I replaced the fan of my Corsair TX 850 power supply from 2009, which sounded like a turbine, with this one and connected it to my motherboard for power, running it at 1600 RPM which is its maximum. It is set from the computer's BIOS for safety at its maximum power. Even at 1600 RPM, it is barely audible. The replacement was relatively easy if someone wants to attempt it on this particular power supply, just be careful not to touch the circuit because even when switched off, the input capacitors have high voltage. The maximum power I draw is 350 watts on an i5 6500 system with an Nvidia 3050 graphics card, so I'm not worried about overheating. I will update if anything happens in the future for a re-evaluation.

Silent and efficient fans. Excellent for their price. My only complaint is the screws, which were a nightmare to tighten.

Excellent fan, with good airflow and silent operation. Very convenient that for more than one, the cables connect to each other so no splitter is needed in the motherboard socket.

Even the packaging is simple and practical, it contains the 4 screws needed

The Arctic P14 PWM PST is excellent for the following reasons:
1. **Silent Operation**: Provides quiet operation even at high speeds.
2. **High Airflow**: Ensures effective cooling of the system.
3. **Easy Installation**: Simplifies the installation process in the computer.

Highly recommended for demanding systems.

Quiet fan with enough pressure and air volume is vfm, of course it is simple and a bit difficult to clean the dust from its blades. (with a paintbrush you can manage it, of course).

I put 2 out of 5 in a large case for the 5950x and they work completely silently. The other 3 I placed in the case with the Threadripper 3960X and they also do an amazing job without noise.

Obviously, you can set how they will operate from the BIOS, but my motherboards are Asus and with Armory Crate and All Suite I can adjust all the fans of the computer there without going into the BIOS.

Also, the daisy-chain feature they have is perfect; you connect them to each other and with just one connection to the motherboard, you can have more than one fan. Their power consumption is negligible, so don't be afraid to connect them this way.

I'm thinking of getting another 5 and placing them in a few spots where I can, as it's better to have several fans running at low RPM than to have fewer and have them running to cool the case.

Honest fan for its price.
Over 1300 RPM, PWM about 75%, it is not silent and can be quite audible. However, the cooling and airflow it provides, even below 1300 RPM, exceed expectations given its low price.
I bought 2 for the case intake and I am completely satisfied so far. I have them running at exactly 1200 RPM, PWM 67%, which I consider to be the best performance/noise point.
The only thing I didn't like is the relatively short cable. It is 40 centimeters long and unfortunately, it doesn't reach behind the motherboard to hide it. Would the world end if they made it 10 centimeters longer?

Relatively quiet fans, but you need to pay attention to their usage, as stated in the specs, they are static pressure optimized, meaning they are designed to push air at close distances in difficult areas, rather than expelling hot air out of the case. After testing them with a 360mm radiator, I have experienced worse temperatures in gaming scenarios, with an average increase of 4 degrees Celsius on the processor compared to the Noctua AF14 chromax in the exact same setup. Additionally, there was a decrease of 2 degrees Celsius on the memory and NVMe drives, tested in the same positions and conditions. Overall, considering their price, they are quite good and no one will have any complaints.

Quiet at 1200-1300 rpm (above 1200, you start to notice the fans)
They reduced the GPU temperature by about 10 degrees, generally the system dropped by 3-5 degrees, a big advantage is that you can connect some of them together to easily control their speed or if the motherboard doesn't have many ports

I got them to replace the Fractal Design 140mm fans that originally came with my case.
Their price is great, considering that we're talking about fans that perform very well, are relatively quiet (below 60%), and even at 100% they're not excessively noisy. They are clearly better than most fans I have tried, and almost on par with the much more expensive Noctua NF-A140.
A great value for money product!

The best economic 140mm fans. They have a 4-pin PWM connection for better control, but also PST for interconnecting. Ideal for motherboards with few case fan slots. As a set of five, they are cheaper than buying each fan separately. They come in a box, all together with the corresponding screws

Excellent construction. I bought 2 and they reduced the computer's temperature by 10-12 degrees while playing heavy games. Completely silent, easy to use instructions, and the ability to daisy-chain them together, so they don't take up many slots.

A star only loses for their noise, I lowered the speeds quite a bit from the bios but because there are five untamed monsters inside the deepcool eshield, it makes a little noise.
Their cable management is difficult but it happened once and it won't happen again.
It maintains the airflow just fine and the case is a permanent refrigerator.
Good fans for now, we'll see what fish they catch in the summer.

It lowered the temperature for me in every game I play by about 3-7 degrees on the CPU and GPU.
Apex: from 71 to 65-68
Cod Warzone: from 65 to 60
Gta V: from 82 to 70-80 and many other games

Unbelievable. It made the refrigerator. With a speed control program, it is quiet. But even at full volume, it is not very loud. And the fact that it is PST helps if you don't have a splitter. I recommend it

Two Meshify C cases were purchased. There is a significant difference in temperatures, especially in the memory where I saw up to 12c lower. At full rpm, they make a lot of noise, but at 1000 rpm, they are fine.

Excellent fan, relatively quiet, with good concentrated airflow, durability, sturdy construction, and a four-pin PWM connection for full control of operating speeds with low power consumption. A very good choice for its price. I recommend it.
