the fan will not fry. the amount of current (amps)that flows to the fan is determined by the internal resistance of the fan. the fan would have a very high resistance so as long as the source is 12v only a fixed amount of current will flow to the fan REGARDLESS OF THE SOURCE.
Can you explain why?
but putting 1.5 volts in series does not make 12 volts. Amperage increases but not the voltage. :)
it will only draw what is determined by the fan's internal resistance. the only way to burn the fan would be to hit it with very high voltages as an increase in voltage would allow for an increase in current flow at a given resistance.
My question is will the fans take the amps and burn the PCB or will it draw what it needs or run in normal operations. :)
Could you PLEASE! provide like a picture or video? :D
ok the capability of the battery is very high but think of it like this, current is not "pushed" it is "pulled" by what ever presents the load.that load is determined by the resistance. a high resistance means that little current will flow and thus a small load(because there is a lot of resistance to current flow ) . now with a low resistance there would be great current flow. with a cpu fan there exist a high resistance and thus as long as the supply is around 12 volts it would draw as much current that it is rated for on the back of the fan
Although the volts are the same the amperage is very high and it will most probably fry anything you hook up to it. The power supply is made to draw and supply as much power as needed, the car battery always supplies the same power (peak power) when it is above 20% charged. Do not try it.
Edit: You would need a controller between the battery and any device you hook up, in that case it should work. Power equals voltage multiplied by current (P=V*I) and unless you do something to control the current (and thus the power supplied) you are going to destroy your fans.
