With Scythe's black Kaze Master Pro 3.5, four fans can be controlled independently and four separate temperatures can be monitored in either Celsius or Fahrenheit. An integrated acoustic and visual alarm function warns users of an overheating system, or the failure of a system cooling fan. The acoustic alarm feature can be deactivated by a jumper setting, should you choose to do so. The integrated vacuum fluorescent display in blue enhances the overall styling of this attractive and useful addition to your PC housing. Fan voltages can be independently set from between 3.7 to 12volts and you can also completely switch off each fan, so you can tailor air flow and system noise output to personal taste and thermal output requirements. This package includes the Kaze Master Pro 3.5 fan controller unit, five temperature sensor cables, four fan extension cables, adhesive tape for mounting your temperature probes and mounting screws for the controller itself. This eye catching and attractive black faceplate fan controller occupies one chassis 3.5" external bay and is the perfect functional addition to your current or next PC system.
