Fans operate at three pin connections, and I linked them to the motherboard. I set the fan voltage to adjust according to temperatures—obviously. When it's cool, the voltage reduces so fans stop while the RGB stays active; if it gets cooler again, the RGB turns off. I can observe the RGB dimming gradually as the board lowers its power to the fans. Would this frequent adjustment affect the fans? Constantly changing power levels, and sometimes it gets enough to illuminate the RGB, but not enough to activate the fans.

You're describing typical fan behavior where fans increase speed during high temperatures and slow down when cooling is needed. This matches standard PC performance patterns.

Unlikely, enthusiasts have worked with vastly different voltages for years without issues. In fact, many can safely apply 18 volts and still function properly. EDIT: I also own an Antec Tri-Cool fan that’s much older than most forum members. If you blow on it hard enough, the LEDs will activate. It’s still working well after about 23 years.

I think it should be fine.

Yes but more frequently. And as I said sometimes it will get more than enough power for RGB, and not enough to spin the fans. Which would cause some heat maybe? Because that power has to go somewhere.

It depends on the fan configuration, but I'm concerned if RGB is active yet it's not turning. If the motor runs but doesn't spin, it could damage it. I'd aim to keep everything spinning if possible. With low-power motors, it shouldn't burn out quickly, and you'll need very low voltage for normal operation.

Others have mentioned your situation. If the fans keep spinning nonstop 24/7 with constant changes, that’s unusual and might indicate a problem. However, if it happens occasionally even when the system isn’t stressed, it’s probably okay. RGB LEDs are built to adjust brightness based on voltage, so they can handle overpowering conditions but not being completely underpowered, which isn’t an issue.

I'll set the minimum voltage strong enough to keep spinning the fans, even when they run at very low speeds.
