The following is the evaluation of water-cooled mobile phone radiator (68 yuan), graphene mobile phone case (78 yuan), ice-sealed cooling back clip (179 yuan) and small fan (30):

1, first of all, graphene mobile phone case, not only does not have any cooling effect, the temperature does not drop, the price in 78 yuan is really not recommended;

2. The effect of small fan is better than that of graphene mobile phone case. Although the temperature drop is not large, it is at least useful. If you only have it at hand, you can use it to cool down.

3, ice cooling back clip, the cooling effect is no problem, but because it is relatively heavy and large, it will affect the operating experience when it is clamped on the mobile phone. In addition, many people are worried that such a low temperature will cause condensation water inside the mobile phone and damage the original equipment;

4. The water-cooled mobile phone radiator is the most useful one found in this test. The temperature is kept very stable, and the mobile phone is not heavy after being worn, and the water-cooled air outlet at the back will not affect the operation. Its only problem may be that it's a little hard to carry because of its strong sense of playing games, but if you pursue heat dissipation, it's no problem to choose it.
