Quite good performance for slim fans and relatively quiet at full load of the computer. I got 3 because in the Deepcool CH160 where fans can't fit on the top and bottom of the case, the P12 slim came and solved my problem.

Very satisfied, it does its job and fits in a space where a standard 120 fan cannot fit. Aris is quiet and has good performance

The money that Arctic plays with its fans makes you feel like a fool when you buy from another company, for 6.5 euros, what can I say, it beats fans that cost 20 and 30

Awesome little fan at a great price that will solve your hands for towers with limited space. The airflow is very good, the performance is comparable to Arctic's conventional thickness fans, and the noise is minimal. I had an issue with fitting it on my Arctic Liquid Freezer II 360 cooling tower as the radiator is bulky and the conventional fans couldn't fit at all. I replaced them with these, the problem was solved, and the performance of the cooler remains at expected levels. Excellent.

You can't not give it a 5/5 for two main reasons. 1. It is quiet or at least with very low noise when it works high up and 2. Its price. If you take into account that it is a more specific solution when fans don't fit, for example 25mm, then it is an excellent choice. The cable that branches out is good, although personally I use a Y-type on the motherboard.
