Quite reliable for their price! The good thing about them is that you can connect one with the other if you don't have space to connect them. Nice design and relatively quiet, I would say. When the PC is on at night and you scroll quietly, then you will hear them.

It is affordable, (Not completely, but it doesn't bother me at all). For its price, it is a good solution

I replaced 2 Corsair fans in front of the 760T after 6 years and I am very satisfied.
In silent/normal speed as an option from the motherboard and 70 cm away from me, they are not audible at all.
A decent choice for their price if you don't want to spend more.

It is the best value for money. They are not completely silent, but they do their job and more. They also come with a 6-year warranty each. Satisfied

First of all, I have a Ryzen 5 1600. Since I got the two 140mm fans for the front, the temperature has dropped by 6-7C, so you can understand what a great value for money it is! I have the RPM set at 600-700, they make a little noise but not excessively, maybe in the summer I'll need to turn them up to the maximum. CPU 100%

For the money, they are very good fans. I have installed 2 of them in a Phanteks p300 case, they have good cooling, I run them at 950 RPM and they do a very good job with minimal noise that you don't notice. If you don't want to spend more than 10 euros, it is a cheap and good choice.

The ultimate 14cm fan for under 15€ with a huge warranty! It only makes noise from 60% and above, I think it's manageable even at 70%. For someone like me who wants a completely silent system and has gotten used to silence, I found the perfect solution!

For its price, it's a one-way street.
I have them in Phanteks P400s and they are really silent.
Being 140mm, they don't need many rotations to bring in air, so they are silent. Increasing the rotations, it's hard to hear noise unless you max them out (without gaining much in performance).

The PST technology helps a lot for motherboards with few ports, but also to gather the cables on the back of the case and not have 2-3 separate ones running.

The negative is that the cable is not sleeved and the internal colors are visible (of course, we shouldn't expect everything at this price).
Anything up to 10-15 euros performs the same, and if you don't plan on having any RGB-LED, I can't find a reason not to prefer them

I don't argue that for its price, it is the best. I have 3 of these in an NZXT 340 ELITE case and I am very satisfied! Also, the blades take on the color of the LED strip or any LED you have! After 1000RPM, they make a little noise but there is no need to go above 1000RPM because it creates very good airflow... I highly recommend it, choose this specific model (PWM PST) because Arctic produces many similar external fans.

The most value for money I found in this specific size.

Very good airflow and even at full speed, a very satisfactory noise level (even compared to more "branded" models at much higher prices).

The only negative (for me) is the lack of a cable sleeve, mainly because the 4 different colors of the individual cables are visible
