Hello everyone,
I was mining on the Willipool with a Nano 3 like several people here, the miner was purchased in January 2025, it was set to High mode and generated the expected 4 Th, the two plastic covers were removed for better cooling.
It started to malfunction several weeks ago and finally stopped a few days ago. I noticed that the usb-c connector used to power it had literally melted, with traces of overheating in the connector housing on the Nano.
For a device requiring only 140 W to operate at full power, I'm not sure this type of connector is the best choice.
My message to all owners of these devices is to be vigilant if they're running in High H24 mode, and to check regularly that they restart without load.
I'm in discussion with the retailer, a store in Paris (phew, I don't have to deal with Canaan about the warranty).
Good day and good mining to all
