Replacement fan for Ultra 6

I just successfully replaced a rattling/clicking case fan (the big one on the top) on my ReadyNAS Ultra 6 Plus with a Noctua NF-F12 PWM 120mm Case Fan. It works. It's quiet. It comes with a four-pin connector but it still plugs into the 3 pin connector the old fan was plugged into on the ReadyNAS. Is there a better or different fan that would work?

If that's not a rhetorical question, yes. The fan you chose will probably cool the NAS just fine, but it's louder than and has a lower maximum airflow rating than the 3-pin Noctua NF-S12A FLX.

It's kinda pricey for a case fan, but the quality seems to be great

Agreed on both counts, although it's available for less than what you paid: Amazon sells it (and the NF-S12A FLX) for around $20.

It was an easy installation. Just need a phillips screwdriver to remove the sides of the ReadyNAS enclosure, the plate the fan is screwed to, and the old fan.

Just make sure that it's blowing the right way: Label side OUT for the fan at the upper rear of the Ultra 6 Plus.

Great success.

Congratulations. Replacing a noisy fan is very satisfying.
