PerformanceAfter powered on the fan output will always be set to maximum.
All fan outputs of the XTunner are controlled by Pulse-Width-Modulation. It is not possible to change them individually.
There are 7 speed settings:
This is the slowest mode. The fan is run at 40% of maximum speed. The first LED is blinking.
The second speed setting turns the first LED on and runs the fan at 50%
When the second blue LED is on, the fan is running at 60%
The first green LED shows you that the output is running at 70%.
Another LED - another 10%, makes the output go to 80%.
Almost at full speed - running at 90%, the 5th LED lights.
On the maximum setting all LEDs are lit and the fan is run at 100%.
According to Thermaltake the unit is rated at 1A per channel, thats 12 Watts - we tested it:
All those fans are connected to one channel - the meter shows 1 Amp. We kept adding fans and at around 1.4 Amps the output power transistor got mighty hot. I would say 1.2 Amps (= 14.4 W) are a good permanent maximum per channel.
Thermaltake claims the range of the remote control is 12m. We verified this and found that with a clear line of sight we could control the fans from a distance of more than 15m.
