To be honest, the trade-off is not really worth it, I will put again my AIO fans to exhaust mode. I did tweak a bit the fan curve of my front intake fans to run on higher rpm, hopefully it will help a little bit. As for the gpu performance, made a benchmark before & after the change, even if running on higher temperature, my clocks didn’t suffer.
What will continue from now on, I will monitor how high the AIO fans do go, before the change they were sitting at 1800-1900 RPM and coolant had a max of 38C, mostly staying at 36, will play a bit with the custom curve to see what I'm getting.
Anyway, leaving aside the AIO performance, today I played a bit with the corsairs Hubs, which i have the Lightning Core Node (from the case) and the Commander Pro (from the AIO). I did plug the rgb connectors from case fans from the core node to the commander pro and to my surprise, it works, the iCue app detects all the rgb fans, which means I am safe to remove the lightning core from my case, more space and less wires( as long as I have max 6 fans, which the case supports). However, what I didn't understand, why the fans don't spin up if I connect them to the FAN slots on the commander pro.
If I close the iCue app, they do start to spin up, if I reopen iCue, the still spin up but on Cooling tab I see still the same 2 fans from my AIO and coolant reading, no extra fans. Is there a logical limitation here?
