Existing systems rely on air to pass heat to a radiator, which then relays heat to the ambient air outside. In order to keep temperatures inside the data centre at sane levels, the cooling water needs to be below ambient temperature, which can be done with either chillers or evaporative cooling. Running a chiller takes a lot of electricity to say the least.
By exchanging heat between the chip and the cooling water directly, it seems they're claiming they can just have a heat exchanger with no chiller or evaporative cooling required. Which is probably true, it's why over clocked gaming PCs are often water cooled.
Why a chiller? You don't need to freeze the servers. If you just use a normal radiator you remove the compressor and just need a pump and a fan
