Judging from the kernel; source it looks like it should appear in /sys
somewhere, perhaps under the name "JP1":
if (gpio_request(QNAP_TS41X_JUMPER_JP1, "JP1") == 0)
gpio_export(QNAP_TS41X_JUMPER_JP1, 0);
Can someone have a look in e.g. /sys/devices/virtual/gpio or some of the
other directories in "find /sys/ -name \*gpio\*" and see if they can
find it?

I wonder if/hope this is something where DT will eventually help us.
Looking at the qcontrol source it doesn't seem to have any knowledge of
the individual fans, it just has a single fanspeed command.
