Correspondence of All-in-one Fan
Four fans support the Bitmain Antminer KA3. The miner will shut down and the protection will not function if a fan malfunctions. This means that when replacing, typically only the corresponding fan can be replaced.
The fan number on the control board corresponds to the fan number on the miner’s user panel. Simply locate the fan socket on the control board that matches the fan number of the user panel failure when replacing. (FAN1 and FAN2 are typically the rear fans, while FAN3 and FAN4 are the front fans.)
Steps to Disassemble the Fan of the All-in-one Machine
- The control board cover and the power supply cover should be taken off first (the front fan can also remove the control baffle without removing the power supply cover). Lift the cover plate up to remove it, then unscrew the corresponding screws. (It is necessary to press down firmly on the round button to remove the control panel cover.
- After removing the upper cover, cut the cable that supplies power to the corresponding fan.
- The fan cable protection tape should be peeled off, along with the corresponding fan cable tie.
- Under the copper bar of the power supply, the rear fan wire is located. The copper bar has enough room underneath it. The copper bar does not require removal. The copperbar can be accessed by the fan wire.
- To remove the fan, unscrew the four screws that go with it.
Note*:
1. Replacing the fan does not affect the warranty.
2. When installing the fan, pay attention to the direction of the fan. The fan’s wind flow should be from front to back.
