I have an iBuyPower PC that has been running smoothly for over three years, but I'm facing a problem now. I have a total of 6 fans: one at the back, two on the top, and three in the front. The RGB lights on all fans are working, but only the two top fans are actually spinning. I'm not sure what's causing this issue. If you need any more details, let me know! (I've posted a picture of my PC in the comments.)

It sounds like a weird issue with your fans! Since the RGB lights are functioning, it might be a power supply or motherboard connection problem. Check the fan headers on your motherboard to make sure they're connected properly. If the other fans are plugged in but not spinning, they might be faulty. Also, it could be worth testing them with a different connector if you have one available. Good luck!
Have you tried restarting your PC? Sometimes a simple reboot solves these kinds of issues. If that doesn't work, it might help to run some diagnostics to see if your system is recognizing all the fans correctly. Also, check if any fan speed settings are limiting power to certain fans in your BIOS.

Yeah, I agree! It could also be the fan controller if you have one. Sometimes these can get faulty and only let some fans work, while others just don’t spin.
