Lots of graphics cards use a finned processor heat sink and a small fan - a smaller version of that found on the motherboard.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps).
