Very good fans, but very expensive nonetheless. I have 3 in my 760t and at around 1000 RPM you can only hear the air moving fantastically and they look great too. The rating goes down to 3 stars because Corsair doesn't know what shade of white they want to put on their fans. One time it's regular white, the other it turns yellowish, and another time it's almost yellow. This is unacceptable! Literally awful quality when it comes to the "white" issue!

Good build quality once again from Corsair. The packaging is simple and it should be noted that it does not include screws. The lighting is excellent with the 4 LEDs in the center of the fan. When the fan exceeds 1300-1500 RPM, it can be quite loud but it moves a tremendous amount of air.
I already have 2 as intake fans in my case and if they continue to work without any problems over time, I will definitely get a third one for exhaust.
The only downside for me is the high price. It seems to me that the current price of 25-30 euros on Scroutz is not representative of the product. However, I think that 20 euros would be a good price.

Excellent and very beautiful fan! I have installed 2 on the H150i PRO RGB and it cools the PC exceptionally while not making any noise!

I have installed 2 ML140 as intake fans and I can say that I am more than satisfied. Connected to a fan controller with maximum speed at 70%, their performance is excellent. Almost silent, with incredible airflow and a fairly intense illumination. Maximum motherboard temperature measured with HWiNFO ranges from 29-32 degrees idle to 43-45 degrees under load. The build quality is very good, it is not cheap plastic, they are worth their money and more. A big plus is that they do not have bearings and the rotation is magnetic. Noise will be heard at 100% speed, but it is logical due to the huge airflow. Also, a big plus is the 5-year warranty.

The best thing I have installed on my PC. I saw an 8-degree difference in the temperature of my Corsair 110i cooler. Quite silent and easy to install. It's worth the money and more.
