Why are water coolers quieter than air coolers?

The main reason why water coolers are quieter than air coolers is because water coolers use water to dissipate heat, reducing the sound of the fan at work. Firstly, the water cooler transfers the heat to the water-cooling head through the water pipe, and then the water-cooling head takes the heat away to dissipate the heat. Air coolers, on the other hand, take the heat away through the fan, and therefore make more noise when they are in operation.

Additionally, water coolers are designed to be more efficient, taking heat away from the CPU or GPU more quickly, which reduces cooling time and noise during operation. In contrast, air coolers can also dissipate heat, but they rely on fans to generate strong air to remove heat, resulting in noticeable noise during operation.

In addition, water coolers provide more precise temperature control because the water cooling system can adjust the working speed of the water cooling head according to the temperature of the CPU or GPU, thus controlling the temperature smoothly and reducing noise. Air coolers, on the other hand, can only control the cooling effect by adjusting the fan speed, which often makes it difficult to be stable and quiet.
