Pros: - High static pressure or focused flow :) - quiet at 70% power and below - solid build quality - if you don't like the orange vibration pads you can take them off and then these fans are all black :) - like with every noctua fan, braided black cable is clean and quality - PWM control is on point.

Cons: - At full speed these fans are loud and they should be so not really a con just being honest and objective.

Overall Review: So this fan in particular might not be for everyone. These are industrial versions. Noise is not as big of an consideration as airflow output, power input, etc.. All 2000 rpm fans and higher are going to be loud especially at 120 mm. With that being said, I have three of these running off a hub connected to my cpu fan header. Push/pull on my 212 evo and the rear 120mm exhaust fan all in line if you know what I mean. I controll all three of these fans together and they run at 50 % power which is the lowest i can set them at and my Fx 8350 4.0 g ocd to 4.4 g never goes above 54*c at load and the fans never have to increase power :) I have another 3 noctua fans that are hubed and running in line also 2 140mm intake and top mount 140mm exhaust. those are set to 60% which is why my cpu cooler setup never has to ramp speed. Anyways, if you are looking for a good fan pick noctua, if you don't care if its a good fan, go with any other company. lol. read the specs, know what your buying. These fans are excellent at all applications but really shine as cooler, and radiator fans. Noctuas pwm and volt control is so on point that the 3 fans never run more than 5rpm +/- from each other literally which is hard to find if you know fans. These fans have access to the bearing as well. I have spent over 130$ in the last 3 weeks on fans alone for my newest build all noctua and for gaming air cooled it dosen't get better.

Pros: these fans move air, are inexpensive, and convenient for very light applications. If your rig is not built for gaming, then these should do for case fans. At full 1200 rpm they are not to noisy. These are good for filling empty fan slots, and connecting them to the power source running at full power. Temporary replacements.

Cons: cheap fan construction, rainbow wires

Overall Review: These are just a cheap safety net. Its good to have some cheap fans handy just in case one of my 6 noctuas die on me. There is not much bad to say about these fans. Objectively speaking. These are not high airflow or static pressure. they are rated at 44 cfm at 1200 rpms . This is a decent fan because it performs as advertised, and at this price cheap construction can be expected. Don't order these fans expecting performance that will tickle your toes, go with noctuas for that.

Pros: - bright, nice settings.

Cons: - cheap build of power hub, no biggie

Overall Review: for the price it is awesome. one of these tucked in the right spot is all you need. I platic diped the power control box red and put an amd crest on it and double sided taped it to the bottom of my case. I have a windowed case and it looks like it belongs. good modding option on the cheap, allows you to get creative.

Pros: - fast response! hands down - tons of settings, gamer profiles and such.

Cons: - I knew what I was purchasing so not to disappointed here - just nit picking but, maybe a height adjustment as in up and down would of been nice.

Overall Review: worth the money. I originally ordered an asus 23" monitor for more money but new egg was out of stock of that model, picked this due to matching color sceme and amd freesync. sooooo. happy with it.

Pros: - does what it says

Cons: - a little stiff, less with the "Y" splitters but not a deal breaker.

Overall Review: - if you need this then get silverstone. Rpm feed back is reported off the four pin header, the other 2 are 3 pin that match voltage. Know what to expect from products and you won't be writting bad reviews.. I use this to run 3 noctua 2000rpm industrial. 2 on hyper 212 evo and a 3rd right inline as exhaust on rear case if you are in the know. If your looking at this review then you know enough about computers to know what it does. This quality is worth the price. pull the trigger

Pros: - does what it says.

Cons: - supplied velcro is junk - blue led

Overall Review: -great product overall. runs 6 noctuas for me. connect it to cpu header for best results unless you have other fan headers with micro adjustments. cpu header will allow all connect fans to ramp at cpu temp rising. It would be awesome if the light color could be changed, but if that is all I'm complaining about then you probably should just quit reading the review and buy it already.
