Abstract
The present invention provides a heat-dissipating fan with a manually adjustable speed-setting function by locating a speed-adjusting revolving-button or push-button in one of the bolt-holes of the front side or rear side of said heat-dissipating fan. The size, and structure of the regular original heat-dissipating fan is therefore unchanged and a speed-adjusting revolving-button or push-button is provided in a selected bolt-hole for users to set the speed of the fan directly according to needs at any time. Additionally, a temperature-detecting thermal resistor is included to achieve 2-fold speed-adjusting.
