2PCS DC 12V 4 Wire PWM PC CPU Fan Temperature Control Speed Controller Module CPU High-Temp Alarm

Specifications: Temperature probe parameters: 50K B = 3950 Thermostat temperature zone error: The error depends on the temperature probe, usually 3-5% Stall alarm minimum speed: 700-800 rpm Function setting switch description: TFL (No.1): The lowest temperature channel PWM setting. When the ON state FAN1 PWM minimum value is 40%, when OFF, the minimum PWM of FAN1 is 20%. TP1 TP2 (No. 2, No. 3): The temperature channel control temperature range is explained below (requires use with the temperature probe): TP1 TP2 accelerates temperature at full speed OFF OFF 35°C45°C ON OFF 40°C55°C OFF ON 50°C70°C ON ON 60°C90°C When the temperature is lower than the acceleration temperature, it is output at the minimum speed; when the temperature is exceeded, it is always output at full speed. BF1 BF2 (No. 4, 5): Corresponding to the FAN1 FAN2 stall alarm function switch. When the corresponding open channel fan fails, the controller will use the sound and light alarm (working with the beep), the alarm will be automatically eliminated, and the fan will be rotated. If both BF1 and BF2 are ON (ON), FAN1, FAN2 have one or two stops, the controller will alarm! Note: The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully! Manual measurement, with small error. Please check size in detail before purchase. Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness. We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution. Package Includes: 2Pcs 2x speed controller 2x temperature probe 2x hum

• Supports all internal 12V 5A fans, synchronous rectified output, high efficiency, no need for additional heat sinks even for high current operation.
• Multiple fans can be used in parallel (total current does not exceed 5A), support automatic temperature control and air cooling speed control, temperature control speed has four temperature zone settings, widely used.
• It can be turned on with the three-wire fan monitoring function (stall warning).
• Circuit load capacity: 5A for each output and 8A for bus current.
• Output range: 20%-100% for the first channel, or 40%-100% for the first channel (TFL = ON), 10%-100% for the second channel and the third channel. (Note: The above range is only applicable to the PWM range, the actual control effect will vary depending on the fan)
