Iceman radiators have higher cooling efficiency and lower noise levels. According to test data, Iceman radiators have a stronger cooling capacity than Leeman radiators, which can lower the temperature of your equipment more effectively. In addition, Iceman cooler adopts advanced fan design and heat sink structure, which can reduce noise generation and provide a quieter usage environment. In contrast, the Leeman radiator is relatively weak in terms of cooling effect and noise control. Therefore, all things considered, the Iceman radiator is better.
