they connect and work well with my b550m micro atx motherboard and the rgb is really nice too would highly recommend.

Silent with great argb and airflow

How is it possible that in the same order there are two products, one arrives at its destination immediately without any problem and for the other they are looking for us and calling us for three days supposedly because they can't find us...

Absolute VFM. Replaced 4 old 3-pin fans in my daughter's computer and now the difference in noise is like night and day. Completely silent. A big plus is that you can connect up to 5 fans together and plug them into a single fan header on the motherboard. Especially useful for those whose motherboard doesn't have many fan slots. I hope they are also durable over time.

The build quality is "just okay", you can feel it's budget in your hand. But you don't care, you won't throw it at the wall and you want it not to break. In terms of performance, they are extremely good fans. Especially when it comes to performance/price ratio. You pay much less than what you get.

Excellent cooling and silent even at full load. I have 7 of the same in my system (5 in the case + 2 in the cooler) and they are not audible even at full load.
I should note, of course, that I don't have the case on the desk but below it.

Easy installation, quiet in operation and helps a lot (in my PC) to expel the air and I have seen temperatures drop. For 5€ it is very good, I recommend it

The most VFM! Obviously, they don't have RGB but they do their job perfectly and will never disappoint you!!
I may have used these particular ones more than 5 times for different computer builds!

Quality construction, replaced an old fan on a very old Enzotech Ultra-X from 2008 (LGA 775 2500k) which was a replacement for the original one from 2007 whose bearings had failed and was noisy, now completely silent and cools perfectly.

the best you can get at this price, especially in white. there may be slightly quieter fans from other well-known companies, but at three or four times the price. for me, I consider it the best for VFM airflow and noise are perfectly acceptable and satisfactory. if you want to run them at half speed, they are very quiet; otherwise, at full speed, they are audible.

It makes a bit more noise even at 50%. Otherwise, I did not notice any problems after several hours of use.

At this price, they have no competition. PWM so it can be adjusted from silent to noisy. But they push a lot of air. Almost comparable to much more expensive ones. The chain connect is a great help, just check what your motherboard's socket can handle

I have bought about 15 in total. Very good and economical fan, silent with a long cable and daisy chainable. After almost 2 years, the 2 that were upside down at the bottom of the box broke, but that happens. I recommend it without reservation

The best value for money in fans! Extremely quiet even under prolonged stress. Anyone who doesn't want to spend a fortune should go here with their eyes closed. Arctic is a guarantee! They also provide a 10-year warranty!

Very good vfm, they are relatively quiet and even though they don't have any bumper to avoid touching the box, I don't hear any rattling

Excellent for the price, the noise is no issue especially if your PC case is big and has some noise absorption capability(yeah sounds funny but differs from case to case). The airflow is great and the temperatures remain low even under intensive gaming/rendering.

Very good and quiet. The fact that it can be connected in series with others is very useful. Ideal solution for any system

Easy installation, quiet. They can also be connected in series in case the cable doesn't reach the motherboard or the hub. Now regarding the airflow, if proper placement and correct selection of intake and exhaust are done, combined with a good case, the cooling is very satisfactory.

So far, it's quiet, with a fairly easy installation. I'm not sure if rubber washers are needed for damping synchronization and vibrations. Combined with Arctic Case Fan Hub - PWM Sharing Hub for PC.

A fan from the set has started to make a bit of noise, somewhat annoying.

Do you want cheap, decent fans? That have good airflow and are not noisy? You won't find a better price, I use these or the 140mm ones in 4 of my computers and I've never had an issue

Cheap and reliable lights. By adjusting their rotations, they become almost silent and the installation is easy.

They seem good, they do their job logically, but I wouldn't call them silent in any way. Their smart fan control has them running at least at 1100-1200rpm to maintain temperatures, and I must say, they sound a bit like airplanes. The previous ones I had, which were somewhat cheap, were hardly ever heard, and I changed them mainly because one broke down and I thought, why not just change all four.

I tweaked the fan curves in the BIOS and after lowering their speeds quite a bit (and the CPU cooler's as well), I can say they are as quiet as the previous ones I had, with similar temperatures, meaning good.

Update: After 2 months, one out of the 4 started to rattle when running at low speeds. A bit disappointing, I will probably get another one like it to replace it and I hope the others don't start doing the same after a couple of months.

Excellent choice for €5, I can say that it has helped me quite a bit and I have reduced the processor temperatures by 5-10 degrees with just one fan depending on the usage

25 euros for this is a steal, great fans. especially when you consider a single noctua fan costs that much.

For the money, it is the best I could buy. Quite silent with very good airflow. The cooling it provided was noticeable with very low temperatures.

The most value for money in fans! I have had them for over 4 years and I have put them in 2 different cases (because I changed the case). Very good airflow and most importantly, the fans are not noisy

For their price, they seem quite good and efficient. They maintain temperatures well in the PC and are quiet when working up to 35%. Beyond that, they start to become noticeable but not annoying. The build quality seems good and the RGB lights are bright. For their price, you definitely get something quite quality compared to other similar-priced options.

As I said in the review with the 3 pieces:
I think by far the best purchase for the PC!
At first, I only had 3 front fans, but because the stock fans of the cooler were noisy and I wanted all the fans to be the same, I bought another 3. With the change in the cooler, I also had a decrease of 3-4 C in the CPU and generally in the motherboard, which shows that they expel hot air faster from the case than the stock fans. The 6 fans also run from one ARGB header without any issues.

Very good. Good construction, fast, quiet, and good software
