Very good. However, I thought they were more powerful.

Three weeks prior to the trip to Krasnodar, the price was 17 dollars for three items, and one of those items, a valve, came with a box.

This is a high-quality product that functions well, operates silently, and features impressive RGB lighting effects.

These fans are great, with good quality and excellent airflow. However, they are advertised as having a 4-pin to 12v connector, but they actually have a 4-pin molex with two wires. This means, as anticipated, that the lights are always on in a single mode and are connected directly to the power supply, operating continuously at the same power level.
