Faulty cooling is often noticeable due to an overheated CPU and a cold radiator at the same time. When the pump is still at a standstill, it is time to analyze the inner workings more closely. A lot can come to light that shouldn’t actually be in a water cooling circuit. Deposits, clogged passages and dirty coolant. The problems that can arise in an AiO seem diverse.
Many of the problems are due to the use of two different materials in a water cycle: copper and aluminum. A combination that causes corrosion of the aluminum due to the base aluminum and the noble copper. Although the manufacturers want to prevent this with water additives, all kinds of deposits arise in the system. Before a defective AiO is thrown away or replaced, however, there is nothing to be said against opening the closed circuit and servicing the system. Dismantling, cleaning, rinsing and refilling are often easier than expected. If you get to work with a little patience, you can significantly extend the service life of your cooling system or even breathe new life into your broken water cooling system.
