Answered: How Long Does An AIO Liquid Cooler Last?

Learn about the lifespan of AIO liquid coolers to keep your PC running smoothly and prevent overheating issues.

Expert Verified By

An AIO cooler is a liquid cooler that helps you stabilize your CPU temperature by relying on liquid solutions. It uses a closed-loop system to pump water or any other fluid to cool your CPU block. However, just like any other component, it gets old as well. Therefore, find out how long an AIO cooler lasts so you can replace it timely.

Key Takeaways

  • AIO coolers can last up to 7 to 10 years if used with care.
  • Maintaining your AIO cooler and monitoring its performance is important for longevity.
  • Replace the AIO cooler if you see air bubbles or leakage.

An AIO cooler typically has a lifespan of about 5 to 7 years, with some lasting up to 10 years, depending on build quality and maintenance[1]. Leading brands like Corsair and Cooler Master offer 3 to 5 year warranties for their liquid AIOs.

Brand Verifications

Mentioned below are the warranties of some of the well-known AIO series:

  • Corsair Hydro Series: 5 years.
  • Corsair Hydro X Series Core (blocks, pumps, and radiators): 3 years.
  • NZXT Kraken Z Series: 6 years.
  • NZXT Kraken X Series: 6 years.
  • Cooler Master’s Master Liquid PL Series: 5 years.

Factors Affecting Its Lifespan

AIO coolers usually last longer than any other custom liquid cooling solution. However, certain factors may decrease their lifespan.

Installation Problems

The most common mistake users make while installing an AIO is placing the tubing beneath the cooling block and radiator, which leads to bubbling noises and poor rotation of the liquid. It causes massive cooling problems and decreases the cooler’s lifespan.

The pump should always be beneath the radiator, not even on the same level, as it ensures the proper flow of the liquid.

Pump Failure

Often, by default, this type of CPU cooler is filled with up to 90% of its total design capacity. This means that 10% of the space is reserved empty. In rare cases, tiny air bubbles can build up in this space, which merge to create bigger bubbles. It occupies the unused space and blocks the outgoing tank.

Luckily, some AIOs offer an extreme mode in their software to remove bubbles, or you can physically bleed the system to let air out if you hear bubbling sounds[2]. This prevents pump issues.


While testing the best 280mm AIO coolers, the reviewer found that most AIO coolers’ radiators, including their fins, are made of copper or aluminium [3]. The thermal performance of copper is better than that of aluminium while lasting much longer because of its resilience and ability to degrade at a lower rate[4].

Copper fins in cooling systems are generally more durable and corrosion-resistant than aluminium fins. Plus, the latter can create a highly oxidising mixture when combined with cheaper welding flux and low-quality coolant. This oxidizing nature can contribute to the deterioration of tubing over time.

Extend The Lifespan Of An AIO Cooler

Here are a few pointers I use to extend the lifespan of my AIO Cooler:

  • Ensure that it is mounted correctly in the direction suggested by the manufacturer.
  • The pump should always be underneath the radiator, and the tubing should remain beneath both.
  • Perform regular maintenance.
  • Prevent dust buildup around the radiator and fans. Although, follow this guide if your AIO CPU fan is not working.
  • Monitor system thermals to confirm proper cooler performance.

Personally, I use Task Manager to monitor the real-time temperature and performance of my AIO cooler. If the fan noise gets noticeably loud, I recommend cleaning it at the earliest. This can be because there’s dust in your radiator or because your cooler is struggling to keep your CPU at ideal temperatures.
