I have exactly the same version of HPB 120, without the controller, which was later added to the packages. I am very satisfied with the flow, sound, ease of installation, which were greatly helped by the cables and the light adjustment mechanism. The mechanism has a magnet so you can attach it to the chassis of your case.

The only downside I find is that the LEDs of the cougar turret (case) that I have, have twice the digits and the difference between them is slightly visible, because I have installed one in the front (the case has two more in the front). But the important thing is that the factory colors are exactly the same tone and they are all uniform inside.

Amazing and beautiful. The lighting simply enhances the appearance of the case. Regarding a friend's comment that the remote control only works if your motherboard provides an aRGB header, this is not true. Whether the motherboard has an aRGB header or just RGB, it doesn't matter. The remote control always works. And the unique and beautiful colors and patterns can be changed through the control. You can simply choose whether you want to change colors and patterns via (aura, icue, etc.) or through the remote control. Also, if the motherboard has aRGB, someone will be able to see some additional unique lighting effects. As for the noise and cooling they provide, I am very satisfied. They are quiet while providing very good cooling for the machine. I should note that I am not a gamer and I do not overclock, so I do not have an opinion on its performance in extreme conditions in terms of noise and cooling capability.

Well. Since I was searching everywhere for how these fans are, I decided to try them with the Cooling Kit.
First of all, they are a real gem inside the box. Really. I bought them to go along with the case (due to the same brand - Cougar Panzer Max)
They are not too bright, but not too dark either. They are just right. Silent (And I have installed all three) with the DVD Player making more noise. As for cooling issues, they have 12 cm fans that make no noise at all and they are beautiful. I only saw a 1-2 degree difference in the motherboard's temperature (With Speccy.) These ones seem the same as Stock Fans to me, just beautiful. (That's what I was looking for. A gem inside the tower.) I will also include a link to show how they look at the end of the review.
So here we go.

Pros:
● Beautiful LED.
● Silent at 1200 RPM.
● Remote control for colors (Look below).
● Box to connect up to 8 fans (and 2 LED strips).

!!CAUTION!!
The remote control requires an Addressable RGB Reader to work, something that my motherboard DID NOT have, but it didn't bother me since the LEDs from the default settings are still beautiful. The motherboard I have is Asus Rog Strix B-350, which has 2 RGB Readers, not Addressable RGB.

Cons:
● Overpriced from a monopoly store.
● Not better than Stock Fans.

Internationally, they go for $50, in Greece we go for €62 (plus shipping, of course).

All in all, it is a beautiful gem inside the case, if you have a Tempered Glass. For me, it was worth the money and more.

From me, 5/5.

-!EDIT!- 13/01/2020
Seven months later, I decided to come back and update on what's happening exactly...
Firstly, the fans are still holding up. Nothing has changed since the first day.
Secondly, I still haven't upgraded to change the patterns and colors of the fans, but it doesn't bother me.
It is a gem inside my tower, no matter how you look at it.
From what I see, another store started selling the fans.

The core box presented a problem, resulting in none of the fans turning on (I am referring to the LEDs)
