A thermal module and method for controlling heat-dissipation wind amount thereof is provided. The thermal module is figured in an electronic apparatus having a first heat source and a second heat source. The thermal module includes at least a first wind outlet, a second wind outlet and a first wind-amount adjuster. The first wind outlet is for providing a first wind amount to the first heat source while the second wind outlet is for providing a second wind amount to the second heat source. The first wind-amount adjuster, disposed at the first wind outlet, is for adjusting the first wind amount according to temperature of the first heat source and the second heat source.
