Case Fans: Draw in at the front. Expel air at the back.
CPU & GPU Fans: Draw air through the Heatsink Fins and up through the fan, taking the hot air away.
Be aware: Some GPUs, which have fans and heatsinks enclosed in a Case, can suffer from the Heatsink Fins being blocked with dust, invisible underneath the casing. Blowing air in the opposite direction to the fan's pull, sometimes works, otherwise it would be necessary to remove the casing
