NoiseblockerNB-eLoop Series B12-4 120mm Bionic Loop Rotor Fan, 2400rpm, 34dBA

This really is an well designed and implemented 120mm case fan. At 2400rpm it is a bit loud but has wonderful flow! I also tried this fan on a 120mm AIO water cooler radiator and was Very impressed with the pressure this fan puts out. As a set of case fans, tuned to just enough air flow to chill a powerful workstation, I found these fans quite reasonable in the noise dept while moving a good deal of air... Neat Design! these are white with black frame but there are also Black versions - both look nice in the right chassis - I mounted these in a white Mesh case - quite attractive I think and the client was happy with the result!

These fans overall are really good looking and high quality. Unfortunately these were advertised in the description as “2400rpm(pwm)”, these are in fact NOT pwm controlled and if you are lookin for pwm fans don’t buy these. I might have to return a few as they don’t make fan splitters that allow you to control dc fans. I should have known not to trust amazon, if you want to buy these fans they are 12 dollars on Newegg. Much better deal, I bought these from Amazon because I thought they were pwm, which in fact they were not.

Amazing fans!!! They move incredible amount of air at a vey high pressure, so they're good as both chassis fans and radiator fansThe built quality is superb, the anti vibration mechanism works great, and the color scheme complements most cases perfectly (I have 2 of these in my Fractal Design Define Nano S case, one at rear and one at the bottom)One thing to note is that, while they're very quiet compared to other companies' fans of similar quality (like the Noctua's Industrial fans) , at rpm >1000 the fans start to become a bit audible and at >1600 their noise level is quite annoying. However, I knew that when I bought them. That's why I hook them up to this fan controller  Nzxt GRID+V2 AC-GRDP2-M1 12V Digital Fan Controller with Molex 4-Pin connector . The problem is that, at the moment (with the fan controller's software, CAM, at version 3.1.2), if you try to lower the rpm to <40% the fan behave erratically - either speeding up randomly and then, moments later, speeding down or, sometimes, disconnecting completely for a few moments before reconnecting with the software. Also, at 40% the fans should spin at (2400rpm *0.4)= 960 and yet they spin at ~1470rpm. However, all of these are problems with the fan controller that NZXT is working on. The fans themselves are amazing.I would totally recommend them to anyone

Either these fans are not rated properly DB wise or I got a bad one. Usually you can barely hear everything in my PC unless I'm actively gaming. Even then it's still not loud. From the moment I started my PC up this fan eclipses all other sound made by my PC. My roommate opened his door and came out to check what it was. Returning this one and hoping to get one of the others.All other fans in my case are 28.5-29 DB. A 3 DB increase is barely noticeable and a 6 DB increase is noticed but not to the extent this one was.

Incredible! I am super impressed with these, they move almost as much as the noctua industrial 3000rpm ppc... Minus all the noise.It is still very audible on max rpm, but it's nothing compared to the popular corsair fans. Noctuas are fantastic but these can go head to head with them--these eloops also look very stylish.The plastic blades feel kind of cheap, so does the housing/frame.Totally would recommend this to any of my friends.

I honestly wanted to love these fans.The main problem here is the amount of noise and the type of noise these fans put out.Anything over 50% is a annoying loud/buzz coming from the fans motor.If you want a silent PC, skip these. If you want airflow and are okay with the noise, get these.

BUY THIS FAN! great performance! Massive airflow! VERY quiet!

Weren't quite as quiet as I had hoped.

These fans are really quite, i have 6 running on my Radiator set up and can barely hear them at all. just a very slight wind noise.But the only down side for me was i had to go through 9 Fans to find 6 good ones, so be prepared to RMA until you get all the good ones!! And when you do you can run them and forget all about them.

Hatte 2 dieser Lüfter und beide machen bei niedrigen Geschwindigkeiten ein unerträgliches klackern.Dieses klackern hört genau da auf, wo der Luftstrom deutlich hörbar ist.Habe mich lange damit rumgeärgert und bin schließlich zähneknirschend auf die neuen Noctua umgestiegen, da diese doch recht teuer sind aber dafür wirklich konkurrenzlos leise.Einen der beiden Noiseblocker eloop konnte ich zum noch umtauschen und habe auch anstandslos mein Geld zurück bekommen.Man muss sagen, dass die Lager einmalig gut laufen und sie auch bis zu einer gewissen Drehzahl keine Luftgeräusche machen, daher auch die 3 Sterne.... aber bis sie dieses Klackern nicht in den Griff bekommen sind sie für Leute, die im stillen lernen wollen unbrauchbar.

Perfectos para un intercambiador. Tienen q estar x encima de 1550 rpm (36%) por debajo se escucha un ligero ruido q desaparece a partir de estas rpm.Al ser de 3 pines es necesario tener un controlador para poder variar el voltaje. Al maximo 2600-2700 rpm suenan bastante, es un sonido natural e incluso "agradable", solo lo puse al maximo para hacer pruebas.Todavia no experimente mucho con ellos, pero me parece una buena adquisicion, cero luces, buena calidad de materiales, buenas caracteristicas, ahora a ver como envejecen.

Prima di acquistare ho cercato sul web migliori ventole per pc e mi è uscita la noiseblocker come brand. Dopo essermi documentato ho deciso di acquistare questa bella ventola che vantava una super potenza di aria e bassissima rumorosità. Bene mi aggiungo all'elenco di coloro che hanno affermato questo. Davvero un gran flusso di aria e di silenziosità. Consigliata

Also leistungsstark ist der Lüfter schon. Und wie.Wenn man die Hand gegenhält um die Saug- /Blas-Kraft zu testen, wird die Hand fast durchgesaugt.8°C konnte ich aus dem Gehäuse wettmachen.Leider ist diese Leistung auch ordentlich laut im "Gebläse".Wenn man meint man könnte den Lüfter mit ner Lüftersteuerung drosseln, hat man sich geirrt.Die Stufe nach 100% ist: rattern/ surren und der Lüfter dreht fast gar nicht.Ich weis net ob`s an der Steuerung liegt, aber bei allen starken Lüftern habe ich diese Eigenschaft zu verzeichnen.Immerhin gibt der Hersteller 5 Jahre Garantie.
