PC watercooler - what is an AIO?

An AIO water cooler is a cooling system that keeps a computer's CPU cool by circulating liquid coolant through a water block, tubes, and a radiator.

 

AIO coolers are more efficient and quieter than traditional air coolers. They don't require refilling, making them a low-maintenance option.

 

Overall, AIO water coolers are a good investment for those who want to keep their high-performance computers running at optimal temperatures.
