Xu's father and son were born in 2009 and developed the first domestic exhaust notebook cooler that can cool down the CPU by more than 15°C, which can be described as the pioneer of exhaust cooler, and the subsequent improved series has caused a wave of DIY heat dissipation. From manual DIY to mass production, Xu's father and son set up a special studio, improved the production version of the 009 series, and applied for a number of national patents.
 
The latest 009V of Xu's father and son uses an original intelligent temperature control system, with real-time temperature and speed display, automatic and manual speed adjustment modes, and an optimized core fan to provide strong power while reducing noise by 20% compared with the previous generation. The silicone seal can be customized according to the model of the computer, which can maintain good sealing performance and heat resistance. Due to the use of high-power turbine fans, the maximum speed is about 6000rpm in high gear, so there will still be relatively obvious wind noise, and it is recommended that players choose the appropriate gear and speed according to the use scenario and actual cooling needs.
 
In addition, when purchasing an exhaust radiator, consumers had better communicate with the merchant in advance to determine the compatibility of the radiator with their own notebook, and give priority to the model with external power supply, the air volume of such products is more guaranteed.
