The FPGA does not get hot.
The only chip that gets hot enough to warrant the fan is the power
supply, and only when in the enclosure. The enclosure has the fan
directly adjacent to the power supply chip.
When using the board without an enclosure, the fan is not needed.

I use an early-rev USRP in a thermally-controlled environment. The
USRP is inside an old SCSI disk
cabinet, with a switched PC-style power supply providing power.
There’s a fan in that enclosure.
This whole thing lives inside a styrofoam cooler, surrounded by thermal
mass (a slab of aluminum, and
a bunch of gel-packs).
The equilibrium temperature of this setup hovers around 35C–I have a
temperature probe attached to
the aluminum thermal mass under the SCSI enclosure. That’s not
particularly hot.
