Review: 取り付けも簡単。ファンが変わると全然音がが気にならなくなりました。効果抜群。
Review: 結構昔に購入したノクチュアのCPUクーラーのファンが固着して回らなくなったので交換。 同じものがまだ売ってて助かった。 ついでにケースファンも付属のから、これと同じものに交換。 静粛性に定評あるので、以前より静かに？なりました。

*by K***K on June 5, 2018*

机の上にノートPCを置いて、PCファンで風をあてて冷やしています。800RPMの超静音ファンだと静かですが、風量が足りずにさほど冷えませんでした。このファンにしてLNA（ケーブル）を付けて回したところ、（当然ですが）800RPMの超静音ファンと比べて風量は数倍以上になり、また音も全く気になりません（ファンの直ぐそばまで耳を近づければ、やっと風切り音が聞こえる程度。800RPMの超静音ファンと比べても体感では変わらない程度。）。温度も5-6度程度は下がりました。LNA無しだと、風切り音が大きくなります。LNAはよく調整されていると思います。価格はそこそこしますが、これから暑くなる季節ですし購入して正解でした。
