Akasa AK-FN059 12cm Viper High Performance 120 x 120x 25mm S-Flow Fan by Akasa

These are great fans but I ordered 2 - 140mm Viper High Performance fans and had to return the 120mm which was only a small inconvenience. I use them to replace the 140mm Nocturas for intake and exhaust. They are only slightly louder than the Nocturas but move much more air at relatively low RPM's.

Ventilateur super performant, très Bon rapport qualité prix par rapport a d'autres marques plus cher.

Fa un ottimo lavoro ad una rumorosità bassissima. Vengo da una ventola scythe montata sull'omonimo dissipatore come configurazione di fabbrica e ho notato un miglioramento delle prestazioni e una diminuzione del rumore. Consigliata, al pari delle più blasonate Noctua

Melhor do que eu esperava o RPM chega a 2100 melhor do q os 1900 descritos pelo fabricante.

I've been using these fans for a while because they are perfect for the job and last (my oldest one is over three years old and still just as good as the day it came out of the box). Great airflow (even at lower speeds), nice and quiet below 80%. One machine I use these in is a HTC box, two running as the exhaust, they're at around 45% voltage and near silent, you only hear them when your head is next to the case. Even at this lower voltage they still move a decent volume of air. The connector for the fan is pwm, so if your board can do it, it'll control the speed itself. Also included are four silicon fan mounts which are top notch quality aswell. Cant recommend enough

風量は極めて一般的なDCファンです。 風量重視型のFanと比べて最大回転数で運用してもさほどうるさくはありません。 光るのは好きじゃないが見た目にはこだわりたい人には向いてる製品です。
