Be Quiet! Cooling Fan Bl067

Brought one cheap PC case, which have 4 cooling fans (1back -3 pin, 3 front, with RGB LEDs).The problem with original fans:- the back one have 3 pins (my motherboard have 4 pins -PWM).- the front fans are running only at full speed, very noisy. Not interested at all about LEDs light (unwanted).So, I ordered 4x 120mm fans BL070 as replacement.- PWM speed control (my motherboard having 4x chassis fan connectors, 4 pin-PWM)- The fans running sooo quiet!- At full speed (2200...2300RPM), the noise is just OK, not disturbing too much (compared with old no-name fans).- 2 options for mounting: hard plastic pieces (for screw mounting), or rubber pieces (for push-pin mounting).In the box: the fan, 4 hard plastic corners (+screws) , 4 soft rubber corners (+ push-pins/washer).Connection cable is approx. 40cm, long enough to connect at opposite side motherboard connector.From manufacturer datasheet, lifespan @25 Celsius = 300k hours!! (over 34 years?)My system:65W TDP processor (i7-10700) + older closed loop SEIDON Cooler Master (120mm radiator).Motherboard is Gigabyte 490UD, with 1 CPU fan connector and 4 system fans, all 4 pin, PWM.During tests, with all 8 cores at 100% load, pump (CPU_FAN) is running at full speed, continuously.The 120mm radiator fan kick-in at approx. 2200RPM and keep processor at approx. 72 deg. Celsius.Can hear air blowing thru radiator, but not disturbing.During normal use (watching movies, Youtube, etc), temperature is lowered at 41..42 celsius, fan not audible (set at around 1300 RPM).Very happy with those fans.

This is the silent wings 3 fan. Amazing fan with very good performance and very low noise level -- as compared to my old NZXT that came with my IO this is like 10000% times better - - highly recommended if you are having issues with noise level

المراوح هادئه جدا وتبريدها ممتاز. احد الزواية كان فيها خطأ مصنعي وما كنت اقدر اركبها.. فركبت الزاوية الي تحتاج مسمار.

I looked at a lot of fans and opted for the high speed 140mm silent wings 3 fans from be quiet!The fans come with two types of corner attachments - plastic and anti vibration. The instructions are quite simple, but the fans are too notch. Very quiet when not being pushed at full speed.They're well made and easy to install too. Very happy.

Addendum Circa 2021/22:After ~3 years one of 140mm fans developed bad imbalance/scraping noise. I think it was actually badly balanced out of factory (I've noticed rotor visible beating), which gradually got worse with time.Initially I've tried to go through beQuiet support which previous was great for me, but they ended to be not so great now - they wanted me to ship fan internationally to Germany (at my expense!) to simply "inspect" the fan and then decide whether it qualifies for replacement. I had to raise claim and obtain replacement through Amazon instead (after some back&forth proving that beQuiet actually advertised 5 year warranty on SilentWings 3).Deducting a star due to this, and now back to original review.These fans I consider the best "all-around"/universal fans available. That mean, they could be used both in airflow and static pressure applications, and have best airflow/noise ratio.Noctua fans have (very slightly) better raw performance, but they are somewhat more noisy - at least in "perceptual" sense. Noctua fans (especially in latest China-made revision) have almost smooth blades and very sharp-edged plain square hub spokes - this creates pronounced "boop tone" at certain resonant RPMs, which (at least for me) are a lot more annoying than white noise of rushing air.While Silent Wings fans have very "ridged" structure on their blades - this creates more air turbulence and while it technically makes fan to lose some small amount of performance, it also makes noise spectrum almost all white noise, which is a lot easier for our brain to filter out and stop noticing even at moderately high fan RPM. Also Silent Wings 3 fans have aerodynamic-streamlined hub spokes, removing "impeller passing noise" (caused by blades pass the hub spoke at exact frequency).The only downside that SilentWings 3 have somewhat noisy PWM circuitry - you get "coil whine" noise, especially noticeable at low RPM when rest of fan is silent. At the contrast, Noctua fans have SCD PWM driver which completely silent - sadly seems that beQuiet still haven't implemented such tech. Also PWM control lacks smoothing - fan tries to change rotation speed instantly which causes other kind of "rumble" noises on abrupt RPM changes (e.g. when temperature spikes).Note that electronics noise disappears if you control fan by voltage. The only downside of voltage control I see that lowest rotation speed becomes ~450RPM while in PWM mode its ~200RPM. But I'd say it does not really matter - since fan is already 100% silent at 450RPM. So I'd recommend getting voltage control model and save money - but PWM model is still ok since it supports both control modes.Note that I've now tested 8 (6x 120mm and 2x 140mm) fans and they all exhibit same characteristics.Addendum circa Jan 2020:After changing to X570 Gigabyte Aorus Master motherboard (Previous was Asus Prime Z270-A), I don't notice PWM noise from fans anymore. So it might be motherboard dependent and you might or might not get it. Always worth trying PWM first to see if it suits you (it also looks like the price on PWM model often actually less then on 3-pin one).Another thing worth adding that these fans actually very electrically efficient - according to beQuiet own official spec sheet, single 120mm fan draws only 120mA current. This means you can drive even 4x fans from same standard 1A motherboard header no problem - no need for complex splitters with external power.

A few years ago I purchased a be quiet PSU and was extremely pleased with it so when looking at fans for my cpu radiator I went for this one. Again be quiet have excelled. I can't, yes can't hear this fan at all, even at load. I have to check system monitor to see if it is on.It is as it says very, very, very quiet. This is due to the fan blade design, the blades aren't flat which allows air passing through to be broken up, Gigabyte use the same technology on their gpu coolers. Not giving a tech. lesson but the idea comes from bird's of prey's wings which splay feathers at the wing's end to break up air and thus hunt silently.Excellent product, a little pricey but hey - silence is golden.

Getting a consistent fan that's quiet at all rpms, without ticking or other noises is very difficult. The Silent Wings 3 is one of those great fans. I've got a few and they're all very good with no annoying ticking or buzzing. At extremely low rpms they can grind/tick, but that's almost right at stall speed. For this reason you're best using proper fan control, rather than let software auto-control where the software can sometimes hang around that stall speed. The reason for this is these fans run at a lower rpm so in 'quiet' mode the power from the auto-control can be a little too low.Bundled with the fan are two sets of rubber insulators. One for screws, and one for completely isolating the fan with rubber. You'll be familiar with this if you've used Noctua fans. However, unlike Noctua where the rubber 'pin' is super annoying to use - it's super easy with the Silent Wings fans.

I have so far refrained from writing this review as I deemed it only fair for BeQuiet to have a chance to resolve the issues I've had. Unfortunately the issue is still not resolved, therefore I'm writing this review just to warn others of the potential issues that I've encountered.The first fan (top of the case) is the Silent Wings 3 (non high-speed) version which I purchased first. It works an absolute dream and is literally silent even at full speed, although the rpm is only 1000 I believe.Being so happy with this purchase I decided to purchase another for the back of my case, this time a 120mm high-speed version as I figured that extra push would help the cooling in my case. To say they're different is an understatement. The high-speed version is ridiculously loud at high-loads, making me question whether there was an issue with the fan as it's absurd to have it branded as 'BeQuiet' otherwise.I contacted BeQuiet online and their customer support has been far from amazing. I was told if I send them a picture of the fan dismantled then they will send me another one, to which I replied that doesn't really help my issue as I need my PC to be operating for work and I no longer have the old fan to replace it with.So in conclusion, I still don't know whether this fan is faulty or if this version is just horrendous in comparison with the original purchase.
