120mm 3000RPM Fan Cooling with Controller 12cm 12V 220V Btc Machine Chassis Workstation Cabinet Radiator Server Fan

I purchased it for window ventilation purposes, and it's convenient to use because the airflow can be adjusted.
Even though it is a low-priced fan, the noise level is quite low.
Compared to other brands' exhaust fans, the design is not impressive, but the price range and adjustable airflow are worth considering.
That's quite an advantage.

When I asked AI, they said that it has more airflow than the tabletop circulator used for ventilation. For fans, a tabletop circulator might be more suitable, but for ventilation, this product seems good.

Good product. I am glad i purchased this product. This is exactly what i needed for my project. Thank you for your honesty.. Delivery on time.

It seems that it can be used in various situations. It can be a window-type ventilation fan, and with a little modification, it can also be used as a car ventilation fan for camping. I am satisfied.

It cools my battery to a constant 26 degrees.
