Whether you’re using a laptop or a PC, if you listen closely, chances are you’ll hear a small fan humming. This is where liquid cooling comes in.
If your computer has a high-end graphics card and lots of power, you may even hear more than one.
In many computers, fans keep the electronic segments very cool. However, if you need high-end equipment or want to make your PC run faster, the fan probably won’t provide enough power.
If the PC produces a lot of heat, liquid cooling, also known as water cooling, may be the best solution. It may seem a bit counterintuitive to place liquids near sensitive electronic equipment, but water cooling is certainly more efficient than air cooling.
The liquid cooling of a PC works in a similar way to the cooling system of a car. Both use an important principle of thermodynamics, namely that heat is transferred from warmer to colder objects.
When the cooling object heats up, the cooling object cools down. You can experience this standard by placing your hand in a cool place in your workspace for a few seconds. By the time you lift your hand, your palm will be a little cooler, and where your hand was, it will be a little warmer.
Liquid cooling is a very normal interaction. The vehicle cooling system circulates water through the engine, usually mixed with a liquid catalyst.
Water flows from the engine to the radiator, a system of fins and tubes with a large outer surface area.
Heat is transferred from the high temperature water to the cooler, making the water cooler. At this point, fresh water flows into the engine. The cooler heats the air and cools it at the same time. In this way, the engine heat escapes from the cooling system and enters the ambient air.
If the surfaces of the radiators were not in contact with the air and did not dissipate heat, the system would only move the heat instead of dissipating it.
The vehicle engine produces heat as a result of fuel consumption. Some parts of the PC produce heat as a side effect of the moving electrons.
Microprocessors for PCs are equipped with electrical transistors, which are essentially electrical switches that can be turned on or off.
When the state of the transistors switches between on and off, the power of the processor shifts. The more transistors on the chip and the faster they change, the greater the chip noise. Just like an engine, when the chip overheats, it starts whistling.
What is liquid cooling?
Obviously, you should not send water directly into the computer to cool it down. But how does it really work? The liquid cooling of a PC is a bit like a liquid-cooled engine in a car.
The pump sucks coolant from the cylinder block to the radiator. It goes from the heat sink to the room space, and creates a lot of heat. At this point, it returns to storage.
The entire circuit is closed, so nothing can escape from the liquid cooling system. The coolant just goes through the CPU, GPU, or whatever gets hot enough to justify it, and then back to the memory.
The radiator is there to cool the coolant. It is equipped with several fans that direct the hot air away from its metal balances and release the heat into the environment.
Why it is necessary
Computer chips have become much more efficient. GPUs are also on their way to achieving this. Why use liquid cooling now anyway? Some good reasons, actually.
First, liquid cooling cools better than air cooling. Even though the segments are not as hot as they used to be, they are still hot. This is especially obvious if you plan to overclock. Liquid cooling allows for lower temperatures, a difference that is even greater at more extreme loads.
Liquid cooling is more stable than air cooling and is less affected by ambient temperature. On a hot day, even the most powerful air cooling solutions can’t keep up. A fluid circuit would be much better.
Coolant can store more heat than air. In addition, radiators offer a much larger surface area for heat dissipation. Liquid cooling is just better. What would you rather have: a big, ugly radiator that takes up a large part of your shop or a series of plain colored tubes? Believe it or not, it doesn’t take much thinking.
It goes without saying that liquid cooling is aesthetically more attractive and offers even more possibilities for individual design.
Finally, liquid cooling allows the use of larger RAMs. Massive heatsinks regularly limit RAM space on motherboards. The best RAM keys don’t fit under most of them at all. Liquid cooling puts an end to this problem.
Heat sink or liquid cooling
Most PCs dissipate heat using heat sinks and fans. Heat sinks are essentially pieces of metal that form a large surface area in contact with the air. The chip heats the source, the source heats the air, and the fan exhausts the hot air from the PC case.
This system usually works, but sometimes the electronic segments produce more heat than the main airflow can dissipate.
Higher chips with many transistors can overload the air cooling system. Also, chips that are timed or physically configured to operate faster than the default speed.
That’s where water cooling comes in. Water has a higher thermal conductivity than air – it can transport heat faster than air. Water also has a higher apparent thermal limit. It can absorb more heat before it gets hot.
There are two reasons why a PC may require extensive thermal conductivity and water heat mitigation:
- The electronic components produce more heat than the surrounding air can absorb.
- The fans must move enough air to cool each segment, which makes a lot of noise or consumes a lot of energy.
In general, there are two reasons why you should cool your PC with liquid rather than air:
- The components in your PC require more cooling than air alone can provide.
- You need your body to calm down.
AIO vs.custom loop
You’re probably thinking: Unbelievable. I’m off to buy one of those famous liquid coolers. Now, wait a minute. There are some differences there as well. AIO liquid coolers aren’t terrible (in general), but they generally don’t compare to conventional coolers.
AIO liquid coolers are a closed loop system. They’re fixed, so you don’t have to fix anything. AIO coolers are the easiest and cheapest way to do liquid cooling.
AIO coolers are also the smallest common variable in liquid cooling. They tend to use the most accessible and least implausible details. Their cooling performance is therefore regularly compared with that of very high-quality air coolers.
The individual cooling circuits are complete kits. They accompany every danger and every gain. You need to choose the right parts and attachments. It also means you have a universe of possible consequences.
You can make your circuit as big or as small as you like, with as many radiators as you like. You can customize your loop to the specific amount of heat generated by your PC, making it a much more professional cooling solution.
But there is a central location. Some of the companies that make individual parts for individual liquid cooling systems, like Swiftech and EK, are assembling these parts to make increasingly remarkable AIO coolers.
These higher performance AIOs not only use components similar to those of custom loops, but can be customized and upgraded if desired. They provide an overview of the world of liquid cooling and allow you to decide which components to add and move when.
Is the coolant worth it?
The evaluation of liquid cooling is extremely emotional. Liquid cooling is expensive. Estimate the recovery of the loop. In fact, even the simplest custom liquid cooling circuit costs about $200, and that’s extremely important.
Computer chips and GPUs are becoming more efficient, and air cooling systems are generally ready to go. AMD Ryzen processors can even be overclocked to reach the maximum breakpoint of the standard coolers they are equipped with. No liquid cooling is required at this location.
Anyway, liquid cooling is great? You might need this. Liquid cooling is a extra attractive solution and angle to the additional interests of building and modifying a PC. If you enjoy building a PC and want to take it to the next level, liquid cooling may be the perfect solution for you.
If you’re considering liquid cooling to get the most out of your processor, it’s probably best to buy one that’s all the more striking. Presumably, it will be cheaper.
If you’re looking for a powerful cooler for overclocking and don’t need a huge heatsink, consider a better AIO rig. They will solve your problem with minor issues.
