Problems solved by technology

The general method for testing the fan cooling performance of the product is to set the fan to manual mode through the ipmi command first when the machine is running normally, then set the fan duty cycle to drive the fan to run at a specific speed, and then read the fan duty cycle and speed, verify that the duty cycle is consistent with the setting, and verify that the speed is consistent with the speed range corresponding to the duty cycle. This method can only verify the availability of the fan, and cannot verify the cooling performance of the fan under dynamic conditions, especially high temperature and high load conditions.

Embodiment Construction

[0015] The content of the present invention is described in more detail below:

[0016] The present invention is used in the PC / server production test inspection process, which ensures product quality, improves test efficiency, test coverage and test automation level, and is specifically implemented as follows:

[0017] 1) Under normal room temperature conditions, in the power-on state, read the CPU temperature and fan speed through the ipmi command at intervals and record them in a file named with the machine serial number as the key information.

[0018] 2) Under normal room temperature conditions, the CPU stress test, memory stress test, and hard disk stress test are carried out. During the stress test, the CPU temperature will rise, and the CPU temperature and fan speed are read and recorded through the ipmi command at intervals. In the file named after the machine serial number as the key information.

[0019] 3) Under the condition of high temperature in the aging room,...

Abstract

The invention provides a dynamic server fan heat dissipation performance test method and belongs to the technical field of fan heat dissipation performance test. The method is characterized by, under starting-up and normal operation condition, room temperature pressure test condition and aging room high-temperature environment pressure test conditions, carrying out dynamical multipoint acquisition of CPU temperature-fan rotating speed, drawing a curve, and comparing the curve with a heat dissipation curve to check the fan heat dissipation performance. The method ensures the product quality through analysis of the fan heat dissipation performance, and improves test coverage and test automation level.

Description

technical field [0001] The invention relates to a heat dissipation performance test technology of a fan, in particular to a dynamic server fan heat dissipation performance test method. Background technique [0002] In the current mass production of products such as PC / server, the requirements for product test automation, test efficiency and test coverage are extremely high. The general method for testing the fan cooling performance of the product is to set the fan to manual mode through the ipmi command first when the machine is running normally, then set the fan duty cycle to drive the fan to run at a specific speed, and then read the fan duty cycle and speed, verify that the duty cycle is consistent with the setting, and verify that the speed is consistent with the speed range corresponding to the duty cycle. This method can only verify the availability of the fan, but cannot verify the cooling performance of the fan under dynamic conditions, especially high temperature an...
