Akasa 12cm Viper Fan


Pros: PWM, High static pressure, Good flow to noise ratio

Cons: None

Hands down the best fans I have ever owned. I have these and the lower speed version, the Apaches. I use the Apaches for the fans that are mounted close to the outside, and use these on the inside fans. Come pre-sleeved with high quality sleeving. The static pressure on these fans are top notch, and they also support a great long life and quiet bearing.

IMO, these are best use with a PWM splitter like the Akasa Flexa or Smart Splitter. As they allow you to control multiple PWM fans with one CPU PWM fan header without worrying about overloading your fan header as they supply their own power to the fans. Then you can control basically all your radiator, or even case fans, based on your CPU temperature.

Here is a picture of my Vipers on my 200mm radiator with a custom made plenum.
Akasa 12cm Viper Fan

High performance 12cm fan with S-FLOW blades supplying 30% more airflow than a standard fan at the same speed. The greater performance combined with PWM automatic speed control allows the fan noise to be kept to a minimum. The Viper fan creates more focused airflow providing blind-spot cooling, which makes it an ideal solution for a case or heatsink fan. HDB (Hydro Dynamic) bearings extend fan life and further enhance noise reduction. Killer Viper yellow colour makes this fan distinctive and unique.
