How Do I Troubleshoot Issues with Flow Control For My CLC Cooler?

Last Update: 2019/08/07

If you are experiencing issues with your CLC cooler such as not being able to control LED's or fan speed, there are a few steps to try.

First, make sure that the pump cable is secured to either the CPU or AIO fan header on your motherboard. You will also want to make sure that the respective fan header is set to 100% or MAX power. Many motherboards have an "Adaptive" setting as default. If the header is set to anything other than 100% or MAX power then there is a good chance that the CLC cooler will not have enough power to function properly. The majority of CLC issues can be resolved simply by checking the fan header power setting.

Second, ensure that the USB cable is secured to the pump and a USB 2.0 header on your motherboard. The CLC used a standard Mini-USB connector, which is a common cable for many devices such as cell phones or portable speakers, so you might also want to test with a different cable if you have one available.

Finally, if you are still having issues with the Flow Control software you may need to perform the following:

1) Uninstall Flow Control and any other EVGA software if installed
2) Delete only the "EVGA" folder from "C:\Program Files (x86)"
3) Reboot the system.
4) Ensure that the Visual C++ Runtime Redistributable is installed from the link here: http://www.microsoft.com/en-us/download/details.aspx?id=40784
5) Reinstall Flow Control
