The Noiseblocker NB-Multiframe M12-P 120mm x 25mm Ultra Silent PWM Fan is part of the family of Germany's quietest fans. The PWM technology gives your motherboard or fan controller more control over the fan's performance than traditional fans. The new Multiframe® technology uses silicone rubber corners to mount the fan, making it as quiet as possible. The NB-NanoSLI® bearing is also vital in providing the fan with its near silent performance and long lifespan that earns it a 6 Year warranty. Noiseblocker fans are the new standard in the industry of quiet computing!

Note: Fans come sleeved black. Please use the sleeving option below if you want us to change the sleeving to a different color.

NB-Mulitframe® Technology
The high tech multipart chassis has integrated vibration absorbers at each corner, making the fan supported directly by rubber. Even the fan's main framework uses anti-vibration glass-fiber reinforcement.

just referring to its loudness: at 1250rpm almost inaudible, but 1700-2000rpm as case (rear in my case) fan is annoyingly loud.. so i moved it between 2 CPU heat-sinks towers of CM V8 which surprisingly manage to mute it almost completely at 2000rpm. as case fan i would have replaced him. not recommending as case fan if you value your quiet. aside loudness - it''s a high quality silicone mounted fan which i would recommend!

I have three of these in the top of my Corsair 800D. I use a Lamptron FC4 controller. At full chat, they are not even remotely silent. I don''t know what people are talking about when they say this, unless what I''m hearing is the sound of air being sucked through the Feser radiator. That''s certainly possible. I can hear them from the adjacent room. I still give them 5 stars, because they are beautifully made fans, and all things considered they are still pretty quiet for 3 fans at 2,000 RPM.

I would only add to what other reviewers said: 6-year warranty; sleeved wires; and I did not have a vibration problem with the fan in horizontal position. In addition to rubber "ears" as contact points, there is a frame gasket (shown attached in the first FrozenCPU image) that may be used for contact. As long as the contact is firm, there is no vibration any which way mounted. I bought 3 and will get more.

Moves good amount of air and is virtually silent at full speed. PWM feature is great on my Mega Shadow. Push pull with another Noiseblocker keeps my CPU air cooling quiet and effective. Yes it''s pricey but it''s very well built. This fan will endure punishment for years.

Great fans! Have them in a push/pull configuration with a Prolimatech Mega Shadow. Kind of went on a limb on this but glad I did. Expertly engineered and keeps my Intel 920 very kool.
