SYS FAN fails "out of spec"

So for a while now I've been happily using a Noctua for my system fan.... I decided to swap the Noctua for a Noiseblocker NB-eLoop B12-4 Ultra Silent Bionic Blade Fan.... I go to the Health page and for some reason the Noiseblocker stops spinning randomly with the error "FAN SYS failed" and "out of spec".... Is the Noiseblocker honestly 'out of spec' in terms of RPM/power draw for the RNPP? I wouldn't think so!

Judging from what a quick Google search showed, your new Noiseblocker fan draws 320mA at 12V. That's more than FAN2's 250mA max, so yes, it's out of spec.

The Noctua fan you switched from draws only 1.08W at 12V; its current consumption will remain within spec across its entire RPM range.
