LS3 Temperatures for Fan Kick On/Off?

this is what i found but did not know what resistor to use,  so the laptop screen went wild on the tach output, and other sensor went wacky, 

some say 1k some say 10k,  so i most likey did not match the sensor to the resistor,  

Then you can sell a wire harness that plugs into the 5v plug and the input plug and this would make it pretty turn key for someone 

So how do you determine what pullup resistor is needed,
