Thanks all
I unplugged the PSU, took off the fan, and took a small nail and released the latches on the connectors, and swapped out the black one and put it in the rightmost hole, then left the remaining ground and the red connector from the PSU extender on the fan cord hanging out (they're not connected to anything so it's not like they're a shock hazard, right?
) in case I decide to use them again.
Anyways, I plugged it onto the fan chain I had going, and I didn't realize that the beginning of the fan chain was not even plugged in until I turned the computer on.
So then I shut the computer off (didn't even smell burning, heatsink wasn't hot or anything like that), and plugged the fans into the correct plug, and turned it on.
SWEET BEAUTIFUL SILENCE!@#
Well, almost. Before, it sounded like 2 vacuum cleaners. Now it sounds like about 3/4 to a whole vacuum cleaner. But it's a shitload quieter than before. Dropped about a thousand RPMs and found my hard drive's clickety click sound again.
