when ever i am inside my computer, i always try to avoid moving the fan blades becuase i thought it could damage the mobo sending current through it the wrong way, the idea is this:
a fan is essentially a motor with fan blades on the motor shaft. What i understand about a motor is that when the motor is off, any movement at the shaft end sends current back through the motor - essentially creating a dynamo.
another thing i like to do is when i shut down my machine, watch the fans spin down... AND then i thought:
- the instant the mobo shuts down and stops supplying the fans with power, they still keep spinning due to their momentum - so they must also be sending power back into the mobo
my question is this:
-is my logic correct?
-and if so, does the mobo have some sort of regulator to stop negative voltage being sent through the board?
-is my wariness of moving the fans when off justified?
(BTW, this is just something that came to me the other night when sitting here, it is not important or urgent, just interesting
)
