I'm pretty sure it's gonna pass 10 year mark on 0 fan mode, so yeah if it has good components and is rated for ~50 degrees celsius operation what you said is not going to happen at all.
And plenty of us do care for PSU noise, it's not that important if it does have 0 fan mode or not, a 600-800 RPM fan of good quality is gonna be inaudible, what's more important is the max RPM of the fan, and how good the speed curve is. And RMx have the lowest max rpm fans together with the original Superflower Leadex I platinum and the Aerocool Project 7.
for those with their PSU on the bottom of the case maybe (but those I avoid & many others do)
but if the PSU is at the top of the case then case heat reaches it, and PSU fan can be useful to exhaust the air out of it
there's several on Corsair forums who say their Corsair becomes too hot to touch for more than a few seconds in summer even if the PSU's on medium load because the fan won't spin
long story short IF the PSU's at the top of the case
(like in most cases) then passive PSU's should be avoided like I said it raises not only PSU temp but also case temps (especially is poorly ventilated cases eg. mine is an Antec Sonata 2 so I can't risk putting a passive PSU in there especially since there's already a gtx980 & a hexacore CPU in there lol)
and noise? quality PSU fans make insignificant noise compared to CPU or GPU fans so who cares tbh
best choice is semi-passive (hybrid) PSU with low-fan mode on low & medium load (with a switch to enable 0-fan for those who like this despite the risks). Seasonics have those iirc
the very fact Corsair didn't include a switch for passive mode for their RMx & RMi is suspicious
