Chill Vibes: Mastering PC Cooling with AIO Coolers

by PC BUILD JAPAN 2023年11月9日

An all-in-one (AIO) CPU liquid cooler is a cooling solution designed to dissipate heat from your computer's CPU more effectively than air cooling. It consists of a closed-loop system that typically includes the following components:

1. Radiator: The radiator is a heat exchanger that helps dissipate heat. It's usually made of aluminum and comes in various sizes, such as 120mm, 240mm, 360mm, or 480mm, to accommodate different cooling needs.

2. Coolant: AIO coolers use a special cooling liquid (often a mixture of distilled water and additives like anti-corrosion and anti-algae compounds) to transfer heat away from the CPU to the radiator.

3. Pump: The pump is responsible for circulating the cooling liquid through the system. It's typically integrated into the CPU cooling block or situated on the radiator. The pump maintains a continuous flow of liquid to ensure efficient heat transfer.

4. CPU Cooling Block: This is the part of the AIO cooler that makes direct contact with your CPU. It contains a cold plate (usually made of copper) that draws heat away from the CPU. The cooling block is connected to the pump and has thermal paste applied to ensure optimal thermal contact.

5. Tubing: Flexible tubing connects the CPU cooling block to the radiator. It allows the cooling liquid to circulate through the system while maintaining a closed loop.

Here's how an AIO CPU liquid cooler works:

The CPU block makes direct contact with the CPU heat spreader, which is the metal lid on top of the CPU chip. The thermal paste helps ensure good thermal conductivity between the CPU and the cold plate.
As the CPU heats up during operation, the CPU block absorbs this heat, transferring it to the coolant.
The pump circulates the heated liquid from the cooling block to the radiator.
In the radiator, the cooling liquid passes through a series of thin tubes and fins. Air from the case or an attached fan(s) blows across these fins, dissipating the heat from the liquid into the surrounding air.
The now-cooled liquid returns to the cooling block to absorb more heat from the CPU, and the cycle repeats.

This closed-loop system continuously moves heat away from the CPU and dissipates it into the air, effectively cooling the processor. The efficiency of an AIO CPU liquid cooler often depends on factors like the radiator size, the quality of the pump, the fans used, and the effectiveness of the cold plate. AIO coolers are popular for their almost zero maintenance and efficient cooling performance, especially in systems where space constraints may limit the use of larger air coolers.
