Drscoop Posted September 28, 2020 Share Posted September 28, 2020 OK, so I have a BeQuiet cooler, with a single 120mm PWM fan on it at the moment. It runs off the CPU header which is rated at 2A. Mobo says the CPU fan header is auto-sensing, so my understanding is that I could, if I wanted, pop on an SP120 RGB Pro fan instead of the stock fan, to match those in my case, with power off the CPU header (now speed controlled via DC, not PWM) and RGB off the Lighting Node Core (currently 2 positions free...). Given that, I guess that I could also, if I wished, pop another SP120 pro on the back of the cooler (I have the attachment clips), use a Y splitter to run both fans off the CPU header (0.6A total off the 2A header) and run both independently off the two free ports on the Node controller.... (I could run the 2nd fan power off a spare case fan header, but seems to make sense to run them both as CPU fans if I can. I assume, also, that a 12V fan splitter and PWM splitter are the same, but the 12V fans just use 3 of the 4 pins?) Am I missing anything silly as to why that might not work?

Corsair Employees Corsair Mint Posted September 28, 2020 Corsair Employees Share Posted September 28, 2020 Looks about right. One thing to note is that when you issues commands to the Lighting Node Core, it's for a single type of fan. So, all the fans connected to the Lighting Node Core would need to be a single type. For a different type, say if you had SP RGB PRO and LL, you'll need separate Lighting Node Cores. Link to comment Share on other sites More sharing options...
Drscoop Posted September 30, 2020 Author Share Posted September 30, 2020 Cool, thanks. Yep, all the four current fans are SP120 RGB Pros, so I'd just add another one or two of the same... Link to comment Share on other sites More sharing options...
