Titan TWC-A04 7.5 volt water pump mod to increase the cooling performance
 

We think our graph ABOVE shows it all. Increasing the Titan TWC-A04 water pump voltage to about 7.5 volts gives a substantial increase in cooling performance such that it is now in-line with the other water cooled heatsink systems tested here.
