I have a Compaq Presario S6300NX and I have downloaded the manual to see if I can read up on installing an Aftermarket fan, to blow OUT the hot air accumilating inside the box. I have the fan, and have connected the connectors to the "CHA Fan" connector on the Motherboard.. I turned back on the PC only to find the fan never turned on at all. I'm confused, and I have no clue where else to connect this Fan (as I can only see 1 spot, CHA Fan to connect to). Any ideas?
