I will investigate more about the LEDs and report if I find a solution. Yes, the MB header idea was mentioned by OP. I only have the cpufan connected to the MB itself. The other ones are connected directly to PSU so I didn't know what to do with that answer. I guess I could completely disable the LED's but it is the revival of the Lavalamp. Mmmm I haven't decided to go TB on my next audio interface yet but it certainly gives more options since I need atleast 24x24 ins and outs. I have a LaCie USB3/TB2 drive though but i'm not sure if it's a good idea to get a TB3>TB2 adapter for that since I don't know if it actually improves the write/read speed since it's not a SSD. Also a bit worried about how well it will be recognised during startup because of the "TB hotswap problems". Ah so the NVRAM is only/mainly for NVIDIA users? I thought it also played a part for other things. Like if I have a system crash/reboot, it can keep the crashlog in memory despite the powerdown, among other things? @Stork too. Thanks a lot.
