Pros: nice fan, good purple color. works great.

Cons: none

Overall Review: recommend this fan.

Pros: Nice deep purple, moved plenty of air and isnt too loud while doing it. I'd totally buy these again!

Cons: Some times it's confusing to mix up the AF and SP AF : Air Flow, good for CASE cooling within a UNRESTRICTED space SP: Static Pressure, Great for radiators, cpu coolers, places where it has to push the air through something.

Overall Review: I hold zero regrets getting these, other than my wife deciding she needed them too and buying a whole bunch for her PC.

Pros: iz good

Cons: none

Pros: Purple - It's the reason you're here Quite at low RPM

Cons: DC Control of the fan causes it to whine at around 70-80% voltage (RPM). PWM control would solve this problem.

Overall Review: Given how few choices there are for purple LED Fans, this one is the clear top pick, just wish it had PWM control to allow for better speed control.

Pros: -Silent, even on highest settings. -Moves a lot of air.

Cons: -Expensive compared to other similar 140MM LED fans. Not really a con if they last, in my opinion.

Overall Review: I bought two of these for top mounted exhaust fans in my NZXT 440 to match the overall red & black theme of my build. Was hesitant at first because of the price point, but they look excellent and perform exactly as advertised so I'm pleased overall.

Pros: Quiet with great air flow.

Cons: LED's not as bright as I would like.

Overall Review: LED's weren't the brightest but they do have a deep red in color. Accents the case nicely.

Pros: Lovely and gorgeous fans, excelent airflow. Could never ask for a better fan

Cons: bad part is, the led already started to flicker and fade. (bottom right) and well. Other than that it's a great fan. Not like the light bothers my airflow. Just is a killer on the eye.

Overall Review: I wouldn't not recommend this fan only because of the faulty LED's they're still a great fan and I probably could've just got a bad one..

Pros: These work great, move some good air and look cool too

Cons: not 4pin but the asus Z97-Pro handles them without a hitch and keeps em at around 500-550 and I cant hear them in the front of the Carbide Air 540, put one in the back also

Overall Review: Quiet, Moves air and Looks Great.
