The invention relates to a fan cooling control system based on NRF 905 non-contact temperature acquisition. The control system comprises a temperature acquisition and fan control device and wireless data receiving and uploading device. The temperature acquisition and fan control device arranged at a heating part of a cabinet consists of a first housing (105), a first processor (110), a first liquid crystal display screen (108), an infrared temperature sensor (103), a fan (104), and a first NRF905 wireless transceiver module (107), wherein the first processor (110), the first liquid crystal display screen (108), the infrared temperature sensor (103), the fan (104), and the first NRF905 wireless transceiver module (107) are connected with the first housing (105) fixedly. The wireless data receiving and uploading device arranged at a monitoring room far away from the cabinet includes a second housing (201), a second processor (207), a second liquid crystal display screen (205), and a second NRF 905 wireless transceiver module (204), wherein the second processor (207), the second liquid crystal display screen (205), and the second NRF 905 wireless transceiver module (204) are connected with the second housing (201). Compared with the prior art, the fan cooling control system has the following advantages: the non-contact temperature sensor is used for obtaining the temperature of the target device and the ambient temperature and the fan can employ a heat radiation way based on the collected temperature, so that an over-heating problem can be solved and heat exchange can be promoted.
