And i will tell you why, not only does it tame APU/CPU temps better than any traditional heatsink/fan assy but it relocates the CPU heat exchanger outside the case which makes for a MUCH cooler running system, no longer is the CPU adding to the heat inside the case, only the GPU, RAM, HDD and Motherboard are left to dissipate heat inside the case and you can always move the drives outside if so inclined but for the price and all the advantages it offers compared to the traditional method you can't go wrong with liquid cooling, just my $.02
