If your MSI case fans are not working properly, there are a few things you can do to try and fix the issue. MSI Afterburner is the most widely used overclocking software for graphics cards. To access the PCB fan connector, drill a 13mm bit through the acetyl cover. Any MSI 1080 card that uses the same PCB or MSI 1070 that fits the same waterblock should be able to run this hack.

If you attempt this on your own, I assume no responsibility for the consequences, as well as your computer or world. If you have plenty of rad space, or if Speedfan works well with your motherboard, you do not need to install it. You can also set a custom fan speed profile for your case fans, which will be activated when the graphics card is under load.

There is a dedicated fan control tab in Afterburner, which allows you to set the fan speed curve for your graphics card. Afterburner is a utility program that allows you to control the fan speed of your graphics card, as well as overclock the GPU and memory. The short answer is yes, you can control case fans with MSI Afterburner.
