Silenx EFX-12-15 Effizio 120x25mm 15dBA 74CFM Fan

There are better fans, but not at this price point. Very quiet and moves a lot of air.Only warning about the fan is it's designed for unobstructed airflow. This is not an optimal fan to use on a cpu radiator because it will not perform as well as a fan made for higher static pressure.Works well when placed against a grill and used as an inlet or outlet fan.

Just what i needed and wanted. Very quiet and efficient. Does the job. I would order it again. Hope this helps.

This 120mm fan isn't as quiet as the specs would make you think. I bought two of those from outletpc, and they both make a considerable louder noise than its 80mm counter part, which is as well rated at the same 15db. The 80mm version truly is silent and quiet, can't hear a thing. But this 120mm version makes this subtle woosh sound, and it's annoying in a home theater pc environment. It's not loud by any means, but it's definitely noticeable in a quiet environment, especially if you're aiming to build a silent pc or htpc in my case. A bit disappointing consider i bought two of those thinking they have the same silent signature as the 80mm version i bought. But not at all. Based on perception, i would say this 120mm version is probably 5~10db louder than its 80mm cousin.

It is very quiet and very fast! I would definately recommend to anyone looking for a case or cpu fan.

Great silent fan would recommend it to any one good for gamers trying to keep their system cool and very low temp

I use this fan as a vent fan for my rv refrigerator. It moves a ton of air and is very quiet. Second rv, second fan.

An awesome improvement over the ones we replaced. Love them, definitely a five star purchase... Amazingly quiet and very easy to install.

Great replacement for your stock case fans. I am running a decently fast computer and these fans keep up to gaming while not keeping me up at night.

I was determined to get noctua fans and took my sweet time looking at specifications on specific fans. These were second best in specifications to one particular set of noctua fans. However the noctua fans were 20.00$ a piece. I as well needed two.. So i came across this company for high airflow with low noise.. To my surprise these were quiet! And moves air! The only sound i could hear with the side of my case open was air moving. No noise what so ever from the motor..I purchased two of these for my cpu cooler because thermaltake fans suck. Loud as they come. And these were the perfect replacement and even matches my color scheme.Noctua just released black fans finally, not the brown poo poo color that was inspired by the toilet... But for the price and honestly the difference in sound is not noticable side by side. I would rather support a growing company that has color options and nice fans then to pay out the "brown hole for brown"to wrap up this review i highly recomend these fans. They are as advertised in both db and cfm's.

Not that silent, but good enough.
