静音・風量に文句なし!値段が・・高いよ・・

Protoolsで使うxMac mini Serverの冷却ファンがクルクルドライヤー並みに爆音で仕事に支障が出るので仕方なしに買いました。静音・風量に文句なし!非常に素晴らしいですが、値段が・・・通常の4cmファンの20倍って。。・・・仕方ないです

よ**ん

風量は少なめです。

確かに静かですが、羽の面積が少ないので、同じ外形のファンと比べて風量が少なく感じます。羽面積の大きいファンを回転数を落として使った方が良いかも知れません。

品**ー

過大評価されている。

それは、あなたが期待するようなものでも、このブランドが言われ続けているようなものでもない。まともなノイズ/パフォーマンスを得るには、BIOSで直接速度を設定する必要があります。さらに、このファンは決して安くはありません。
