CPU Coolers - Factors to Consider When Choosing a Cooling Method

1. Price
The price will vary greatly depending on the prioritized features. However, generally speaking, the cost of air coolers is lower because the operation is more direct. Both have entry-level and advanced versions. The advanced version of the air cooler may be equipped with larger radiators, better fans, and offer different aesthetic designs. High end integrated (AIO) liquid coolers may have a larger heat sink and can be customized in appearance and functionality, such as software for controlling fan speed and lighting.
2. Easy to install
Although the installation of integrated (AIO) liquid coolers is usually more complex than standard air coolers, it is still quite simple. Most of them only include a water cooling head, two hoses for circulating coolant, and a radiator. Additional steps include connecting the water cooling head, which is similar to the process of installing an air cooler, and then connecting the radiator and fan so that excess heat can be easily dissipated from the PC. Due to the fact that the coolant, pump, and radiator are all included in the equipment (hence referred to as "integrated (AIO)"), minimal supervision or maintenance is required after installation.
On the other hand, installing custom loops requires builders to put in more effort and acquire more knowledge. The initial installation process may be more time-consuming, but the increased flexibility allows for more customization, and if necessary, other components such as GPUs can be included in the loop. When implemented correctly, these more complex custom loops can also support various shapes and sizes.
3. Size
Air coolers may have a large volume, but they are limited to one area rather than distributed throughout the entire system. On the other hand, when using an AIO, it is necessary to leave space for the radiator and consider issues such as the correct orientation and alignment of the water cooling head and coolant pipes. That is to say, if the computer is relatively small, an air cooler with a larger volume may not be the best choice. Thin air coolers or integrated (AIO) coolers with small radiators may be more suitable. When planning an upgrade or selecting a chassis, make sure there is enough space to accommodate the selected cooling solution and ensure that the chassis supports the selected hardware.
4. Sound
Liquid cooling, especially when using integrated air conditioning (AIO), is often quieter than fans on CPU heat sinks. Similarly, this is not necessarily the case, as there are air coolers specifically designed to reduce noise, and the setting or selection of fans can also affect the amount of noise generated. But overall, liquid cooling often produces less sound because small pumps are usually well insulated, and the speed of the radiator fan is often lower than that of the fan on the CPU radiator.
5. Temperature regulation
If you plan to do some CPU intensive work, such as rendering videos or streaming, liquid cooling may be the best choice. Liquid cooling is more effective than pure conduction in dispersing heat to a larger convective surface area (radiator), thereby reducing fan speed (better noise reduction effect) or increasing total power. In other words, it is more effective and often quieter. If you are pursuing the lowest possible temperature or interested in quieter solutions, and do not mind slightly more complex installation processes, liquid cooling may be the best choice.
Air coolers are very good at transferring heat away from the CPU, but the heat then dissipates into the chassis, which raises the overall ambient temperature of the system. The liquid cooler transfers heat to the outside of the system through the fan on the radiator, which is done better in this regard.
