Review: 知らぬ間にsilent wings 4シリーズが発売されていたので使用中の3との違いも確かめたくて購入してみました。 今回は140mmですが相変わらず静かなのに風量が凄いですね。高速回転させてみても耳につく音がマイルドなので嫌な感じが一切しません。 リアに排気で取り付けましたがケース内の熱気をしっかり吸い出してくれます。 お高めではありますが、MTBFが300,000時間(25℃)なので安いのを何度も買うよりはトータルのコスパは良くなると思います。 まぁsilent wings 3との違いは正直分かりませんでした笑
Review: 値段はお高いですが 値段に見合った高級感があります。

車内のサーキュレーターを自作するのに使用。 風量はあるのにしっかり静音でMAX時でも振動無し。 PWM制御も仕様通りの動作（当たり前か）
