I'm a first-time PC builder and recently assembled my own computer. However, I'm facing some problems with the TUF GAMING B650E-E motherboard. First, during startup, the BIOS doesn't recognize the case fans. I followed an article for wiring and connected the 4-pin RGB to the chassis fan on the motherboard but left the 3-pin unconnected. I purchased a fan/RGB controller hoping to solve this, but it seems I need a specific NZXT controller to use the 3-pin connector. Meanwhile, the CPU fan works fine, but I'm wondering if I messed something up or if there's a bigger issue at play. Also, the motherboard's USBs and ethernet port are acting up—they disconnect intermittently, causing my internet to drop for a few seconds while everything else runs smoothly. When I connected a controller to play Borderlands 2, it disconnects after a while, which is frustrating. I've heard this could be related to the motherboard, or maybe something else is wrong? I'm also running Pop! OS, so it might be a driver conflict too. Any insights?

Regarding the USB and ethernet issues, they could indeed be related to driver problems, especially since you're using Linux. Make sure you have the latest drivers for your motherboard and any peripherals you’re using. If things are acting finicky right after boot, a BIOS update might help stabilize things. Some users experience similar problems, so don't hesitate to check forums specific to your motherboard for advice or updates. Also, it might be worth trying a different USB port or cable to rule out hardware issues.
It sounds like the main issue with your fans is due to incorrect connections. The 4-pin RGB connector is meant for lighting, not fan power, so that's likely causing the problem. You should really connect the fans using the 4-pin PWM connectors into the motherboard’s fan headers. For the RGB, look for 5V ARGB headers on your motherboard to connect the 3-pin; these are usually at the edges on the TUF boards. If you’re stuck without enough headers, only then consider getting an RGB controller if you absolutely need more control. Don't worry, you can easily fix the connections without needing to buy a whole new setup.
