What is the replacing method for the Avalon DBPJ1238B2G cooling fan?

Avalon DBPJ1238B2G cooler fan is a professional-grade product specifically designed for high-performance miner cooling. It supports DC12V 3.12A, 7000RPM high speed with an air volume of up to 295CFM. Equipped with dual ball bearings and 4-wire PWM temperature control technology, it can precisely adjust the fan speed, providing stable cooling support for miners such as Avalonminer, Innosilicon, Ebit, Antminer, Whatsminer, etc.

When the miner's cooling fan malfunctions, it may lead to the following issues:

1. Abnormal fan operation: If the cooling fan does not operate or makes unusual noises when it operates, these phenomena are direct manifestations of its damage.

2. Significant decrease in mining efficiency: Fan damage directly affects cooling, causing the internal temperature of the machine to rise rapidly, severely affecting mining efficiency and reducing profits.

3. Frequent miner reboots: Due to excessively high internal temperatures, the overheating protection mechanism is triggered, causing it to frequently reboot automatically. This not only affects its continuous operation but may also accelerate the aging of hardware components and increase the risk of damage.

4. The damage risk of hardware: Prolonged operation in high-temperature environments can cause irreversible damage to electronic components inside the miner (such as GPUs, ASIC chips, power modules, etc.), significantly shortening the equipment's service life and potentially leading to more severe hardware failures.

Therefore, when we discover abnormalities in the miner's cooling fan, please replace it immediately.

The specific steps are as follows:

1. Locate the faulty cooling fan

(1) Check and confirm the number of the faulty fan through the miner's background operation log;

(2) Accurately locate the faulty fan based on the corresponding fan interface number on the control board.

2. Disassemble the miner

(1) Turn off the miner, unplug the power cord to ensure safe operation;

(2) Unscrew the fixing screws of the miner's case to remove the protective cover plate above the control board.

3. Remove the faulty fan

(1) Find the faulty fan, remove the fixing screws of the fan protective net to take it off;

(2) Unplug the corresponding fan plug on the control board, then carefully remove the fan.

4. Install the new fan

(1) Check the appearance of the new DBPJ1238B2G cooling fan to ensure no damage;

(2) Use screws to pass through the screw holes of the fan protection net and the cooling fan in sequence for later fixation;

(3) Align the fan to its original position, next tighten its fixing screws.

(4) Connect the fan plug to the corresponding fan interface on the control board, ensuring a secure connection.

5. Operational testing

(1) Install the protective cover plate removed previously, next power on the miner to observe the operation of the new fan;

(2) Through the miner's background, confirm that its temperature has returned to normal, ensuring a good cooling effect.

Good cooling is an important guarantee for the continuous mining of miners, directly affecting the mining efficiency and service life of the machine. Therefore, we should attach importance to the replacement of the faulty parts, ensuring that the miner's cooling system is always in the best condition to maximize profits.
