Max,
I've put a couple of photos of my J7F2 board here:
http://chezphil.org/tmp/j7f2_cpufan_top.jpeg
http://chezphil.org/tmp/j7f2_cpufan_bottom.jpeg
In the top photo, you can see an unpopulated position for a transistor
("Q1") next to the CPU fan connector. In the bottom photo, you can see
a "zero-ohm resistor" and some more unpopulated positions (the three
pins on the left of this picture are the bottom of the fan connector).
If your board looks similar, you're right that you can't control the
fan speed. If you have a transistor and other components near the fan
connector, then keep trying!
Phil.
