Thermaltake BigWater 760Plus, the new 2U drive bay liquid cooling system, is designed for advanced LCS lovers. Ultra quiet pump, 12CM blue LED fan (fan speed from1600~2400 RPM) and water reservoir are all strategically positioned inside the drive bay unit to achieve maximum performance and extreme space saving! In the meantime, the P500 pump pushes 500L/H of water to improve the overall cooling efficiency and performance level; the Dimple Tube Technology of the radiator increases the turbulence within the radiator to enlarge the coolant contact surface and extend the time coolant stay in the radiator to perform maximum cooling action.
