I'm new to building PCs and inherited this one from my sister, which has RGB fans that I'm looking to replace. Unfortunately, they don't seem to come with any color customization options, and third-party software hasn't worked for me. I checked out the inside of the case, but I can't figure out where the fan connections are. Here are a few questions I have:
1. I believe I'm looking for the connection point for the fan wires, but I'm having trouble locating it.
2. The fans are labeled 12025—does that mean they're 120mm?
3. Since there are 6 RGB fans to replace, will that make the process more complicated?
My motherboard model is B450M-HDV R4.0, just to give some context!

It looks like your fans are indeed 120mm. Usually, the fan wires are connected on the backside of the case; you might need to remove the side panel to see them clearly. There are typically two wires for each fan: one for power and one for the RGB. Just take a look at the other side of the case to spot them!

Here’s a pic of the other side. I'm still uncertain about which wires to disconnect!
