If your board has a ZIF socket with the protrusions for attaching something, you could mount a small s7 HSF. If your board has only 2 of those protrusions (most s7-like CPU sockets have at least 2 or 3 each side) you'll need one of those z-wire clamps.
Otherwise if your CPU (which has its heatsink removed) is flat, perhaps you could use one of those traditional clamp-on HSFs that attaches directly to the CPU (these are mostly 486, pentium ones I haven't seen a lot but do exist).
