Be Quiet ! BL046 Pure Wings 2 120mm, cooling fan, Black

Great fans, very quiet and well worth it for the performance.

The BeQuiet! BL044 Pure Wings 2 fan is fantastic. I had the bearings go on an older non-descript fan that I had for several years. After having a great experience with beQuiet! 's CPU heatsink/fan system I installed a year ago I opted to go for another of these brands fans. I was not disappointed. Installation was as simple as finding a free fan connection, plugging it in and screwing it onto the case with 4 screws, granted I had to use my original case screws but you do get some shorter screws provided in the box. I power the unit up and bam, the fan spins, great airflow and running 5 degree's cooler and I can barely even hear it with the gentle hum of airflow moving through it, it is REALLY quiet. Superb fan, just be careful of the depth of this unit if you have a large heat sink (that I do) it came close but fitted fine.

For clarity, I purchased the 3pin 120mm 1000rpm BL047 version of this fan (NOT the 4pin PWM version). I purchased these to replace some Corsair fans that came with my AIO (280mm radiator H115i) The Corsair ones sounded like someone had a vacuum cleaner on. These ones on the other hand are quiet as anything (same speed as the Corsair ones were used at). I can say that these are less airflow than the supplied Corsair ones, BUT they do keep my temperatures at around 50 degrees when stress testing the CPU (the same as the previous Corsair ones). Also worthy of note is that they are not being used at the full 12V by me (as the Corsair ones weren't either). So if they can keep my temperatures down with that in mind, they should have no difficulty at 'normal' speed. Would I buy them again? Yes Would I recommend them? Yes Are they quiet? Yes they are - I can barely hear them with the PC sat next to me in a Lian Li Dynamic case (beautiful case BTW!). Which way around do I fit them? The logo side should be on the intake side (air in) and the tech details side is air out or exhaust. How quiet are they? At the speed I'm running them at, I could hear a fly fart! At full speed I would imagine they'll still be fairly quiet. I can only suggest that the people who say these are not as effective (air flow wise) as they imagined they should be, have either fitted them incorrectly (the wrong way around may be?) or are expecting something like a 12 inch fan for airflow from these. Also bear in mind, these rotate at half the speed of most 120mm fans. I have no idea how long these will last, but a 3 year warranty gives me some confidence in the product.

I replaced two 13 year old 7 blade 120 mm CoolerMaster fans with these. This is because working from home I've started to get irritated by the constant turbine rumble of my PC. I already have a quiet XFX PSU and a Be Quiet! CPU cooler, so thought I would give these a go. Is my PC quieter? Yes, a bit, though it seems that my old fans were't as bad or worn as I'd suspected. Is my PC cooler? Yes, a bit. I reckon the average temperature of components at idle is a few degrees cooler. I've also noticed than my GPU fans are quieter when I'm gaming. All in all, these are decent well-made fans for the money. You could certainly do worse but there is better out there at a higher price point. If I had a modern case I think I might see a bigger reduction in noise and temperature.

I have "standardised" on VCR-style mATX/ITX cases housing virtual servers that require small 80mm fans - 4 of them. As they are deployed in residential/office they need to be quiet. Air flow for my use is less important as the combined load on the servers is low. Thus I have been searching for quiet PWM fans that are also cheap. While the Arctic fans are very cheap, even the PST CO are very loud even at low RPM (200 min). Yes, they do move air well if you need that and are very cheap but they are loud and they start rattling after about a year or so. Thus I have been on a quest for quiet fans. If I had the money, sure go for Noctua. But these are much cheaper and really quiet. For my use they are great, sure they don't move lots of air especially at low RPM but they are quiet. At max rpm (2000) they do move decent amount of air at OK noise but don't expect Arctic level of air (2200 rpm). Note the included fan screws are silver - so may need to buy some black screws; also no splitter which for some motherboards with say only 2 fan headers (since I use 4 fans) I needed 2. Arctic fans do have built-in splitters... Overall if you want quiet and cheap but don't require lots of air these are ideal.

High quality durable fan. Great!

When buying this product I was contemplating whether this product would be a success because of the low price, but to my great surprise it is amazing. First of the installation was as easy as any other fan, four simple screws and a connecter to provide power. I currently use this fan as an exhale and what a great job it does. It runs a very acceptable speed and provides excellent airflow throughout my computer system. This was very important to me that everything stays cool, and to safely say, no issues what so ever. The mix of affordability, noise and performance makes this product a massive success and I don't see why you would go elsewhere. Although if you're looking for RGB you could be pushed elsewhere as this product does not provide this. As an exhale this was not too important to me. Overall this is a great product and do not regret the purchase at all.

Malgré sa taille le ventilos est très silencieux ce qui est très agréable !

Parto con il dire che non sono fan-boy di questa marca, ma ne riconosco i numerosi pregi; come: la notevole qualità costruttiva e la notevole qualità dei singoli componenti usati; l'estetica molto pulita ed attraente e le ottime prestazioni in ambito acustico. Questo modello, il BL046, è una ventola da 120mm a "TRE PIN" ottimizzata per AIRFLOW; ciò vuol dire che questo tipo/modello di ventola (intendendo l'ottimizzazione per AIRFLOW) è ottima per far circolare aria all'interno del case, ma se fatta funzionare contro ostacoli, come ad esempio radiatori, se ne vanno a ridurre le prestazioni; il a TRE PIN indica il fatto che i parametri di rotazione della ventola non possono essere modificati direttamente tramite la MoBo (come invece può essere fatto per una ventola PWM), i parametri in questione, possono essere modificati se si va a modificare il voltaggio che la ventola riceve; ma personalmente non mi preoccuperei troppo di cambiare i parametri di rotazione dei questa ventola dato che è molto silenziosa in partenza. Passando ora alle prestazioni di questa ventola; sono ECCEZIONALI ! Il prezzo di 10€ è ottimo e a mio parere li vale tutti; è di una silenziosità spettacolare in tutte le fasce di funzionamento ed anche a Full-Load (caricata al 100%) l'unica cosa che sentirete è il rumore dell'aria che viene sposta dalla ventola. In definitiva consiglio questa ventola a tutti, specialmente a quelli che stanno cercando ventole da mettere nel proprio PC per ridurne il rumore ed al contempo avere delle ottime e solide ventole all'interno del Case.

Fiquei satisfeito com o pedido feito, pois recebi conforme o desejado e dentro do prazo de entrega estipulado

Excellent.

Estos ventiladores son una maravilla apenas se escucha que están encendidos.
