If the demand for air volume is not high, the input voltage of the fan can be reduced by mute, which is immediate. (My 12 and 14cm fans have all dropped to 5V or 7V. )
If you buy it in a retail store, the price ranges from 1x to tens of dollars. These are mainstream products. There will be hundreds of high-end products.
Brand doesn't matter, mainstream products can choose big brands. I'm used to using overclocking three.
