But you don't get all this with 2$:
Features of the control unit:
Free configuration, operation and monitoring with Windows software, connection via internal and/or external USB
Free definition of temperature and speed with response curves, ideal adaption to the inner life of a PC
Unit has its own microprocessor chip, which works independent from the motherboard: no performance loss and increased security
95% degree of effectiveness with no performance loss or heat dissipation
4 Mainboard outputs for the tachosignal: Tachometer with delivered Windows-Software or with mainboard monitoring tools
Unit does not take up valuable space, can be installed internally
Language support for English, German and soon more: Skins and language files are editable
Open source for communication protocol: for new independent software developments
Firmware update via USB
Features of the fans:
4 separate configurable channels, each channel with 15 Watts
separate speed recognition and 4 separate tacho signal output to mainboard
accurate speed control in manual or automatic mode via editable response curves
fans can be control to an absolut speed minimum, down to 2% depending on fan model
with analog smoothing and filtering a quiet smooth operation of fans will be ensured
with the Attenuator an additional smoothing ensures even more silence at very low speeds (10-30%) and a compability with all fans
adaptive PWM allows to adjust frequence for every fan model to avoid noises
free definable hysteresis allow a smooth operation even at steep response curves, no "up and down"
manual switching of fans possible
start-up speed test ensures operation of fans
0 rpm speed possible: if temperature rises, the controller speeds up the fan according to the response curve
Features of the sensors:
supports up to 8 sensors
accurate, digital, linear band-gab sensors (0°-125°C)
all temperature sensors can be calibrated separately
temperatur sensors are connected with a new easy plug bus system: not every sensor to the central unit (no spaghetti), but from sensor to sensor
free assignment of sensors and fans: many sensors to one fan (the hottest counts), or many fans to one sensor possible
Safety features:
start-up check during system start: all fans are tested shortly with 100% speed
sensor loss control: if a sensor looses its connection, the connected fan will be speeded up to 100%
Built-in protection against permanent fan blockage: if a fan stops, the controller speeds up to 100%. If that does not help, an optical and acoustical alarm will be performed
If the critical temperatures exceed: fans are switched to 100% and an optical and acoustical alarm will be performed
Manufacturer defaults: all fans switched on
Fail-Safe: if a hardware error on the controller occurs, all fans are switched on
optical and acoustic alarm signals: integrated LEDs, connector for external LED and integrated loud buzzer
speed meter functionality with outputs to mainboard
Modding features:
Connect some CCFL to your T-Balancer and get additional effects:
manual switch and dim
temperature-sensetive dimming
free configurable switching limits
with an additional software: light effects (fast sequences, stroboscope, waves and more)
with an effect editor (editable of parameters in a text file)
Its like you can buy a case with 5$ but then again wouldn't you just love brand new Lian Li?
