be quiet!Pure Wings 2 140mm, cooling fan

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? YesWould I recommend them? YesAre 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 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.

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.

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.

1500 rpm with good airflow and no noise. Looks awesome

The fans arrived on time and were easy to install. The difference it has made to our living room is incredible. Total silence. You can only hear the air moving out of the computer if you lean close. Would highly recomend these fans to anyone upgrading or doing a rebuild, you wont regret it.

The media could not be loaded.  I was afraid these fans will be obnoxiously loud.I was proven wrong.In the video attached you can see a comparison of 2x 80 fans and a 92 mm intake plus a noctua LP in 100% use Vs my (current) case with 4 fans in idle. I would say, even though they whine constantly under heavy load (not recommended btw) they do their jobFrom me 5/5-easy to install-flush (as long as you use the provided screws)-work straight away with my pwm splitter (they could have added a 3 pin like artic did, but I'm happy to sacrifice connectivity for quality)-compared to my stock hp/foxconn 80 fan they are way more quiet and do a better job as well-it's the perfect companion for an htpc case especially if you plan to a GPUless build; I bet I would (be) even more quiet without a gpu and/or heavy load-for 8 quid is so worth it; I've tried everything from 120 to 92 mm, none are as effective as these fansBut don't just take my work for it...Try it yourself...to (be) quiet

Delivered well protected. Simple to install.

Work as expected, the name is spot on. I wound recommend these to anyone.I personally used these to replace some noisy stock fans that came with a Raspberry Pi cluster case I had purchased. I hear nothing now. :)

j'ai remplacé un ventilateur de PSU très bruyant par celui-ci et depuis je suis zen

I bought four of these for use in a server chassis. I can barely hear the server running. The fans installed quickly taking me only a few minutes to install all four fans. Great product!

I got these two fans to install on my rig tied with a 280mm AIO. These fans are worth the price in noise level and amount of air it moves through. I'm not going to sit here and say they are the top fans. There are others, but these are consistent in noise level and moving air, and last a lifetime in my honest opinion. You can not go wrong with these fans ever.

Comparing these to my cougars I'm very happy with them.
