Description :STW-5006 is a automatically fan controller， it can automatically test the computer temperature and display the screen， when the computer need to transport big volume files the fan controller can automatically increase the computer rotate speed to reduce the computer temperature， meantime when the computer is in spare time the fan controller can lower the computer temperature as well the noise to well protect the computer. moreover the fan controller also can hand set up the computer's alarming temperature range from 40 degree to 90 degree， when the computer exceed this range the fan controller will be stuck and automatically call the alarm， so it can effectively avoid the computer damage caused by the heated devices.The industry's most valuable belt shows the fan speed，the temperature display mode can be switched in ℃/FA set of temperature measuring temperature: the temperature range of 0 ℃ ~ 99 ℃.High precision temperature probeA set of fan the measured speed display， have stuck detection， alarm prompt. Automatic temperature Detection of fan speed control60 ℃ overtemperature alarm. Emergency alarm real-time display and can be manually (45 ℃ ~ 99 ℃)One temperature test:the scope 0~99°C，the error:±1°C Parameters :Brand:STWOutput voltage:5v-12vInput voltage:5v and 12vFan connector :3 pin ，4 pinPower Interface: big 4pinPower: 10wSize:14.9 x 10.0 x 4.2cmFan cable: 620mmScreen:LCD displaySpecial function:manual set up the alarm temperature1.
