Well, yes, which is why I find it weird that one works while the other doesn't. It feels more like a power or current issue than anything (since apparently making the fan smaller or slower fixes it), but that's just me guessing anyway.

Upon further testing, it seems the F12 3000RPM works without issues, surprisingly. So it seems that the issue (at least with this cooler's controller in particular) is limited to the 140mm 3kRPM model.

The H115i is quite literally the only device I've seen so far to exhibit this issue, with even Corsair's own older offerings working fine with the fans, so if anything I'm more willing to give Noctua the benefit of the doubt than Corsair (not to mention Corsair's long history of software and firmware issues).

I assume that it's an issue introduced in their most recent controllers, considering that I used 3000RPM F12s in my old OG H100i without issues? Has Corsair ever acknowledged this issue?

Hello, I just got a new H115i Platinum, but it seems that when I hook my Noctua NF-A14 iPPC-3000 fans to it, the controller goes out of whack. More specifically, setting it to any of the default profiles or a custom fan curve causes them to never spin, while setting them to any fixed RPM other than max causes them to spin up and down nonstop. If I plug in the included fans (which are currently installed somewhere else in the case), it seems to work fine. Is this a known issue with the built-in fan controller? Is there something I have to do in iCUE to make it work with the non-default fans? Thanks in advance.
