Hi all,
Sorry to dig up an old thread, but I wanted to jump in to say I have the exact same issue on my H115i Pro. In my case, it's fan #2 that is unresponsive. I've tried every setting I can change in LINK (v4.9.7.35), and it's stuck on 1150rpm. Fan #1 behaves as expected. I'm on FW 1.0.4.0
My machine is not easy to access the internals, so I haven't tried swapping any cables, but I've done everything else. Is the consensus that I need to start a ticket with Corsair? I read through the whole thread and didn't really see a solution. My rig info is in my profile, if that matters. The CPU idles at around 37c and the GPU at around 40c, due to running dual monitors. I've switched the pump to performance mode, and I haven't noticed any change in idle temps. Haven't done any stress testing, so once I do that I may drop it back to normal mode if there's no real benefit. That's another topic anyway. :)
Thanks for any advice!
