CorsairPremium Magnetic Levitation RGB LED 140mm CO-9050078-WW

yeah It's not cheap but considering it will probably last forever as there no bearing to wear off.the lighting effect are prefect and can be customized to your desirevery quite I run all 6 of them @ 1300 RPM and I can barely hear them (they max out @1600 RPM)take long time to cable manage them it's a nightmarehighly recommended

It is a good quality product, however the generic statement "Expansion Kit: This product is intended as an expansion of the ML140 PRO RGB LED 2 fan kit with Lighting Node PRO" found in the product description is not really clear nor accurate.Not accurate because these FANs can be used as an extension of other Corsair kits too, not just the ML 140 dual kit. Not clear (The bad part) because FANs do work without a Corsair hub, however the LED lights will not work without it. This should be clearly and precisely explained in the product description, and the current generic inaccurate statement should be removed.

i order the dual pack but i get the only on single pack

Hacen mucho ruido, pero avientan mucho aire, asegura de configurarlos de tal manera que solo se enciendan cuando realmente se necesitan, de verdad hacen mucho ruido, yo como tengo la pc al lado del monitor me resulta molesto el ruido, asi que tuve que apagarlos y poner que se activen solo cuando la temperatura del pc sube tales grados. Pero si quieres ventilacion, estos son los que mas ventilan en el mercado, de los que encontre. como 73 de flujo de aire tienen.

My subjective experience is that these ML120 fans provide ~30% higher rpm at the same sound volume as the SP120 fans they replaced (also by Corsair). My SP120's had a 50% failure rate. While still functioning, 2 of the hub stickers were blistered and bearing noise was noticeable at best and blaring at worst, requiring running at 1000rpm to keep them quiet. The ML120s so far are quieter and more powerful, while costing near what it would take for replacement SP120's. $22 each in my case (on sale/EOL for this version i think) .Buying computer fans is such an annoying experience because the differences between competing brands are opaque beyond super cheap = poor quality. I settled on these fans because they were one of the only offerings to claim an actually different bearing technology at a price not low enough to have "poor" longevity. Initially they are in fact a better product than the SP120 by the same company. Who knows though.

super quiet and great airflow!!

Es un muy bien ventilador para radiador, lo compre para hacer push pull en mi corsair h150i elite capellix, la única diferencia con los ventiladores de esa aio es el RGB pero tiene el mismo desempeño que los ventiladores de la elite capellix

I ordered 4 of the ML140 Pro 140mm RGB LED fans. I received 4 ML120 120mm RED LED fans. I returned the package for replacement with the correct items. The second shipment arrived and had the same ML120 120mm RED LED fans. I checked the Amazon barcode label on each fan and confirmed they have the incorrect label, as they list them as the ML140 RGB LED Fans. Spoke with an Amazon agent and all they could provide was processing the return. So, I have ordered 4 of the ML140 Pro RGB LED fans from another source.I rate the fans 5 stars, as they are hard to beat in airflow and low noise level . There should be a selection provided for the shipper/seller to rate their service!
