140mm 14cm Computer Case Cooling Fan PC Waterproof Dustproof,2900RPM 140X140X25mm Dual Ball 12V,High Speed IP68 Cooler

TIPS This is the waterproof fan. However, when the fan is powered up in water, the fan cannot run, because the water resistance is more stronger than the power of the fan, but the fan is still good and will not be damaged. When the height of water is 50-70% of the fan, the fan can run.Please watch the video. ENVIRONMENTAL RESISTANCE: IP6X design technology allows this to be completely dustproof and waterproof (rated to be submerged up to 1m for 30min). HIGHER AIRFLOW/LOWER NOISE: Updated blade and motor designs allow this to put out 157 cubic feet per minute with a noise level of 45db. That's equivalent to the ambient noise of nighttime in the suburbs or a standard kitchen fridge. LONG LASTING: Dual ball bearings give a long projected lifespan of up to 50,000 hrs--that's over 4 years. Backed by manufacturer with a 1 year warranty. STANDARD CONNECTOR: Standard 3 pin native connector allows for easy adaptability with many systems.
