Warm Tips
This fan is DC 5V USB powered. Do NOT connect to 12V power supply, wrong voltage will burn out the fan and cause permanent damage.
There will be working noise when the fan runs at 1800 high speed. It is a normal physical phenomenon for high‑speed fans, it is not product quality defect.
Do not block the fan air inlet and outlet, blocked airflow will reduce cooling effect and may cause overheating of fan itself.
Manual measurement may bring minor dimension deviation. Slight color difference may exist due to screen display, please refer to real item.
Keep away from liquid, humid environment and dust accumulation. Regularly clean dust on fan grille for longer service life.
The cooling performance depends on placement way and surrounding environment, it can lower temperature but cannot achieve zero‑heat.
If fan fails to spin, please check your USB power adapter output, insufficient power output may lead to fan not starting.
