This is an all-in-one solution that works similarly to air coolers. It works on the same principle as custom water cooling kits. There should be a radiator connected to the top or front of your case, fans to distribute heat from the radiator, a metal block installed on your CPU socket, and the liquid cooling solution flowing around the cooler with the aid of a pump. However, the AIO cooling water solution is simpler than that. It has no coolant reservoir and does not pipe on the case, as it comes with sleeved tubing going to and from the CPU and radiator. The tubing is factory sealed and filled. This means that it does not require any maintenance and protects it from leaks. This cooling solution is budget-friendly.
