I have a CLC 280 on Gigabyte Z390 motherboard (Aurus Z390 Master), Flow Control does not show or control FAN speed, where it should show fan speed it is just blank.
 
The fans are running but not very fast, and as soon as I ask the CPU to do work it heats up and eventually crashes after it reaches 100 degrees.
 
I have double checked connections, I reinstalled software, nothing works.PLEASE ADVISE....

    Which motherboard header is the fan hooked into? My guess is the motherboard is controlling the fan on the header that it’s plugged into. Normally that can be changed in the bios so that it runs at full speed. The software will allow control but needs the bios to give it full power.

    Well, as instructed in the manual (which leaves a lot to be desired it has to be said) the fans are connected to the Y cables that says TO FANS, and the 3 pin cable labelled TO MOTHERBOARD was connected to the SYS FAN6 PUMP connector.
     
    I tried that TO MOTHERBOARD cable in the 4 pin CPU FAN, and still the FLOW CONTROL software does not control the fans, nor does it see the fan speed.

    OK fixed it.....with it connected to the SYS CPU it still does not register fan speed or control UNTIL you set the fan to FULL SPEED in the Gigabyte SIV app.

    I am however wondering why the PUMP is now running at 2900rpm all the time? Is this normal or is that way too high considering the CPU is 33 degrees?
     
    I do not think this is right, if I do a video render the CPU goes straight up to 85-90 degrees (and higher) the fans do not increase speed as the coolant is staying at around 35 degrees, which I am guessing is because the water is flowing to fast to draw the heat out of the CPU?? Surely it should control flow automatically, but it does not seem to be doing so. If I manually adjust it will only slow to1 1950.

    OK this is not resolved at all.....I now get a message popup when I try to launch flow control: CPUWB Device Not Found...which means what?

    I can not reply to your PM as your system will not let me, something about not being a member long enough??

    "Can you give me some information on this set up. Do you have any of your radiator fans installed to the motherboard or the Y-spliter?"
     
    The radiator fans are connected to the Y Splitter.
     
    "Also do you have the 3 pic CPU header installed to CPU1 header on your motherboard?"
     
    The 3 Pin CPU Header is connected to CPU FAN, but....I just read that the CPU OPT is for Water Cooling CPU Fan Header, so I shall try that now and report back.

    OK switched to the CPU OPT for the TO MOTHERBOARD cable. Now when I open the Flow Control app it looks different for some reason, the interface I mean. Anyway, same problem, the water pump is running at 1950, does not seem to automatically adjust.

    I also ran the AURUS Smart Fan Calibration on the pump, it slowly wound down the pump speed and fan speed during the calibration, and now they both sit a ZERO and do not come on at all.....

    Yes, the manual leaves some to be desired.
     
    I would connect the 3-pin pump connector to the SYS_FAN5_PUMP or SYS_FAN6_PUMP headers (System Fan/Water Cooling Pump Headers).
     
    Then I would clear CMOS (Page 39 in your mobo manual) because some software/utilities will change BIOS settings/Fan header/Smart Fan settings..Things may be all messed up now.
     
    After you clear CMOS it might be a good idea to reinstall, or uninstall and reinstall, the EVGA Flow Control Software.
     
    Make sure the Mini USB cable for the pump is connected to a motherboard USB header, which I'm sure you probably did.

    Thank you for this....this is how I originally had it setup and seems to be the most logical path. After trying a number of configurations, even hooking fans directly to motherboard etc, I am now back to this setup. I also did as you suggest and cleared the CMOS, so I am truly back to square one here...
     
    So after booting up, I am also back to having the Flow Control software NOT showing fan speed at all.... To be honest I am totally regretting this purchase. I am ready to send it back and just get a simple air cooler as nothing I have tried with this thing will keep my i9 9900K CPU cool enough.
     
    I do not think it is a good thing for the CPU to sitting at 95 degrees for several minutes while a video rips out etc, it is sitting to close for comfort to that 100 degree mark. THIS is the reason I bought a water cooler, to prevent this, but so far just a world of frustration.

    Also in the BIOS -> M.I.T. section there's a setting for 'Fan/Pump Control Mode'..[Auto] is the default/auto-detect setting..[Voltage] is the mode for 3-wire pumps/fans..[PWM] is the mode for 4-wire pumps/fans..Might try putting it on [Voltage] just for the header that the pump is connected to (SYS_FAN5_PUMP if that's where it is).
     
    And make sure you're using the latest Flow Control Software.

    Re: CLC280 on Gigabyte Z390 motherboard, Flow COntrol does not show or control FAN speed 2018/11/10 18:08:29 (permalink)
    OK...I have it working it seems. The FAN speed shows ZERO until they kick into a higher RPM it seems. To get the pump and fans to really perform however requires setting the Fan Performance on the motherboard to PERFORMANCE or FULL SPEED. Having set it to FULL SPEED, the pump is now running at 2900 RPM constantly, the fans are varying, sitting at 1300 rpm now with water coolant at 31.7 degrees celcius.
     
    It seems to me that the water pump speed SHOULD be varying also, but is not. I can of course control the pump speed a bit with the slider on the left side of FLOW CONTROL, but even on it's lowest setting it is still running at 1920 rpm. So my question now, why is it not be automatically varied?

    To those sending PMs to me, sorry but I am not able to reply as the system will not let me because I am new to the board it seems. But I appreciate your contact.

    So I plugged my CLC 280 fan cord into the 4 pin CPU_FAN spot on the motherboard, then I set the CPU FAN to PWM in BIOS.   HWMonitor shows the CPU_FAN at a constant RPM, however, Flow Control is adjusting the fan speed and reports ranges from 1040 up to the max (I cannot recall off the top of my head).  The only problem I have is when I try to configure custom curve control for both Fan and Pump Curve in Flow Control, the check box will only allow me to do Fan or Pump Curve.  I cannot have a custom curve control for both.  Seems really stupid to me.. but if I check one the other unchecks.    I have a Gigabyte Aorus Z390 Ultra with EVGA CLC 280.

    The problem is the Aorus Ultra. I have a different pump (be quiet)with similar problems. It's not providing proper voltage or PWM information. Even when set properly in the bios. I had to attach the pump directly to my PSU to get it to run full speed and it's only drawing .25 amps so I fear it must be a bios issue.

    Some /(Most ?) AIO pumps Do Not like or support PWM feature.  They rely on the Software to control speed 
     
    With EVGA CLC ---> Make sure the fan header setting in BIOS is set to MAX or 100%. Do not use a PWM fan curve for the header you connect the CLC to.

    Forgive me for raising this thread again, but im having the exact same issue with a CLC 280...
    I cant get it to work with the "Y" cable or even the coolers directly to a header, I have the z390 Aorus Ultra like @
    Anyone found how to make it work ?

    Similar issue. As I have to set the CPU_FAN header to run at 100% in BIOS for the AIO to get enough power that makes my fans spin constantly at 1400RPM in BIOS and HWMonitor but Flow Control reads the fan speed at 1050RPM which isn't correct. I wonder if the Corsair H110i is the same way? first AIO. Really like the CLC 240mm but at 1400RPM it makes a low humming noise. Might have to replace the fans I guess.
