What's the difference between a water cooled 120 and 240? The internet says that there is not much difference in cooling effect, so which one to buy?

1, the length of the difference:

120 and 240 refers to the length of the water cooling water row, water-cooled 120 and water-cooled 240 difference lies in the length of the difference.

2, the cooling effect is different:

The cooling effect is also proportional to the number of fans and the length of the water row.

When buying, you can consider the heat dissipation:

The performance of the radiator plays the most critical role for a water-cooling, and you can even measure a water-cooling with the performance of the heat sink.

Single 12CM heat sink is not enough to meet the needs of today's market 24CM, 36CM radiator has become the mainstream, users can choose different sizes of radiator according to their own cooling needs.

The advantages and disadvantages of water-cooled coolers:

The advantages and disadvantages of water-cooled coolers:

The advantages of a water-cooled cooler include p>

Advantages:

Because the number of fans is reduced, the vibration and noise generated by the fans is also reduced.

The cooling effect is much higher than air-cooled systems.

Disadvantage:

The paraphernalia required for a water-cooled radiator is very large and takes up some space.

The price is higher than air-cooled systems.

Because the structure is more complex than the air-cooled system, and an extra level of workmanship is added, the reliability is also less.

If the assembly process is not careful or when the material is not good, there will be leakage and may damage the computer parts.
