Windows 10 Pro:
So you have your MLD running and in the command window you hit Q for quit.
At that point the fan goes into a super fast full speed! Why?
If you then unplug the stick and plug it back in (I am using a powered hub) the fan still runs at hyper speed.
If I then run BFGminer again, the fan slows a little once it starts but not at the original speed it was running at. It's still running faster.
I have to reboot the PC to solve that. A reboot and then plug the stick back in and the fan is quite and lower speed again.
Run the BFGminer again and all is good. No hyper speed fan.
Anyone else notice this? Any way to resolve it?
Anyway to read the fan speed on this thing?
Thanks,
Bob
The fan is dumb, and its speed is based on the input voltage. When you first plug in the stick is not drawing any power you getting full 5v out of the port and so is the fan (so its running at full speed). Once you start hashing the voltage can drop down to as low as 4v depending on how bad the 5v supply powering the port is, which in turn slows down the fan.
