I. Maintenance
The water-cooled radiator needs to change the coolant regularly, which may be troublesome for some users. Air-cooled radiator is much simpler, just need to clean the dust regularly. Pay attention to this when using it.
Second, noise.
The fans of some air-cooled radiators are very noisy and even interfere with other sounds of the computer. But the water-cooled radiator is different, and the noise during operation is like a whisper.
Third, performance.
Water-cooled radiator is an expert in dealing with high-power heat source! I once owned a high-end gaming computer. Even if I play a big game for several hours, the CPU temperature can be kept low-key and it is easy to avoid overheating.
