The standard fan cooler used inside computers takes too much space thus limiting insertion of better hardware. One of the methods used to improve computer performance is to use a liquid cooler to prevent overheating. Most current liquid coolers are placed internally, however there is the potential for leaking and extra noise. Our team has designed an external liquid cooling system which means more space for hardware in the computer while avoiding damage caused by leaking. Our cooling system increases the efficiency and security of the CPU.
