## Overview

The 2PCS DC 12V 4 Wire PWM PC CPU Fan Temperature Control Speed Controller Module is designed for high-efficiency cooling solutions. It supports all internal 12V 5A fans, allowing for multiple fans to operate in parallel while maintaining optimal performance. With four temperature zone settings and a robust circuit load capacity, this module ensures your system runs smoothly without the need for additional heat sinks, even under high current operations.

## Description

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

Review: Does what it says - I replaced the loud, 6000rpm, always on server fans in my UPS with 4 pin pwm fans and control them with this gadget. Before I could hear the UPS from anywhere in the house. Now it is whisper quiet but will still speed up if the UPS is under heavy load. Does what it says and despite the complaints coherent English instructions are readily available online. A few things to be aware of, Fan1 is the only fan header actually temperature controlled. The other 2 are just controlled via rheostat. I use a y cable to temperature control two fans at the same time. I am not using the beeper function so cannot comment on that.
Review: Good for price - Well, it does what it's supposed to do. 5 Stars because the description is accurate. Pros- Inexpensive Cons- -Only reads temperature in Celsius -Basic functions compatible with 4 Pin Only -5amp Fan Only or buzzer rings non stop -Very Limited Range of Temperature -No LCD display -No Instructions -Cheasy probe Mostly only useful for high temperature situations.

## Features

- 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)

## Questions & Answers

**Q: Can someone please explain the switches in clear English, not poorly translated gibberish?**
A: Here is what I gathered from the description:

TFL	ON				fan speed min of 40%
TFL OFF				fan speed min of 20%

TP1 OFF + TP2 OFF	95 - 113F
TP1 ON + TP2 OFF	104 - 131F
TP1 OFF + TP2 ON	122 - 158F
TP1 ON + TP2 ON		140 - 194F

BF1 OFF				No fan 1 alarm
BF1 ON				Fan 1 alarm if stopped
BF2 OFF				No fan 2 alarm
BF2 ON				Fan 2 alarm is stopped

The minimum fan speed is set by TFL.  When temp is below the low end of range
set by TP1 & TP2, the fan runs at mimimum speed.  When it is above the high end
the fan(s) run at full speed.

Alarm is set by BF1 (fan 1) and BF2 (fan 2).  If the switch is on and the
corresponding fan stops, or is not connected, the alarm sounds.

The board worked exactly as defined in the instructions.

**Q: what is the max input voltage?**
A: 12VDC
