Abstract: A cooling fan with built-in adjustable speed structure of the invention is provided herein. The cooling fan of the invention fan has built-in fan speed controlling parts installed inside, in addition, has a fan speed controlling interface, such as a knob or a keystroke, positioned on the fan frame for a user to directly adjust fan speed as needed without additional wirings to be connected. The invention can be used at any environment where needs a cooling fan.

Abstract: The present invention discloses a structure for fixing a fan with a computer casing, and the structure includes a casing, an opening with a specific area on any side of the casing, and a locking hole proximate to each distal edge of the opening. The interval between two adjacent locking holes is equal to 170±5 mm, such that if a large fan is installed at the opening, a locking member can be secured directly to the corresponding locking hole, not only saving the time of drilling holes, but also resulting no increased area of the casing. The fan can be installed onto the casing for discharging any heat source produced by each component on a motherboard in the casing quickly, so that the heat will not remain in the casing, or drawing outside air into the casing to cool each component in the casing rapidly.

Abstract: A common lead device applied to SATA and periphery power connectors in a computer is described. The device integrates a plurality of power cords output from a power supply into common power cords, by which different voltages are provided.

Abstract: A computer hard drive heat dissipation device for a fixed, swappable or externally connectable hard drive is provided. A heat socket is provided inside a metallic housing, and a heat board is provided on the bottom of the metallic housing. A contact surface where the heat socket and the heat board contact the hard drive, corresponding to a hard drive heat source, is provided with a high heat conductive material or a high heat conductive medium capable of absorbing vibration, enhancing quantitative fit, and conducting heat. The hard drive contact surface and its surrounding space are provided with vibration absorption and sound absorption materials respectively so as to obtain good capabilities in heat dissipation, vibration absorption and sound absorption.

Abstract: Provided with a switching power supply including a built-in chip set so as to control a built cooling fan and or an ambient cooling fan to operate even after the computer system is shut down. As such, the heat built-up within the computer system can be effectively dissipated so as to prolong the service life of the computer.

Abstract: This invention relates to a power supply capable of dissipating heat from computer unit, for enhancing the heat source heat-dissipating effect within the computer unit, including: a blower for exhausting air provided in or above the power supply. The blower is provided with an adjustment knob extended to and provided at an outside of the power supply or computer casing by means of wires. A power terminal of the blower is connected to a backup power of the power supply, where the backup power is controlled by a surrounding temperature monitoring device to operate the blower continuously after shutting off the computer until surrounding temperature has reached a target value.

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.

Abstract: The present invention provides a heat-dissipating fan with manually adjustable speed-setting function, particularly referring to using one of the bolt-holes of the front side or rear side of said heat-dissipating fan without the size, and structure of the regular original heat-dissipating fan changed, and providing a speed-adjusting revolving-button or push-button at that bolt-hole, for users to set the speed of the fan directly according to needs any time, and adapting with the original temperature-detecting thermal resistor to achieve, 2-fold, speed-adjusting.

Abstract: An automatic temperature display and fan rotary speed adjusting device having an operation display panel which is capable of being connected to a disk drive frame, a cover plate or a computer panel. The operation display panel is combined to the computer panel directly, or to the 5.25 inches disk drive frame, or to the 5.25 inches disk drive cover plate, or to the 3.5 inches disk drive cover plate, in each case, the operation display panel is installed with a control circuit board, a thermometer and a connecting terminal connected to a heat dissipating fan. The window is connected to the thermometer. The thermometer is fixed or installed to the hard disk drive, central processing unit or computer. An IC in a circuit board will display the temperature measured by the thermometer and the rotary speed of the fan on the window. A circuit of the fan adjusting button is connected to the circuit board and electric heat dissipating fan.
