Regarding the mute problem of DC fans, manufacturers who produce Raspberry Pi 3 generations are more or less troubled by this problem. The sound of DC fans is getting louder after half a month, or after a month or half a year, the sound is only It's bigger, and it's pretty good at first. What is the reason? Can the DC fan stay silent for a longer period of time?
The DC fan supplied by Jingyang Tech also had this problem before. After more than half a year of improvement, we replaced the original 3007 male model bearing and shaft core with a special model bearing. The shaft core has higher bearing accuracy. The fuel-saving ability is stronger. In order to keep the fuel longer, the outer frame is changed into an integrated hydraulic fan. The running sound can ensure that the DC fan of the 3007 Raspberry Pi 3 can be used for more than one year without any problems.
For customers with high requirements, Jingyangda can be made into a double ball bearing structure, using ultra-thin ball bearings, waterproof, high temperature resistance, life can reach 50,000 hours
