Overheating protection #208

Closed Shen closed 5 months ago

Shen commented 5 months ago

I found this report.

I didn't have this issue yet, but is there a proper overheating protection implemented?

It is possible that this might happen. I have noticed that in version 2.1.7, the fan stops working when the device is turned on if it is not connected to any Wi-Fi network. I think the fan should always be running to prevent these issues.

Agreed fan should always be active as protection. Should be no time the fan is off.

Procedure to Stop the Fan:

  1. Set Up a Non-existent Wi-Fi Network:

    • Configure the Bitaxe to connect to a Wi-Fi network that does not exist, or simply disconnect your Wi-Fi router.

  2. Reset and Disconnect Power Supply:

    • Press the reset button and then disconnect the power supply. (Note: Just pressing the reset button won't work; you must disconnect the power completely.)

  3. Reconnect the Power Supply:

    • Reconnect the power supply to turn on the Bitaxe. (The device will attempt to connect to the non-existent Wi-Fi network, causing the fan to turn off.)

  4. Maintaining the Off State:

    • If you press the reset button again, the device will restart, and the fan will remain off.

Other Method to Turn Off the Fan:

  1. Correct Wi-Fi Configuration:

    • Configure the Bitaxe to connect correctly to a valid Wi-Fi network. Save these settings.

  2. Reset and Disconnect Power Supply:

    • Press the reset button and disconnect the power supply. (Again, this won't work with just the reset button; you must disconnect the power completely.)

  3. Reconnect and Wait:

    • Wait a few seconds, then reconnect the power supply. Allow time for the Bitaxe to connect to the Wi-Fi network.

  4. Temporary Fan Shutdown:

    • The fan will turn off for a few seconds while the screen displays "0 hashes per second."

  5. Fan Resumes Normal Operation:

    • After a few seconds, the fan will turn back on, and the Bitaxe will resume normal operation.

Note:

It's unclear if turning off the fan also disables the overheating protection system. Both aspects should be reviewed to ensure proper operation.

You're right, having the fan off is not good. I'll look into this. In the mean time, do not let your bitaxe run without the fan spinning!

Please test with the new 2.1.8 release; https://github.com/skot/ESP-Miner/releases/tag/v2.1.8

Fixed! In my Bitaxe, the fan no longer stops like it did before! Great!
