Scythe Mini Kaze 50mm Fans Review
 

The Mini Kaze 50 mm from Scythe is a perfect choice for adding a bit of airflow in those hard to reach places, without impact the noise level. They can be used as extra chipset fans, replacement for external HDD case fans, or a replacement fans for small ITX cases.

Any word on the noise generated by these fans? I've been looking for a small, quiet fan to drop on top of my NB heatsink to try and bring its temp down (my CPU is water cooled, so it doesn't get much airflow and idles around 55C).

If they tested these fans in the same test room as their 120mm fans, it seems their 26dBA readings places it between a 1200rpm and 1600rpm 120MM fan
