Intel standardized four-wire fan control protocol, supports all standard four-wire interface chassis fan and CPU fan control, while more than 95 percent support violent fan speed control, three-way independent control of different functions, with the way temperature shift and two-way stall detection alarm function (with accessories), the largest single-channel support 12V5A fan, the entire board supports up to 12V9A total current input
Currently recording uncontrollable four-wire Fan Model Summary:
Delta FFR0612VHE, FFR0612DHE
Dimensions 6038
Non-standard anti-timing fan (reverse adjust speed)
Feature:
Board size: the length and breadth 50mm x 43mm x 13mm, the positioning hole position 44mm x 37mm, 3mm diameter
Operating voltage: DC12V
Circuit load capacity: maximum current per output 5A, the bus currents up 9A
Output Range: The first channel 20% -100%, or 40% -100% (TFL = ON)
10% -100% of the second path and the third path
Note: The above range only PWM range, the actual fan control effect will vary depending on the fan.
Temperature probe parameters: 50K B = 3950
Thermostat temperature zone error: error depending on the temperature probe, generally 3-5%
Stall alarm minimum speed: 700-800 rpm
Function setting switch Description:
TFL (No. 1): PWM channel with the lowest temperature setting, when ON, the lowest PWM of FAN1 is 40%.
When OFF, the minimum PWM of FAN1 is 20%
TP1 and TP2 (No. 2 and 3): Temperature channel control temperature zones are interpreted as follows (need to match the temperature probe used):
TP1 |
TP2 |
Accelerated temperature |
Full temperature |
OFF |
OFF |
35℃ |
45℃ |
ON |
OFF |
40℃ |
55℃ |
OFF |
ON |
50℃ |
70℃ |
ON |
ON |
60℃ |
90℃ |
Lower than the temperature of the minimum rotation speed output accelerated over full temperature is always full output.
(BF1, BF2)Correspondence FAN1, FAN2 stop the alarm function switch. When the corresponding open, The controller will sound (with buzzer needed) and light alarm, Fans restored after the alarm is cleared automatically rotated. If BF1 and BF2 are open (ON), the FAN1, FAN2 have any one or two stops, the controller will alarm.
Note:
Please note that the controller is a four-wire PWM fan controller can control four-standardized protocols in line with Intel's four-wire fan (all four lines of the chassis and CPU fan are met, a server with more than 97% can control fan violence). Unable to control two-wire or three-wire fan, you can not completely turn off the fan!
