T.O.P (Thermal Obviation Protection) represents MSI’s cutting edge technology in designing the new-generation copper cooler especially for Ti4200-8X and Ti4600-8X graphics cards. For general users, the cooling performance and the silence are two key requirements of a high-quality VGA cooler, also called Fan-sink. The cooling performance is directly related to the stability of the new-generation GPU (Graphics Processing Unit) and prevents from overheat when overclocking. On the other hand, as the GPU is becoming more complicated and powerful, the silence of a qualified VGA cooler is more important than ever because the total system cooling requirement and noise is getting higher.
The major benefits that TOP copper cooler can deliver are as follows:
1. Compared to NVIDIA's reference cooler, MSI's TOP tech cooler can control the thermal by 8.8 °C less at Ti4200-8X and 9.7625 °C less at Ti4600-8X.
