Replacing all of my Corsair SP and AX fans with the ML fans

I hope they are worth the price. Bought 4 x 120 and 3 x 140 blue LED. Installing them now.

Let us know how well they work. Been meaning to get a few for a new build.

Got them installed. They are loud at full speed. Thankfully, I can control them with the motherboard PWM management and my Aerocool fan controller.

@AdamK47 They look great. And that is one nice rig you have.

I've owned these fans for almost a week and have learned a few things based off of my experience with them. The first thing I noticed was that these fans do not like voltage control. They work much better on PWM control. I had 4 of the fans on an Aerocool DC fan controller and 3 of them on PWM control through my motherboard. The DC fan controller goes in 4 steps. On, 25%, 50%, and 100%. 100% gets the fans at full speed. That works well, but it's very noisy and not practical for everyday use. The 50% setting is not enough to drive the ML bearing. It would only spin the fan at between 400 RPM and 500 RPM, which is the lowest speed for these fans. I have since switched all of the fans over to the PWM connectors on my motherboard and removed the DC fan controller. You can get any speed you want out of the fans with PWM in relation to system temps.

Did some more tweaking to the fan configuration yesterday. Reversed the three 120mm radiator fans so that they are blowing down. It seems to help out. I also tweaked the PWM settings for the best balance between noise and cooling. I'm totally happy with the fans now.
