🔧 Main Functions
The fan generates forced airflow to control the temperature of electronic and power components.
The four-wire connection allows, in equipment designed for this purpose, electronic speed management via PWM, in addition to power supply and control/monitoring signals.
🔌 Purpose and Operation
It is used to dissipate heat generated by power semiconductors, power supplies, converters and other electronic components.
The high speed and good static pressure make this model particularly suitable for equipment where airflow must pass through heat sinks or relatively compact spaces.
🧩 Compatibility
It can be used as a replacement in equipment using the MGT6012UB-W25 or a fan with equivalent characteristics.
Before replacement, always verify:
-
12 V DC power supply;
-
60 × 60 × 25 mm dimensions;
- current consumption;
- mounting hole arrangement;
- number and function of wires;
- connector;
- PWM control;
- airflow direction.
The fan should not be attributed to a specific inverter model based solely on the photograph, because the MGT6012UB-W25 is also used in other electronic equipment and power supplies. It is also documented, for example, inside high-power workstation power supplies.
⚠️ Typical Faults and Symptoms
A worn or faulty fan may cause:
- failure to start;
- intermittent rotation;
- insufficient speed;
- abnormal noise;
- vibrations;
- rotor blockage;
- reduced airflow;
- increased internal temperature;
- activation of the equipment's thermal protections;
- fan fault indication, when provided by the system.
🚨 Possible Associated Errors
The error code depends on the equipment in which the fan is installed. A fan failure may generate indications such as Fan Fault, Fan Error, Over Temperature or Thermal Shutdown, but there is no universal error code directly associated with the MGT6012UB-W25.
🔍 Diagnosis
For verification, it is advisable to check:
- presence of 12 V DC;
- fan current consumption;
- correct startup;
- rotation speed;
- PWM command;
- possible tachometric signal;
- noise and vibrations;
- freedom of rotor movement;
- condition of cables and connector.
🛠️ Common Services in Case of Failure
- Fan cleaning.
- Wiring inspection.
- Power supply verification.
- Rotation and PWM control testing.
- Bearing inspection.
- Complete fan replacement in case of wear or failure.
