There's this which is fairly new but gaining a lot of tractionHi again.
Just doing my homework - looks as if Linux support is there. Do you have a link to information about tweaking fans? Is it hard? From your comment it seems that they are initially set on full (and a little noisy) but that I can dial this back a bit. Starting on full seems the safest idea.
I'll probably go for the correct memory straight off (even if I have to mortgage my granny ;-). Everything else looks good to me.

In depth details of device support added is here: https://forum.corsair.com/forums/topic/189584-icue-link-system-hub-on-linux/
Another option is to dual boot or do a windows VM, install iCue and set your devices, then save the settings locally to the device itself so it runs that way in Linux. That's the approach I've taken.
