be quiet! Shadow Wings 2 140MM Case Fan, Rifle Bearing, Black, Screwless, PWM, 14.9dB, Anti-Vibration Mounting, Rubberised Fan Frame, Anti-Vibration Mounting

Bought these to replace a cheap Boyu aquarium fan. In the scorching heat of the week that is the British summer, the Boyu fan is comparable with an airport runway in terms of noise, I bought these to replace them.Running 3x Be Quiet fans directly from a 12v (linked to a temp controller) about 3cm from the surface of a 75 gallon aquarium, they have achieved the same result as the bank of 6 Boyu fans, about 5-7°C below ambient air temp.They are so quiet (I mean, they are silent event with my ear against them!) I will be replacing the fan in my LED lights with these too!If you are looking at doing a 12v direct, the middle is the 12v. One side is a 7v control and the other ground, I never had issue applying - to 7v (trial and error).

I bought these to replace my NZXT case fans, which were rattly and loud after years of usage, and I have to say--what an investment! There's next to no noise coming off these and my graphics card is louder than them!They come with easy mount pins rather than screws, which hold them on using friction on the pre-installed rubber dampeners.It might be worth mentioning however; if your cases fan holes are closer to the edge of the case, then you might have trouble putting the side panel back on after installing them because the pins domed heads stick out a little (see image above).Aside from that minor thing, they're honestly a fantastic choice for silent cooling and they have a 3 year warranty.They feel quality, they look quality and they ˢᵒᵘⁿᵈ quality.

What a bliss, these PWM are just absolutely silent even running at high speed.If like me you like a silent machine yest cool machine this is are the best cost/noise/CFM that I manage to find, even less costly than the "normal" ones.I've an AMD 3700X underclocked (yes you're reading right - under) in a mini-ATX box and these fans are the best to keep it cool even at full speed and SILENT!!!Just need to replace the back one with a 120 mm and the CPU cooler fan, all of them will be Be Quiet for sure.It is worth every cent/penny no coil winning, nothing.... nothing but just the sound of air passing through air....

Their fans, however, are without a doubt perhaps their single most impressive product. As a manufacturer, they are constantly looking at ways to provide the best performance possible while keeping low noise levels at an absolute minimum.In that regard, the Shadow Wings 2 range certain fulfils the remit. Not only that though, but even in terms of aesthetics (and yes, there isn’t an RGB in sight) the fans rippled wing design and even the basic outlay of the fans look fantastic.

I've had this fitted along with my other 3 fans from be quiet!So, four fans spinning at full speed, the noise they make you can hardly hear at all!Compared to my old fans which even ONE of those was much louder than all four of the Silent Wings combined!My I5-3570k Processor is overclocked to 4.5Ghz - So the cooling is essential.I'm baffled with regards to how they make fans, this silent, but STILL out-perform your average 120mm cooling fan.I find myself checking the temps and sometimes putting my hand directly if front and behind to make sure they are working, the genuinely are that quiet!If you want to overclock and/or you want a VERY quiet system, In my opinion, thesde are amazing!

i have all my fans set to 900rpm 6 in total they are very quiet and the air flow is very good for a low speed there all 140mm so get more air flow that way . with the push in clips to fit was a little concerned at first but they work well and take seconds to fit a fan no more screws BeQuiet! Shadow Wings 2 i paid 14.49 each the look of them is nice too as they look more like a jet flow feel then standard boring fan all in all recommend they are helping keep rtx 2080 super and the dark rock 4 cool they do such a good job my x570 on bored fan never kicks in as thats set to start at 60c all the m.2 divers are in use and they about 40c max as i have corsair fans before were good but load

I installed these instead of the Silent WIngs that came with my BeQuiet 500 case. So much quieter and PWM too.Easy to install with the rubber grommits and push pins, just wish the wiring connector was a few inches longer to allow for neater cable managment.

Expensive, but virtually silent at 50% speed.I love be quiet! fans... I've got 3x "Shadow Wings 2" case fans and I use a "Dark Rock 4" CPU cooler. I've also got one of their Pure Power PSUs, which is the quietest one I've ever owned.My only regret is that it's not worth paying extra for PWM versions unless you intend to run the fan at very low RPM. Most modern motherboards can control fans perfectly well at speeds above 40%.
