Usage tutorial for ASIC miner F1 cooling fan tester

The F1 miner fan tester is applicable to the speed monitoring of fans of Antminer, Whatsminer, Avalon and Innosilicon. It has the function of testing whether the fan speed meets the standards, and the results will be directly displayed on the screen, enabling precise measurement of the fan speed.

Connecting the F1 fan tester:

1. The F1 fan tester requires a direct current 12V PSU for power. Connect it to the power source.

2. Place the fan that needs to be tested vertically on the desktop. Do not lay it flat. Connect the corresponding 4-pin, 6-pin or square 4-pin fan sockets according to the interface introduction on the product page of the F1 fan tester.

User interface description:

1. The test result after the fan is connected (valid when the current mode is "Auto", and the "Manual" mode will close the test result);

2. The real-time speed of the fan under test;

3. Fan speed adjustment, when PWM=100%, the fan will run at full speed; when PWM=50%, the fan will run at 50% speed; when PWM=10%, the fan will run at a lower speed;

Menu and function explanation:

In the user interface, short press the "MENU" button once to enter the menu, press the "+" or "-" button to adjust the parameters, and press the "OK" button to save the settings after adjustment. After entering the menu, short press the "MENU" button to switch options; when the option is "Device SN:," press "MENU" again to return to the user interface.

1. Test mode: (fan speed adjustment mode) has two options, automatic and manual. The automatic mode can quickly test the fan speed in stages. The PWM adjustment range of the manual mode is from 10-100%, which is suitable for driving an unconventional Fan (the part of the core fan will increase the speed when the PWM is reduced, and the speed will be reduced when the PWM is increased). It should be noted that after switching to manual mode, the fan speed qualification test function will be turned off.

2. Fan Test: speed qualified test, this option is valid in the automatic test mode. After turning it on, it will sample and compare the detected fan speed within the set automatic test time range. When the test time is reached, if the fan speed is lower than the user-set, if the test speed is unqualified, the horn beeps twice continuously, and the "test result" on the user interface is displayed as "failure"; if the connected fan speed and start-up time reach the parameters set by the user, it is qualified, the horn beeps once, The "Test Result" on the interface is displayed as "Passed".

3. Test time: test time is automatic test, take MARTECH 12V 2.7A (Antminer) fan as an example, means that the time required for the fan to go from 0RPM to 7000RPM after power is turned on is 5S. The time required for different sizes of fans is also different. The time can be adjusted according to the actual situation (the adjustment unit is seconds) , and setting a reasonable test time can effectively improve the efficiency of fan testing. When testing a fan that is running normally, the screen also shows failure. You can try to increase the automatic test time, and press OK to save after adjustment.

4. TSspeed: test fan speed, a qualified fan speed should be 6000RPM or above, we can set the parameter of  "test speed" to "7000" in this option; you can long press "+" or "-" two keys for quick parameter adjustment.

5. Language: the text displayed by the device has two languages, namely Chinese and English.

6. Sound: when the parameter is "On," the user will press the button and there will be a corresponding prompt sound, and the fan test result will also have a prompt sound. When the parameter is "off," the whole device is in silent mode.

7. Power en: restore power, refers to how long it takes to restore the fan power supply after short-pressing the “MENU” button. The default setting is 10 seconds. You can set the optimal parameters according to actual test needs.

8. Device SN: tester factory serial number.

Note: When testing the miner fan, it is necessary to keep the airflow from the front and back of the fan unobstructed. Otherwise, even a good fan may fail when tested.

Timely detection of the fan speed can help us effectively avoid fan failure problems in advance and ensure that miners maintain normal heat dissipation.
