High performance 14cm 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.

"The Viper costs less than most other fans it has been compared against in the previous page and this is definitely a big plus point. Packaging was good also, and the fan build quality was decent as well. The fan uses a fluid bearing which is pretty much a long life sleeve bearing, and is not high on power consumption either. Pure performance as a radiator fan was not bad either, If you are looking for yellow fans out of the box, these merit a consideration- the Viper 140mm is not too bad for the money."
