Se hizo el silencio
Su arranque es progresivo y silencioso, antes encendía la impresora 3d y parecía que había arrancado un tractor y ahora tengo que mirar la pantalla porque creo que no se ha encendido.El envío como siempre, genial.

音が高音で煩い
DC-ACインバーターのFANが壊れた為、40mmが必要で取り敢えず購入しました。予備も考えて5個セットで購入です。風量は結構あります。インバーター内部も確実に冷えます。音は高音で煩いです。風量を得る為に高回転になり、煩いのかもしれません。抵抗を入れて回転数が落とせれば良いのですが？★結論★ FANの仕事はしっかりやるが、兎に角煩い。

Cheap and Useful
These 40mm 5V fans come in a nice plastic case. The small 40mm 5V fans are very useful for smaller projects with MCUs, Raspberry Pis or MOSFETs involved so it's worth picking up a 5 pack. At about 2 bucks each, they're a pretty good value too. Running them at 60% PWM seems to be more than adequate cooling and also keeps them in a nice and quiet zone; when running them at full blast they do output quite a bit of air but also become high pitched and annoying.
