SilenXiXtrema Pro Fan, 40mm x 20mm x 20mm, 6 CFM, 3000 RPM, 14dB Noise, Desktop, Graphic Cards, Gaming Console

Can't judge longevity of product yet but looks to be of good quality.

Why did I wait for the OEM fan to fail? All that time listening to the noisy fan when I could have used one of these instead.

Great product -- very quiet. Can barely hear it. As long as your application can handle a lower cfm rating, the silence is amazing.--update -- they were quiet as described for about 4 months. I have 3 in my switch -- all 3 started 'rattling' after about 4 months

The fan blades are unbalanced, so while quieter than most fans, it adds a low pitched hum to the installed system, even using the rubber mounts.

When I first got the fan I hooked it up and it did not work. I was perplexed at how a brand new fan would not work straight out of the box. A quick call to Silenx tech support helped me out though. Maybe it will help others too. I explained to them my dilemma and they suggested that I press down on the fan blade to be sure it was seated properly. I thought "why not" so I did and it clicked into place. They explained to me that sometimes it happens that the fan gets dislocated during shipping and must be pressed back into position, It is designed that way so that you can remove the blade to clean and lubricate the fan in the future. Great Idea, just wished they would have explained that in the directions. Otherwise a good quiet fan that moves a lot of air!

Love it and will buy it again from the seller

Quiet and efficient. Just what I expected

Super quiet, high quality casing and comes with helpful adapter, screws and rubber mounting pins, highly recommended
