I ordered an new computer now, and I'm getting the corsair ax760i, some domniator ram, and maybe I get an corsair h100i cooler later.
But what's kinda interresting here is something called Corsair Link, have anyone looked at that?, someplaces it seems that its using i2c, would be cool to connect to this to see what can be done.
Corsair have had some fan controllers and other stuff to monitor powerusage, temperatures, fans and so on, but it seems kinda difficult to find now (Some said that it even not in production anymore, the Link Commander that is, what now that is.. )

You might like to have a look at this thread on the Corsair forums I bookmarked a while ago - http://forum.corsair.com/v3/showthread.php?t=120092 (http://forum.corsair.com/v3/showthread.php?t=120092)
Corsair Link is the software that talks via USB HID protocol to a controller (e.g. built into the cooler), with the individual devices (fans etc.) connecting to it talking what appears (from the contents of the USB HID packets) to be SMBus or I2C.

Havent received my stuff yet, but from videos it looks like there is an 4pin connector in the psu, and an usbdongle with the connector?
but with the Corsair Link Commander, it seems like that one replaces the usbdongle, and have lots of those 4pin connectors (or maybe its' more pins)
I found one used corsair link, maybe I should buy it to find out how that one is made, i cannot find any new ones, but they seem to have another model now, with so called nodes, GPU node, Lightning Node and so on, but the information on Corsairs webpages is lacking..

There's a good chance it's using PMBus. If you have the original controller, it can be very helpful to attach a logic analyzer.

Yes, I think I have seen PMBus mentioned, reading the thread at the corsair forum more, lot of code are up there.
