AeroCool Shark 140mm Red Cooling Fan EN55475

This fan moves a lot of air, but it’s best mounted vertically like I’ve had on my mining rigs and they’ve worked wonderfully for almost a year. This 140mm was mounted horizontally at the ceiling of my computer case, and after a couple months it would rattle and I’d tap it and it’d stop. Now after about 8-9 month it is SUPER loud and there’s no adjusting it that will fix.In summary: Works great and moves lots of air, but develop anoying rattle when mounted horizontal.

Like the color, aren't to noisy until you reach the 75/80% level, leave around 40/555 and are pretty quite, like the rubber screws, interesting but not to effective. I want to say the screws it came with didn't work. Seems to move decent air. Got them on sale. The leds look nice, also pending speed the lights adjust which is cool to me (0 off 100 bright) overall I like them

Very quiet but move a lot of air. Great performance so far.Worth noting: If the fan will be very visible from the outside of the case, the blades look pink in daylight do to the transparency. When lit up in the dark, they appear much more red than typical clear blades. For my case, they are perfect as you only see them when they are lit up.

I really like these these fans, I got three of them. So far they are all working great and installing them wasn't much of a hassle. Not too loud and they look amazing.

These fans really move alot of air. Added them to the RV refrigerator back top vent to exhaust heated air. They turn on automatically with a thermostat mounted on the pipe between the fins. They are also very quiet while operating. Hopefully they will last.

Moves a vast amount of air and the noise does not bother me since these fans keep my PC components running cool for sure! The fan frames are not as rigid as some others that I have used but these fans work as advertised.

This fan is LOUD! If you want a quiet fan look elsewhere, but if you want a good looking fan, and don't care about the decibel level, this is the fan for you.

These are great fans... move a lot of air. No vibration, all LED's work, great cabling / sleeving... just a top quality fan! I have 9 of them.... I just wish that they had more static pressure, so I could use them as radiator fans.

Pairing this with an Red shark fan, I fitted them inside my Aero-cool GT-A case and they do deliver quite exceptional results when needing to regulate air flow at high temperature loads.- Unboxing -The fan comes in a happy shark designed plastic box in which you can see the fan beautifully presented.Now, I'd suggest opening the box at this point so that the illustrated shark does not become more eager to eating you alive.Along with the fan, they provide you with a Voltage Reduction Cable (silent mode) which allows the fan to run at a reduced voltage and an RPM of 800, with a tolerance of +-10%They include a Molex Connector - 3+4 pin connectorThey give you a Anti-Rubber screw which if you use, don't blame me if you can't get them out, they work but are RIDICULOUS.- Build Quality & Functionality -The fan itself has aerodynamically designed 'fins' which seem to work very well and suck air through the fans excellently.They have weight to them and the fins feel pleasant like they're soft full of gel.Since I've paired this with a different coloured one, they perform perfectly fine but the only let down is the bloody noise.I have a variable wheel on the front of my case which allows me to crank up how much power I want to let through the fan, the slightest of power will send these fans spinning at a fast rate but will produce noise that can really start to annoy you.The LED's are not quite as bright as my other shark fan and if you do want to get sleep at night, I'd suggest turning the fans off. They're pretty useful as a night light as well as being fans.- Overall -If you need fans that perform well and has great air flow, these will do the job. At the cost of a noisy fan at moderate-high speeds

Got it briefly in my hand as I ordered it, but sent it back when noticed I got one with the wrong plug. Didnt mount it in my chassis but when connected to mainboard out off curiosity, was thrown off by its loud whining noise. It also doesnt start before 600rpm and at that its already loud. It may have 15 blades but its a gimmick and noise creator as there are many others with higher CFM at lower speeds.beside - it feels cheap and plastic-ky.althought, has to admit - LEDs are nice and evenly spread, looks better than other fans with LEDs I have seen.

Again thanks for the super fast delivery for Amazon PrimeI bought 1 x 14 cm and 2 x 12 cm of this fan and it's fit very well in my Aerocool Strike-X case, It Came very well packaged , and everything what you need for a system fan is included in the box (3 pin to 4 pin converter cable ,anti-vibration rubber screw, regular screws ,even a voltage reduction cable ) You will need the voltage reduction cable because on full power it's very loud , but we all k'now every fan making more noise on full speed even if they advertising as "quiet fan" ,and if you ask it ,it does the job even on 800 RPM and you can't hear it on that speed.I'm gonna buy more 2 of this soon , and I recommend it for everyone.

I got 3 of these fans for my lian li pc7fn case, they do their job well, theyre not too noisy and perform great with bright red leds and transparent smoked black frames they look the part too.

Great air flow and nice bright LED's. Quite silent too.5 stars as its value for money. You get an excellent piece of equipment with good ratings (CFM)
