Titan TWC-A04 our 1st Mods to improve cooling

" Here we can see that the Titan TWC-A04 in its basic form gives super cooling performance even with the single external fan running at only 7.5v volts and the main unit at the lowest speed for least noise. As we increase the fan voltage hence speed of the external radiator fan the cooling increases proportionally.
