The only problem is that its RGB interface is not compatible with all motherboards, but you can use the alternative wiring it has and everything is fine. Overall, it's worth it.

For €8 each, they're just fine. I have the box next to me and they barely make a sound. I connected them with 3pin to the motherboard. I wouldn't say they're white, but a nice light blue. I highly recommend them.

I connected the fan with a molex for full power. The sound is not so quiet, but it is a fan so it will be heard at least a little. The sound is satisfactory so far. Also, the white model is not completely white, it leans towards blue

I have them for 5 years now, they do their job very well and they are also very beautiful. I run them at 1000rpm and they make a good noise, but if you lower them to 700rpm they are completely silent and still do their job perfectly! Worth it!

I put it in a case with not the best airflow, and luckily it did the job. The sound, on the other hand, is like a turbine. One moment I put it on, the next moment I take it off. Especially for me, who have the case at the height of your chair, it unfortunately hurts the ears.

I've had these fans three years now. No issues whatsoever, they still perform as they should and the LEDs have not lost their quality. It's a great bundle.

After 2-3 years, one out of the 4 started to sound like a tractor. On the other hand, they cost 5 euros. You get what you pay for! Otherwise, they are fantastic. I have had the Thermaltake ones for almost 4 years and I have 6 of them, and they are all like new. (Of course, I paid 50-55 euros for that trio.)

After 6 months, while I had it consistently in red, every time I turn on the PC, the color changes and the controller doesn't work at all. It now only turns on in green and after 2-3 hours it becomes blue, and only if you close the PC and open it again it becomes green. It's tragic.

Combined with a cooler from the same company, the result is excellent and beautiful.

The most value for money. 2 sets of 3 were bought with a 5-month difference. If the case has good airflow, they don't need many rotations to do their job, so they are quiet. They were installed in a Kolink Stronghold case. They have a control in the packaging to adjust them (color and speed), otherwise you just connect them without it. You download the program of each motherboard and adjust them easily from there.

P.S. The Kolink Stronghold doesn't easily fit 3 120mm fans in the front.

Okay, what can I say, at 35 it's the absolute value for money, easy installation with the provided instructions, the length of the cables is fine, the hub doesn't have good adhesive at all, but with double-sided tape it's fine to hide it at the back. You download the corresponding software, for me it's MSI Center, you set the scenarios you want, fan speed.

It is one of the quietest fans, at full speed (1500rpm) it is silent, the graphics card reaches a maximum temperature of 64C in the summer, while in the winter it reaches a maximum of 54C. If you put a case with a mesh panel in front, it will have even better temperatures. I highly recommend it

I would give it 4.5 stars but it's not possible. Nice construction and easy installation, although the screws were not tight enough. It makes noise at the ends, but it is silent and quiet in silent and normal modes. The negative aspect is that the lighting is not exclusively white but gradient. In silent mode, it is red, in normal mode it is yellowish-white, and in full speed it is white. The lighting is quite intense and beautiful.

I have used it for external hard drives in a makeshift box and I am completely satisfied!

The colors have nothing to do with the photo! It is the most beautiful blue I have ever seen! Get it!

I bought 4, the white ones according to how fast they spin, they also have a more intense lighting, they make a little more noise than I would like, but nothing crazy, the lighting at around 50% speed is fantastic, below 40% it turns red to white or very warm white. However, the airflow is very good, it passes enough air at around 50-60% and you will be completely satisfied if you can live with a little more noise.

Beautiful, quiet, and efficient. Mistake that I only bought one. Pwm and 4 pin connection to increase speed according to the temperature of the case

Simply excellent. I have bought 4 so far and they do make noise, but personally, I mainly use headphones and that doesn't bother me. I suggest connecting them with molex for better performance and more intense color. The best value for money I have seen. Get as many as you can.

I have 3 fans in my possession... I will start by saying that they cost 5.5 euros, so don't expect them all to be yours... Nevertheless, we are talking about a very satisfactory product, with very good construction quality, strong lighting (so much so that I have them at the back and they illuminate the inside of the case well), powerful, greatly assisting the air flow... The only complaint I have is that I would like them to be quieter since I have the PC in the office... Nothing crazy, but it would be a plus... Therefore, if you are looking for an economical solution that will illuminate the inside of your case and have okay airflow, then it is definitely a good investment

It has good and nice red lighting for its cost and two connection options, 3 pin and molex. I have installed one connected to the motherboard's only port and one in the front which I have connected to the PSU's molex. The one in the back operates at 750 rpm, which is automatically adjusted by the motherboard based on temperature, while the one in the front runs at full speed due to direct power supply from the PSU at 1400 rpm, which means a lot of noise and headache if you have it next to you.

"To help you out"
Personally, I will get a hub because I want to connect two more directly and with that, I will avoid the noise as they will all be connected to the motherboard (via the hub).

"Update"
By setting their speed through the BIOS, I made them quiet and efficient.

Whoever says that they make noise, it would be good to adjust them to the lowest settings. They are not audible at all on the low setting. When you increase the settings, yes. For their price, they are very good. I put them in an MSI B450 GAMING PLUS MAX and they work perfectly with their RGB "lights" settings

Great value for money, at 5.50€ it does what it promises, excellent lighting and satisfactory airflow (I have 3 in the front), noise at full speed, which can be solved if there is a fan controller, and it gets 5 stars because other fans that cost 10 and 15€ perform the same in terms of lighting and noise.

I have 3 Red ones and one Blue.

The maximum speed I see when I set them to 100% is 1480.

Up to 1000-1100 RPM it is quiet, but above that, it is audible (I don't have it with anti-vibration pads).

In 4 out of the 5 photos, it seems like it has anti-vibration pads, but it doesn't. In the photo where the box is, it is also evident that it doesn't have pads if you observe it.

For cooling, it is good for the price, but average overall.

The intensity of the LED adjusts according to the fan speed when it is connected to a 3-pin connector, but when connected to a molex, it is at full brightness and power.

I don't mind it for the purpose I need them for.

The packaging also includes Black screws.

I can't understand what others liked about it... It looks nice but it makes way too much noise, I couldn't even watch a movie. The cooling is so-so, it does something but I can't imagine that it doesn't have a program to adjust the speed if you put it on silent mode with the fan expert program from Asus that I tried, they stop and start on their own when it reaches 50 degrees and they go full blast and then stop again. Maybe there is a program and I didn't find it, but it's not even on the website. They synchronize with aura with msi and ashrock but only that. Excessive noise, they're not worth the money, I'm thinking of getting rid of them

Guys are really good in gold, also gives a hub to connect them perfectly, they don't make any noise at all, 100% value for money
