My AIO failed constantly until I switched to a tower cooler and learned the real difference

A PC builder shares their experience with repeated AIO liquid cooler failures over several years, ultimately switching to a tower air cooler. The author argues that AIOs are harder to install, prone to pump failure, expensive to replace, and disruptive to workflow when they fail. Tower coolers like the Noctua NH-D15 are presented as more durable, cost-effective alternatives that can match or rival 240mm AIOs in thermal performance for typical consumer CPUs, with far fewer reliability concerns.
