datasheet feels the sting

But that silence comes at a price: this fan does not breath! It is totally anemic, even at 12V. It just provides a stream of air, enough to silence something almost useless: stir the air without really circulate. I ordered two, and both give the same result. This is not an isolated defect.

The advertised rate (71 m3 / h!) Is probably fanciful. Comparing it to my Noctua (in 92 and 120 mm), I would say barely reach 30 m3 / h. Just as much as a Noctua 92mm 5V.

The price can be explained better, and on that side, it is not stolen. But the technical characteristics are more qu'exagérées, and that's unbearable.
