SilenX IXP-34-16 iXtrema Pro 60x25mm 16dBA 18CFM PC Computer Case Fan

Very quiet and moves a lot of air for its size. The first one lasted about a year then began to rumble. I hope the second one lasts longer...

I replaced the noisy fans in the Nanocube 28 gal saltwater tank with these 60 mm fans. The stock fans are 50mm, but these will fit snuggly. I didn't screw them in, just put a couple strips of tape on the wall so they don't slip down-this will make sense when you see how snug they fit. Finally the "cube" is quite! Note that these have three wires and the original fans have two. You will need to splice the black original wire to two of the new fans wires and the red one to one new wire alone. I little trial and error and you will figure out the arrangement. Also, make sure that no wires can touch the fan when you seal it up. Tape them down if you have too.

A excellent replacement fan for a external drive bay. Flows the same amount of air as the old one. However it's so quiet I had to visually check if the fan was actually on. So my relief it was working.

Replaced the Fans on my BioCube 29 gallon hood - nice and silent. It did take some modifications and wiring to do it (instructions can be found online), but it was not too bad if you feel comfortable doing that sort of thing.

Very poor lifetime on this particular example. I doubt that it had more than 400 hr of use on it.

Used this in place of a noisy fan in a power supply. Pleasantly quiet.

Replaced the fans on my NanoCube12 and Biocube 29 with these and now I don't have to deal with that annoying loud hum that the stock fans had.

excellent fans very Quiet
