Modest price for modest performance

The manufacturer displays 1,200 rpm, in reality it is between 800 and 900 turn.

Personally, I'm not disappointed, because I already knew the brand "Advance".
But I bought 2 fans of this type to circulate the air inside my turn, and they fulfill exactly the function I asked them: Create a constant air flow inside my turn.

I use them in addition to 3 Noctua 140mm fans (two on the radiator, and 1 to the outlet mouth), 3 Cooler Master fans (at inlet). All this allows me to maintain my PC at a temperature below 40 ° C.
