I used a Seasonic Vertex PSU that has hybrid mode on my latest build and I am going to try it out. Just wondering what you guys think or have experienced. My PSU is 1000W so it not stressed in the least except for gaming, and even then it has lots of headroom. I did take note during the install to make sure to have the fan side with the vents up, to encourage natural thermal convection and not trap the heat in the case, as it would if it was inverted. So far so good.
PSU Hybrid mode worth it?

I hate fan noise. I mean I really hate fan noise. But proper cooling is more important than quiet operation.
Still, if fans can be kept quiet while temperatures remain cool, then as long as the fans properly (and quickly) spin up when the electronics heat up, then absolutely it is worth it! And that is what hybrid mode does. It keeps the PSU's fan turned off while the PSU is just loafing along. But when you tax the system and the demand on the PSU goes up causing the PSU's temp to rise, the fan starts to spin. Typically, it spins slowly at first but it will ramp up speed as necessary to keep the PSU adequately cool.
I am assuming your PSU mounts on the bottom of the case and that is why you ensured the vent is up. That's fine. That really does not affect the health or life of the PSU since the fan will quickly override any natural flow of heat anyway. But having the vent up, as you noted, will allow PSU's heat to escape more quickly and that "should" allow the fan to stay off, and silent, longer. That's a good thing, IMO. Did I mention I hate fan noise?

Not surprising. Seasonic is known for quality so it makes sense they would use a quality fan too.
I would suspect it would. The difference being in regular mode, it never stops spinning.
Was it an actual "warning", as in a caution to prevent damage? Or more like a suggestion if you want to run silently longer?
If you hear your case fans, and if it annoys you, there may be couple things you can do while still providing a nice flow of cool air through the case. You might be able to slow down their rotation speeds or swap current fans for quieter ones. Moving a front intake fan to the back as an exhaust often helps. You just want to ensure you maintain a slight overpressure in the case to ensure air enters the case through the air filters - if your case has filters.
Its certainly a personal choice. Unless there's a major fault, it will never over heat and that is a possibility regardless the setting.
Much may depend on the case it is in and how well it suppresses noise. The location of the computer, or more specifically the power supply in relation to the user's ear might matter too. Then there's always the ambient (room/background) noise that may or may not drown out some fan noise. And of course, the user's hearing matters.
I know with my EVGA PSU, my fan is silent at low speeds too. In fact, the only way I can tell it is running is by putting my ear up to the exhaust vent then I can feel the warm air hitting my ear. I credit much of that to my Fractal Design case - an excellent case that is lined with sound deadening materials.
Typically, if I hear a fan, it is either the CPU fan or graphics card fans spinning up.
Odds are, I'm listening to music anyway.
Interesting. Any way, you oriented it properly so it seems you are good to go.
Yeah, if "fanless", as in "passive" or "no fan" cooling is not an option with that supply, then it seems parts of the text for that manual are being used with or was copied from a different PSU.
It would make sense if there was an option for not fan, you would want any heat to rise up and out unrestrictive.
I'm going to stick my neck out and assume you are not going to lose any sleep over this!
