Case fans dimmer than they sould be

Mackaz · July 31, 2023

I have 7 RGB fans in pc, 6 in case and 1 on cpu cooler. Case fans are rgb daisy chained and conected to 4 pin RGB header on mother board, CPU fan is connected stright to other RGB connector. Today i noticed that my case fans light much dimmer than cpu one. Regularry I've had set static color but today I was running color cycle when they dimmed. I tried diffrent software (aourus rgb fusion, open rgb) and bios settings, but when all are set to maxiumum brightness still they are dimm. I wonder if something on motherboard could broke or its something else. What do you think i could do to fix them?

Motherboard Aourus B450 Elite
Fans Silepntium PC Corona 120 RGB

You could've overloaded that single RGB out on your mobo and killed it. Try connecting only a single fan and see how it glows.

all of them? 5V ARGB is only rated at around 100-110 LED at its THEORETICAL maximum, let alone in the real world where its more like 50-80 LED. Try one RGB fan but yeah sounds like the header just choked on power. Get a separate ARGB controller with SATA power.
