We hook fans directly to the +12VDC and have them sucking the air over
the logic board on several older Atari games. 12VDC fans are readily
available, cheap, and do not draw much current.
Having a second fan to draw air out the cabinet is a good idea - look
for "Whisper" fans though, regular fans are irritating at low background
noise levels (inside homes).
Do check that the power connections on the logic boards are not
overheating - this would show up as slightly (!) toasted looking edge
connector on the PCB and if present I would jumper (with a plug) to the
wiring harness all the +5 and Ground lines. It will keep your board happy!
Lastly, be sure to check all the ground connections on a XY game to
avoid deflection board damage. Solid ground jumpers between the boards,
power supply and monitor chassis will improve reliability greatly...
