Lian Li EX-503, Changing the stock fan, recommendation?

[IdontexistM8]

Picked up this 5-bay RAID/JBOD enclosure in the last week, it comes with the Lian Li stock fan LI121425BE-4-A. While it's not loud, it's not exactly quiet either, pretty much slap bang in the middle, but not unpleasant. However I'd prefer something a notch lower, perhaps with a LNA. So since it looks easily replaceable can anyone provide a recommendation?

Thanks

The LI121425BE-4-A is a 140mm fan, i would replace it with Noctua NF-P14s redux-900 Fan (140x140x25mm, square frame 3-pin, 900rpm), another option is the Antec True Quiet 140, but im not sure the mouting with the rubber edges might be difficult.

As you can read on the label, it's a 0.14A fan with a starting voltage of about 7V. SPCR tested it here.

So you need a 140mm, 0.10-0.20A fan, with a starting voltage no higher than 7V: that one could be a good candidate, which is 3-5dB quieter through the whole range.

Thanks for the suggestions so far. I would lean towards the Noctua ATM.

I might have a spare Zalman Fan Mate 2 knocking about, if there is a way of tucking it away inside at the front of the unit I might try that initially after fully setting the unit up.

Found it quite quickly The only place it could go inside the unit is the floor, that would mean it's inaccessible if there's a drive in the bottom bay but with 4 or less drives it's perfectly workable.
