Default Re: Damn it. Voltage on 13.8v PSU too high...

Just think of it in WCing loop in parallel with two block. You have Y and split into 2 inputs in the two blocks and have the 2 output of the blocks combine into Y.

PSU positive terminal < Resistor | Pump > ground terminal of psu.

----------PSU---------
----------- ^----------
-----------|--|---------
-------Res Pump----
-----------|--|---------
------------V---------
----------PSU---------

From positive terminal of PSU, you split into resistor and red molex of pump. Then you have the black ground terminal from pump and resistor connect into another Y before you finish at ground connection of psu.

You don't connect the resistor to pump but keep them seperately.
lol thanks I know what parrallel and series circuits are I'm no EE but took enough electronics classes to understand the basics. I just don't recognize components.

I put the 1k resistor and fan in parrallel and it still gave 15v. I just don't understand why increasing the load a little with a resistor was supposed to do anything? Voltage is constant across a parrallel circuit so if the fan was getting 15v why would putting a resistor in parrallel with it change anything other than the total current? I guess if the more load I put on it the voltage would sag but I put up to 35-40w and it still was above 14.8v.
