## Overview

This DC 12V PWM CPU Fan Speed Controller offers advanced temperature-based fan management with four configurable zones, supports multiple 12V fans up to 5A each, and features a dual-channel stall alarm system. Designed for high efficiency without extra cooling hardware, it ensures silent, precise, and reliable CPU cooling for professional-grade electronics and custom PC builds.

## Description

Support all within 12V 5A fans, synchronous rectifier output, high efficiency! Even if a large current work does not require additional heat sink! A plurality of fans can be used in parallel (total current does not exceed 5A), supports automatic temperature control and manumotive speed control, temperature control speed with four temperature zones for setting up, easy to apply in a variety of applications! It can be opened with a three-wire fan monitoring function (stall warning). Working 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) The second channel and the third channel 10% -100% (Note: Above range only for PWM range, the actual 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): The lowest temperature channel PWM setting, when ON state FAN1 PWM minimum is 40%, when OFF the minimum PWM of FAN1 is 20%. TP1 TP2 (No. 2,3): Temperature channel control temperature zones are interpreted as follows (need to used with the temperature probe): TP1 TP2 Accelerating temperature Full speed temperature OFF OFF 35℃ 45℃ ON OFF 40℃ 55℃ OFF ON 50℃ 70℃ ON ON 60℃ 90℃ When the temperature lower than the accelerated temperature, then output at the minimum rotation speed; when it exceed over the full temperature, then always output at full speed.

Review: Great for electronic projects - Easy to install and program
Review: Works well, some radio interference, easy to remedy - This board is controlled by a Nuvoton MS51FB9AE on my ZFC39 V2.0 board that I received a year ago. I'm putting it inside a solid state linear shortwave amplifier, and I need any RF noise from this board to be addressed so it doesn't affect the amp or reception. After some work, it's working great and keeps my fans silent at the 20% duty (3x Noctua NF-P14s redux 1500rpm) when the amp is not working hard. As-is, the controller creates radio interference noise in the medium- and shortwave ranges, due to the 25 kHz PWM that is applied at all times except when the fans are driven to 100% duty. I've tested with a good clean bench power supply, confirming the RFI comes from the board and emanates from the fans as well. The noise is sufficiently abated by shielding the controller, a dedicated AC/DC transformer for it, and its fan cables up to the point where they exit the amp, with perforated metal mesh conductive tape and grounding the tape to the amp case. In my setup, the "SY" pads are soldered together, which causes all three fan outputs to be controlled identically by the single temperature reading for FAN1, and the two potentiometers for setting fixed FAN2 and FAN3 speeds are ignored.

- BF1 BF2 (No. 4,5): corresponds FAN1 FAN2 stall alarm function switch, when the corresponding open channel fan break down, the controller will alarm with soundand light (works with buzzle), alarm will automatically eliminated when the fan is rotated recovery . If BF1 and BF2 both are open (ON), the FAN1, FAN2 have any one or both stops, the controller will alarm!

### ⭐⭐⭐⭐ Does what it says with some limitations
*by N***C on October 31, 2021*

As other reviewers mentioned, there is no real manual and Youtube is your friend! Fortunately someone did a great video about it (title: ZFC39 PWM Fan controller). Key point is that any dip-switch settings only take effect after powered off and on again. It supports three fans, but only the first one is temperature controlled. The other two are via the potentiometers. You can only specify some temperature levels, but not the hysteresis. Wish it only supported one fan, but gave you more options on base speed (my fan didn't even spin at the possible base speed settings), start and max. temperature.
