged stress. If the AIO wouldn't work at all, as some have stated, your PC would meltdown .

    finally a signature without that associate code

    I use the Corsair H150i Pro 360 mm AIO on my 9900k and it does a decent job for me. My cores certainly do not get that hot, usually in upper 60's low 70's.
    Running 5.2 GHz on all cores with voltage set to override at 1.318v and -75% vdroop.
     
    I would take a good look at re-seating that cooler. Definitely stay away from auto voltage, I would not even use adaptive, use override.

    The Dark really, really, overvolts on Auto.
     
    Without knowing the load voltage, hard to say if that is the problem or not.

    While I do not own a 9900K, from general reading since release, they do seem to run HOT, but not nearly THAT HOT. Sounds like your voltage is way to high, or it's very possible your AIO has some air pockets in there. I had fought with a Corsair H80 a while back where somehow some air found itself in the CPU block and refused to leave. The CPU temps would spike and system would shutdown. The pump & fan both showed normal operation, so I knew something strange was going on. Upon inverting the chassis of this computer, you could hear air start moving through the radiator & tubing, and CPU temps dropped to normal levels almost instantly and stayed that way. CPU temps were about 20-30C high, and that was on a old Phenom II X4 965 system(still chugging along).

    Re: CPU temps help 2019/12/12 18:20:10 (permalink)
     I have the SAME exact problem with my 9900k, to get the cpu to run at stock I have to set everything to auto, then, on the cpu "OC" tab/page, change the voltage to "override" at a target of 1.198v and -75% vdroop, to get it to run LinX and keep the temps under 80c under extreme full loads.
     
    Also, try to use CPUID HWMonitor to keep an eye on everything.
     
     I can run this 24/7 and it runs perfect. But you can try higher voltage "override" with a target of "up to" about 1.25v with the 75% vdroop and see how it does.
     
    good luck. 
     
    OH ONE MORE THING, for running the cpu at stock (or as close as your going to get..lol) if you run the "Extreme Power Profile" in windows 10 pro, you need to set the minimum cpu setting to like 95% IN that profile, it will let it clock down to about 3200 when the cpu is not being used, OR you can just use the balanced profile. However, IF you are going to "overclock" use the Extreme Power Profile and set all CPU setting to 100%.

    Re: CPU temps help 2019/12/12 19:45:05 (permalink)
    ok guys so I found a couple of things. Number one was I was running a push/pull config but I probably ran the fans the wrong way. Removed the fans. Second I noticed that the 150i pro was plugged into the AUX port and not the CPU_FAN port as stated in the manual. 3rd I noticed that one of the fins from my rad is bent pretty badly. Just ran a stress test for 15 min at 100% cpu work load at 5.0ghz at 1.2volts. Max temp hit was 84 degrees with it roughly jumping around in the 70s. Not sure if this is normal or bad. Also how much impact will the bent fan from the rad have on cooling?

    The CPU cooler fans should be oriented so that they're sucking in outside air.
     
    You should be running the fans (including case fans) and pump at full speed with Corsair Link (in Downloads) when stress testing/benchmarking.
     
    Just straighten out the radiator fin as best you can, no biggie.
     
    But i'm calling the core temps in normal range now for that CPU/Cooler, but some BIOS (make sure you have the latest version) CPU Voltage/Vdroop (LLC) tweaking might get them down some..RealBench is pretty stressful..I'm seeing pretty much identical core temps as you (81C max) and that's with my 8700K OC'd to 5.2GHz, delidded and using Thermal Grizzly Conductonaut TIM.

    What is the newest bios version for the z390 dark? Is it 1.07 September release? Also would upgrading the fans say from 47cfm 1400rpm stock fans to 75cfm 2000rpm fans make any difference in cooling? Would I see lower temps?

    1. Yeah, 1.07 is the latest
    2. Maybe a little, probably not much, I dunno
     
    Like I said, you might be able to get the Vcore/Temps down more by manually adjusting the CPU Core Voltage and Vdroop.
     
    Try running the Intel Processor Diagnostic Tool, or IntelBurnTest for for a quick and dirty stability test for the CPU..There's Unigine Superposition for a good gaming benchmark.

    'Also would upgrading the fans'
    it will not much different really but I did change my silent fans on my EVGA CPU Cooler radiator from EVGA fans are more loud noise!!
    For your EVGA Z390 Dark motherboard there some fans pins! I recommend to put Cooler Pump on to PWR FAN on motherboard and those three spilt fans pin for radiator you can connect from your CPU cooler! The Cooler pump must need full speed and the cooler fans for radiator you can adjust speed in Corsair Link what bob said!

    Always make sure you tighten down your retention bracket in an X pattern (top left, lower right, top right, lower left) to get the best contact on the CPU lid.
     
    After that check voltages and as you already stated, where things are plugged in to headers on the board.

    ok guys so I found a couple of things. Number one was I was running a push/pull config but I probably ran the fans the wrong way. Removed the fans. Second I noticed that the 150i pro was plugged into the AUX port and not the CPU_FAN port as stated in the manual. 3rd I noticed that one of the fins from my rad is bent pretty badly. Just ran a stress test for 15 min at 100% cpu work load at 5.0ghz at 1.2volts. Max temp hit was 84 degrees with it roughly jumping around in the 70s. Not sure if this is normal or bad. Also how much impact will the bent fan from the rad have on cooling?



    Ambient temps can have a significant effect on water cooling temps as well.
     
    And, you did not say which stress test you ran (RealBench?), obviously some are more stressful than others.
     
    Also, what AVX offset? VCCSA and VCCIO voltages may add to temps.

    Yes Realbench. No AVX offset and no vccio or vccsa voltages (auto)

    My Dark sets the voltages too high on Auto, I would suggest using Adaptive or Override to manually set VCore, Vccsa, Vccio.
     
    You did not mention what your ambient temps are.

    I found adaptive to get crazy eventually also, override gives me the best consistency so far.

    Re: CPU temps help 2019/12/17 16:49:38 (permalink)
    So I managed the following settings after stability tests:

    5.2ghz @ 1.32 volts
    AVX offset - 2
    Vccio - 1.15
    Vccsa - 1.15
    4000mhz ddr4 19-19-35

    The temps are still crazy high at 100% load. Aka around low to high 90s. I find that 9900k is affected by voltage big time. I was able boot up 5.2ghz at 1.21 volts but only lasted about 5 min of stress test. But the temps were in the 60s. My 7700k wasn’t affected by voltage as much. Gaming temps are around 60s to 70s. I’m pretty happy with the results. Would an ek custom loop lower temps any more compared to my Corsair 150i pro? Worth the upgrade?
