From the vibration pads to wiring sleeves, it looks like a well engineered product. Looking at the fans compared, if installing on a case/radiator I would go for whichever of the two, however if installing on a cooler I'd go for the Noctua as it has anti-vibration padding. Fans on CPU coolers are loosely installed, so there can be some vibration noise where those pads would be useful, but for case mounting where the fans are rigidly attached, not so much.
Good fans don't vibrate much.
Something Noctua didn't master while focusing on marketing instead of actual product engineering.
I've had both NF-P12 and NF-F12 come with heatsinks and in vibration those are absolutely the way worst fans I've touched in 20 years PC has had fans.
At least NF-P12 has OK good noise profile, but NF-F12's marketing geometry gives it restless noise profile with sharp spikes in it.
And you're completely wrong about case and fan vibration.
If you care about noise, vibrating fans are the worst thing to add into case:
Case is made of really big thin metal sheets, which lack rigidity to resist vibration and start acting as loudspeaker diaphgram when exposed to vibration.
That vibration amplified by case has always been the biggest noise source in mechanical HDDs.
Hence soft HDD mounting is all above budget level cases in last dozen+ years.
And fan isn't any different if it's badly vibrating.
(maybe Noctua finally copied also motor besides main blade geometry from Gentle Typhoon)
Any reason why he's matching noise levels, rather than rpm to measure performance?
If noise isn't concern, you shouldn't be looking at Noctuas at all but Deltas.
