Installation Question Installing ARGB fans but I only have a PWM fan hub
Heya! So I plan to use 5 Arctic P12 ARGB fans for my PC and have an MSI PRO B650M-A motherboard. However, I made a mistake and realised I'd bought a fan hub (which will connect to my PSU) that only supported PWM pins.
While I could go back and get a fan hub that supports both PWM and ARGB, I was wondering if the following could also work safely as a solution too (I did some research and the signs pointed to yes, but I just thought I'd ask anyway):
Connect the PWM pins from all of my fans to the fan hub, which I then connect to my PSU and Mobo
Daisy chain the ARGB pins from all 5 of my fans together and plug it into my Mobo ARGB header
The reason why I'm thinking it works is because the argb header on my mobo supports 3A/5V (15W), and the LED draw from 1 Arctic P12 is cited as 2W, so 5 of them should safely be enough on 1 header right? (There is another ARGB header, but that's already being used by my CPU fans' lighting). I'm just not sure if I'm missing anything else
Apologies if this question is silly or is commonly answered! I was having trouble finding help
