I've just finished building a new PC with a CIT Raider case. It comes with 4x120mm RGB fans (3 front and 1 back) with a BOX which is magnetically attached to the case. The fans plug directly into it and its provided power from the PSU through a SATA cable, and controlled by a remote which comes with it. There is also a cable to connect the box directly to the motherboard to control the RGB functionality, but on my Asus Prime B450MA2 motherboard its the wrong plug and isn't really needed anyway. The remote allows you to control the RGB through hundreds of variations, turn the RGB on and off, select fan speed high/low or off. The problem I'm having is there appears to be a lot of these signals floating about causing the fans to change colour, switch off the RGB. I've been sat next to it and the fans just power down completely occasionally. It seems that my Logitech wireless mouse also works on the same frequency (Bluetooth?) and this also adjusts the pattern on the fans. Moving my mouse RF adapter from the top case USB to the rear seems to have helped a bit, but something is still affecting it. I've tried removing the battery from the remote, but its still coming from elsewhere too. I've also read that USB3 can cause this, and my new board having USB 3.1 wondered if that could be an issue too? Is there a way to prevent this happening, and has anyone else had this issue?
Bluetooth, WiFi, you name it, it's probably an RF signal. If you wanted to test it out, you could build a little faraday cage around the control box. You'd obviously lose the ability to use the remote though. You could also sack the fan hub off and just plug them all into your motherboard.
