Hi bombadill25,

It's a long time since I worked on a desktop, but from your description and allowing for my failing memory on this I would guess that it is the fan speed control connection.

If so the connector will be located close to the 20 pin main connection from PSU to motherboard and may possibly be marked 'fan'.
