The heart of the AIO is a small, electrically commutated (EC) pump with a ceramic or metal shaft. ComputerBase teardowns (e.g., of a failed Corsair H100i and an Asus ROG Ryujin) revealed that the most common failure point is not the motor, but the sleeve bearing . After roughly 20,000–30,000 hours of operation (2.5–3.5 years of 24/7 use), the bearing wears down, introducing impeller wobble, increasing noise, and eventually seizing.
