Just picked up a 2nd hand H100i and it's working perfectly as a cooler. Windows, however, is refusing to install the drivers thus making it completely uncontrollable, and let me tell you 2 high quality fans pushing air through a rad at 100% is many things, but quiet is certainly not one of them! I've had a good search through the corsair forums, as well as posting a thread there, but I was just wondering if anyone here has any experiences with the H100i acting in this way. Oh, if it makes any difference all my other fans are connected to a cooling node and a commander. Link's currently failing at controlling them too, but that's a story for a whole different time. I am really begging to question why corsiar has released any of the link stuff yet. It's clearly not ready for the public, and in my eye (and that's the eyes of an adoring corsair fan as you can see from my rig) it's really damaging to them as a company! So yeah, any and all help would be much appreciated before I lose the sense of hearing in my left ear!! Thanks!!
