Abstract: An alerting method for fan failure first reads a target value of rotating speed of a fan motor. Predetermining values of each parameters of the fan motor is calculated according to the target value of rotating speed of the fan motor. If a current value of rotating speed of the fan motor is lower than the target value of rotating speed of the fan motor, the failure recorded in a counter is added one time. If a current peak value of the fan motor is higher than a first predetermining current value, the failure recorded in the counter is added one time. If the duration of the current which is higher than a second predetermining current value of the fan motor is higher than a predetermining duration, the failure recorded in the counter is added one time. An alarm signal is sent if the failure recorded in the counter is larger than a predetermining time.

Abstract: The present invention relates to a connector assembly structure of a terminal used for converting connecting wires. A terminal base is disposed on a frame of a cooling system, and the terminal base has a socket into which a first connector is inserted. The first connector is connected to the connecting wires that are connected to a stator of a motor, and has at least one hook on the periphery thereof. The socket has a releasing hole that corresponds to the hook and engages with the hook so that the first connector is detachable. Additionally, a second connector is adjacent to the first connector, and is connected to the connecting wires to be converted. The electrically interconnection between the first connector and the second connector can satisfy the requirement of converting various connecting wires.

The cooling system has a releasing hole that corresponds to the hook and can be engaged with the hook. As a result, the second connector is secured at a fix position, and has an advantage of being detached fast by utilizing the releasing hole. Thus, this invention can satisfy the requirement of converting various connecting wires fast and easily.

Abstract: The present invention discloses a network interface card, adapted for connecting to an electronic device, comprising: a button; an interface, for coupling to the electronic device; a storage device, for storing a connection information and a connection program; and a network receiving module, connecting to the interface, the storage device and the button, for establishing a connection between the electronic device and an external network server through the interface; wherein, by pressing the button before the connection is established, the network receiving module is activated to execute the connection program enabling the connection information to be transmitted to the external network server for gaining the authorization of establishing the connection from the external network server, and by pressing the button after the connection is established, the connection is disconnected.

Abstract: A fastening device for attaching a heat sink to a heat producer, which is supported on a board having through-holes aligned with mounting holes of the heat sink. The fastening device includes a tube adjacent to one mounting hole, a fastening member movably received in the tube, and an elastic member fitted around the fastening member. The fastening member has an enlarged resilient head, a shoulder and a neck extending between the head and the shoulder, with the head adapted to squeeze through the mounting hole and the through-hole for engaging with a side of the board opposite to the tube. The elastic member includes a minimum diameter section fitted around the heck and abutting the shoulder of the cylinder, a maximum diameter section abutting a distal end of the tube, and an intermediate diameter section stretchable between the minimum and maximum diameter sections.
