Problems solved by technology
When the central processing unit is running at high speed, if the temperature of the central processing unit exceeds its normal operating temperature range, the central processing unit is very likely to have an operation error or temporarily fail, which will cause the host computer to crash
In addition, when the temperature of the central processing unit far exceeds its normal operating temperature range, it is even very likely to damage the transistors inside the central processing unit, thus causing permanent failure of the central processing unit

Embodiment Construction
[0026] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:
[0027] Please refer to figure 1 , which is a method for estimating the life of a fan according to an embodiment of the present invention. First, as shown in step S105, a number M of fans to be detected is provided, where M is a positive integer. In this embodiment, the number M of fans is 50, for example. Then, as shown in step S110 , an initial start-up voltage (X volts) of each fan is measured. In addition, this embodiment can also measure an initial current (I), initial rotational speed, and initial noise level of each fan when a voltage of 5 volts is supplied to the fan. In addition, this embodiment can also drive these fans through a power supply or a signal generator in a pulse width modulation (Pulse Width Modulation, PWM) manner, and measure the power generated by each fan to the power supply. an initial response v...

The method for predicating the service life of a fan, comprising the following steps of: providing M fans to be detected; measuring the initial starting voltage (X) of the fans; constantly keeping the fans operating at an experimental temperature, and measuring the starting voltage (Y) of the fans at detection intervals and recording the number of the broken fans and the broken time thereof until N fans are broken, wherein when the starting voltage (Y) of any fan is not less than (X + 0.5)volt, the fan is determined as the broken fan; and emulating the distribution condition of the broken time points of the fans by means of a Weibull distribution model, and calculating shape factors and characteristic factors of the Weibull distribution model in order to calculate the service life value of the fans at the experimental temperature.
Description
technical field [0001] The invention relates to a method for estimating the life of a product, in particular to a method for estimating the life of a fan. Background technique [0002] In recent years, with the rapid development of computer technology, the operating speed of the computer has been continuously increased, and the heat generation rate of the electronic elements inside the computer mainframe has also been continuously increased. In order to prevent the electronic components inside the computer host from overheating, resulting in temporary or permanent failure of the electronic components, a heat dissipation module is placed inside the computer host in the prior art to dissipate the heat generated by the electronic components outside the computer host . [0003] Among these electronic components, the central processing unit (CPU) is the main source of heat generation in the electronic components of the computer host. When the central processing unit is running ...
