Hi there, everyone.
 
I've searched quite a bit on google and these forums have shown up quite often but I can't seem to get the flow control software to show my fan speed nor can I get flow control to adjust my fan speed.  I'm guessing that since it doesn't show the fan speed that's probably why it won't adjust the fan speed.  The flow control program does however show the pump speed and I can adjust that.  I have an asrock z370 killer sli/ac motherboard and the 3 pin fan wire connector is currently plugged into the cpu fan connector.  I've tried unplugging/plugging it back in, uninstalling/reinstalling the software but still doesn't show/adjust fan speed  I've tried changing the fan speed through my bios but that hasn't worked either.  Do I need to change where that 3 pin connector is plugged in (possibly the chassis fan connector or optional water pump fan)?  This seems to be quite an issue for a lot of folks and I apologize in advance if there is an answer already posted in these forums. 
 
Side note;  What is a good pump speed?  Mine is set to 2400 rpm but I have no clue as to whether that is warranted or not.  I've tried clicking the auto button in the bottom right of the UI but that doesn't seem to change it all and only seems to respond to manual settings.
 
Thank you in advance!  I feel like I'm going to be hearing this fan noise in my dreams tonight lol  

Thank you for the response!  I have the clc 280 mm (dual fans) and both fans are plugged in. I don't believe the asetek CCVI driver was installed during the flow control installation, never remember seeing that pop up.  Is that a separate download?
 
Edit: I do have the CCVI driver and it says its working properly in device manager.

Yup that is showing up in the device manager and it says that it is working properly and I have the latest drivers for it.  The usb 2.0 header is also plugged in.
 
Edit: If it helps any, I can't move the nodes when I hit the curve button in the flow control UI.  No matter which box is picked, the nodes are gray and are immovable.

Gotcha, I think I might have to send EVGA an email or give them a call.  I unplugged/plugged everything back in, uninstalled and reinstalled the program 3 or 4 times now so I'm not sure if there's anything else I can do.  Even tried playing around in my BIOS messing with fan control but it didn't seem to do anything. It shows the RPM there for the fans but not much else.  Thanks again for trying though, much appreciated!

Glad to see you got it :)

I have the same issue.   My fan is not coming on at all.  CPU temps are climbing.
I have the 1FAN CPU cooler.   It was working but for some reason it is not coming on and there is no fan speed showing in my control panel.
 
 I had the motherboard seat to no fan profiles.   The fan is plugged into the fan AIO connector.   I also plugged the other connector into the pump connector.
 
Can anyone help save my CPU?   This is far too complicated just to get a CPU cool.
