The PCIE device may be applied to an electronic device, and the electronic device may be, for example, a server, a storage device, a computer, or other computing devices. The PCIE device includes a DPU, an IPU, or an SNIC card, where, when the server is in a shutdown mode, the PCIE device such as the DPU, the IPU, or the intelligent network card needs to provide an NCSI function, so as to provide the server with an out-of-band management network continuously. In the prior art, power is supplied to PCIE devices in a power-off mode by modifying a power supply logic circuit on a motherboard of a server.

Because the power consumption of the PCIE device DPU, IPU or SNIC is generally larger, the power consumption is tens of watts to 100 watts, and the PCIE device generates heat during operation, in order to solve the heat dissipation problem, the PCIE device is usually cooled by the continuous operation of the chassis fan. Therefore, in the shutdown mode, power is supplied to the PCIE device to waste energy; the case fan needs to continue to run to radiate heat for the PCIE device, which also wastes energy and generates noise; in order to use the NCSI function of the server, the power supply logic on the motherboard of the server needs to be modified significantly; the power logic of the fan also needs to be modified to be used in the shutdown mode.

The second scheme provides a method for actively radiating heat by using a self-contained fan for PCIE equipment. In order to solve the heat dissipation problem, a fan is arranged on the PCIE equipment, and active heat dissipation is performed by using the fan.

The second scheme also has the problems that the power supply logic circuit on the main board of the server needs to be greatly modified, energy is wasted and noise is generated, and the active heat dissipation scheme is adopted for heat dissipation through the board card, such as the adoption of a self-contained fan, so that the energy is wasted and the noise is generated.
