Is An AIO Water Cooler Really Better Than An Air Cooler?

Introduction

AIO water coolers take advantage of the heat transfer capability of water-based coolants. They extract heat from copper water blocks much more efficiently than air. If AIO water coolers are better, then why are air coolers still on the shelves of computer hardware stores? To truly understand how both of them have their specific role and advantages, we need to dive deeper into the physics, installation, and economic aspects of coolers.

CPU cooler manufacturers utilize the thermal capacity of water-based coolant inside AIO units, which makes them compact. They also utilize the simplified construction of air coolers to offer affordable cooling solutions. This article will help you completely understand the key differences between the two types of coolers. By the end, you can make an educated purchase decision based on your personal PC requirements.

Air Cooler for Simplicity

Air coolers are popular amongst gamers and especially in budget builds for productivity. They are easy to set up and mostly come preassembled with brackets to match your CPU size. Let's analyze its mechanism, parts, advantages, and some popular Air CPU coolers to kick-start your knowledge journey.

Cooling Mechanism of an Air Cooler

Air coolers are simply large pieces of metal that sit on top of the processor. The body of the air cooler is thermally bonded to the CPU. The part that comes in contact with the air cooler base is the integrated heat spreader (IHS). A thin layer of thermal paste is applied to fill the microair gaps between the IHS and cooler base. The body of the air cooler, including the fins, heats up. A fan is installed over the fins to forcefully move cool air over them, which takes the heat from the fins and becomes hot air at the other end of the fin.

The mechanism creates a cooling effect that keeps the processor cool. However, the air inside the chassis is heated. The inside air is then forced out using fans installed at the back. Fresh cool air enters from the mesh in front, bottom, or top of the pc and the cycle continues.

Parts of an Air Cooler

What makes an air cooler gives us deep insight into how they are advantageous for some users. There are a total of 5 main parts:

• Heat Spreader Base: It is the part that comes in contact with the CPU IHS. It has heatpipes passing through the block, either soldered or mechanically press-fitted into the whole block. They can also be direct contact or indirect contact with the IHS. The best is soldered with indirect contact.
• Heat Pipes: These are typically tubes of copper with a vacuum inside them. They are filled with water or ethanol. When the base heats up with the processor, it heats up the pipe instantly, evaporating the liquid, causing it to move upwards, where it is cooled by fins.
• Heat Sink Fins: They are like large thin plates attached to the heat pipe to take its heat and spread it over their large area for heat transfer.
• Fan: The fan then forces cool air onto the large fins, creating the cooling effect that goes to the process.
• Mounting Mechanism: These are brackets that make the cooler fittings compatible with your CPU socket.

Advantages of Air Coolers

Air coolers are popular amongst gamers with a mid-tier gaming rig or a budget build. These cost less than the liquid coolers and sometimes outperform them with certain advantages:

• Simple Build: The whole air cooler unit comes as one, which makes it easy to assemble and disassemble.
• Cost to Performance Ratio: They come in 30W heat removal capability (Thermal Design Power) to 280W+ cooling capacity, with almost 3x price difference to liquid coolers with the same TDP.
• Reliable: Due to fewer moving parts, they are less prone to failure
• Compatible: They are compatible with modern CPU chipsets. Also, they can have brackets to fit the processor conveniently.
• VRM Cooling: The movement of cool air inside the chassis causes the nearby components to cool. The voltage regulating module of the motherboard is the most cooled, making the motherboard run more stably and longer.
• Leak-Free: There are zero chances of leakages as the whole assembly is metal, which is hard to damage.

AIO for Performance

When we are aiming for performance-oriented CPU builds and gaming PCs, we need AIO units. These are extraordinary when it comes to heat removal capability. Their inherent physical property of using liquid for cooling makes them superior in performance.

Working Phenomena of AIO Cooling Units

We will start from the heat source, which is the CPU. A water block sits on top of the CPU and is thermally connected to the IHS. A pump is installed within the water block, which moves liquid over the cold plate. The liquid heats up and moves through the piping to the inlet of the radiator for heat transfer.

Within the radiator, there are metal tubes that carry the liquid from the inlet to the outlet. Within the region from the inlet to the outlet of the radiator, the tubing is fitted with large fins that take the heat from the tubes and spread it over a large area. There are fans mounted on the radiator that force cold air over the fins to cool them. At the outlet of the radiator, cold water moves to the water block, and the cycle repeats.

Parts of AIO Cooler

• Pump: It is the main component that moves the liquid within the closed loop. It creates the pressure difference required in the loop to start flow and overcome the flow restrictions.
• Radiator: It is the part where heat is rejected. It's similar to the heat sink of an air cooler. However, here are static fans which can be in 120 mm or 140 mm in quantities of one, 2, 3, or 4. They have a higher surface area than air coolers.
• Tubing: These connect the radiator inlet and outlet with a water block.
• Static Pressure Fans: These are fans that create high static pressure to move air across the radiator for cooling.
• Coolant: It is the liquid that heats up from a cold plate and moves to the radiator for cooling. It is a high-heat-capacity liquid that can be water-based with additives for enhanced conductivity.
• Mounting Bracket: These are vital to ensure that the water block aligns with the processor at hot spots, depending on the socket dimensions.

Advantages of AIO Coolers

AIO coolers are designed for high-TDP CPUs, which produce lots of heat under operation. Here are the factors that make AIO superior for performance:

• High Heat Removal: Due to the use of liquid with pumps and fans, the capacity of heat removal of AIO coolers is high. They can ramp up speeds to increase heat removal significantly and reduce to near-zero noise levels.
• RAM Clearance: There are no RAM clearance issues like air coolers. The water block sits clear of RAM slots.
• Chassis Air Movement: Radiators may push or pull air from the PC case, which enhances air circulation for component cooling.
• Thermal Mass Stability: As a liquid has a higher heat capacity, it does not rapidly change temperature, causing frequent speed increase and decrease on quick, high-demand processor applications.
• Lightweight for Motherboard: The water block is lightweight, which doesn't put lots of stress on the motherboard.
• Aesthetic: They come with integrated AMOLED or IPS displays for custom messages, logo, system diagnostics, or GIFs.
• Compact: They can fit inside a small chassis and still offer high TDP, unlike air coolers.

Conclusion

We can safely conclude after thorough investigation into the two major categories of CPU cooling that the AIO water cooler is better than an air cooler in performance. However, when it comes to budget air coolers, they take the lead. For our readers, we have the following tips to conclude our comparison:

• Pick an air cooler for a high airflow PC case, a budget build, and a <300 TDP requirement.
• Go for AIO water coolers for compact PC cases, high-end, and >300 TDP CPUs.
