What is i9 9900k Processor?

I9 9900k is a core processor that was launched by Intel in late 2018. It is based on the Coffee Lake (CFL) microarchitecture for high-performance mobile devices and desktops. This processor operates at a 3.6 GHz with a frequency of up to 5 GHz. This core processor helps in delivering smooth streaming of premium 4K UHD entertainment to your PC.

The processor is the main part of the computer. As your work processor produces heat, it is necessary to keep the processor at an optimal temperature that helps you to get maximum output. The best way to cool or maintain the temperature of a processor is by using a liquid cooling system.

What is the Work of the Liquid Cooling System?

The liquid cooling system also is known as a water cooling system that provides a solution for the CPU from protecting it to overheating. As the CPU gets heated due to high-temperature liquid cooling helps to keep the temperature at an optimal level. If you are thinking of whether you need to refill the liquid or not in the system I would say it depends on which type of liquid cooling system you have used. There are some liquid cooling systems that you need to refill it and there are some which you don’t need to refill.

People choose a liquid cooling system rather than an air cooling system because it is quieter. The air cooling system produces noise as it has a fan-based setup but a liquid cooling system silently cools down the processor and protects it from overheating.

What Are the Types of Liquid Cooling Solution?

Generally, liquid cooling solutions can be categorized into three categories. They are:

AIO (All- In- One)

This liquid cooling solution can also be said as closed-loop liquid coolers which are sealed coolers. This type of liquid cooler cannot be refilled but some AIO coolers can be refilled because the water can evaporate through the tubing. But, generally, these types of coolers do not require any maintenance.

Kits

This is the opposite of AIO because you need to build a full loop liquid cooling solution from scratch. There are fewer chances of leaving something as you will get everything in a kit.

Custom Water Cooling

Like kits, you need to do it from scratch but you can customize the loop. You could link the loop from your processor to a graphic card. More advanced customization could link motherboards in the loop.

Factors to be Considered While Buying the Liquid Cooling System

Water or liquid cooling system consists of the following elements

  • A pump
  • A reservoir
  • A heat transfer block
  • Piping
  • A radiator and fan

The size of this type of system will vary from a large external unit to a midsized. To choose over liquid cooling system following factors must be considered

Budget

The first thing you need to consider before your purchase is your budget. Does the cooler fit your budget? This is the first question that arises in your mind before you buy it. An appropriate budget should be allocated to buy the cooler. You cannot spend all of the income in your cooler nor can you spend less and come up with a cooler that is inappropriate for your PC. There are still other factors you need to consider but this is the most important one.

Your Specific Use Case

Based on the workload your processor gets, you need to choose your cooler. If you are thinking of overclocking, you need a high-intensity cooler. High intensive works like video editing, gaming need that type of processor which is a workhorse to keep the temperature at an optimal level.

Air Cooling or Liquid Cooling

This is one of the biggest dilemmas that an individual faces whether to choose air coolers i.e. fan-based setup or liquid cooler. If you have a limited budget and your system does not require extra cooling then you can prefer air coolers but if you have a processor like i9- 9900k which is a workhorse then I would ask you to prefer liquid coolers. Although liquid coolers are expensive but for performing intensive tasks extra cooling is essential which can be provided by liquid coolers. Furthermore, liquid coolers take less space and make the CPU look less messy.

TDP Rating

“TDP (Thermal design power) is the maximum amount of heat generated by a computer chip or component that the cooling system in a computer is designed to dissipate under any workload”- Wikipedia. This is the most important factor to determine whether the cooler suits your system or not. When you buy a processor or cooler, both have a TDP rating. The TDP rating of a cooler must be lower than the processor to perform tasks effectively.

CPU Socket

The manufacturers try to produce a CPU socket in such a type that all the coolers could fit into it. But it is next to impossible so before you buy a cooler you must see whether the cooler could fit the socket or not. So, before buying make sure it is compatible with the processor, motherboard.

Aesthetic Looks

The cooler must be eye-pleasing. The cooler must not look messy when added to the processor. Before purchasing checkout some pictures of the finished processor so that you would choose the right one.

Benefits of Liquid Cooling System

More Efficient than Air

The liquid cooling system is more efficient than the air cooling system because of water’s high thermal conductivity. The liquid cooling system works silently as it does not work on a fan-based setup. Liquid solutions also prolong the lifespan of hardware by ensuring they are being cooled.

Higher Overclocking Potential

Overclocking means pushing your processor or graphics card to perform over its normal clock speed which requires more power. Thus, the processor will be heated. These basic to medium overclocking could be handled by AIO coolers but some processors need an advanced cooling solution like a custom water cooling system to protect their processor.

Occupies less Space

Air cooling systems occupy larger space than liquid cooling systems because the liquid cooling system consists of water blocks and tubes whereas the other one uses a fan-based setup. If you have a high powered processor and graphic cards you will need to install a large air cooling system but liquid cooling systems are small in size and are easy to install.

Suitable for the Environment With High Temperatures

As air coolers use the air of the environment to make the processor cool, if you live in an environment where the temperature is high then it will be difficult for the cooler to cool your processor. But liquid coolers have nothing to do with the temperature of your surroundings as it uses water blocks to cool your processor.

Cooling Specific Components

Air cooling systems could also cool specific components by placing a fan near to them but it could make the CPU look messier. Liquid cooling allows heat removal from the specific components that are also prone to heating such as hard drive, power supplies.

Consequences of Using a Liquid Cooling System

Susceptibility to Leaks

Liquid cooling systems use the liquid to cool the processor therefore, there are high chances of liquid being leaked which may damage the hardware. Furthermore, manufacturers do not agree on any warranty claim on water-based incidents.

Expensive

The expenses to build a liquid cooling system from scratch could range from USD 300 to USD 500. But the complete air cooler cost around USD 100 to USD 200.

Complex to Install

Installing the liquid cooling system requires a certain degree of understanding in the fields of electronics and thermodynamics. It also requires more involvement than installing an air cooler. An air cooler requires a sit atop, a GPU, or CPU or alongside a PC case but a liquid cooler requires connecting tubes and wires, understanding the placement of loops and radiators or fans.

Why Does i9 9900k Need a Liquid Cooling System?

I9 9900k is popular for performing very intensive tasks such as video editing, streaming, etc. During this process, the processor gets heated up due to which it requires liquid cooling. The maximum temperature that it could tolerate is 100 degrees Celsius but the thing is you need to keep it below 80 degrees Celsius even when you overclock it if you want to protect your hardware. The higher the temperature, the lesser its life will be and if it gets too hot then it will throttle down to lower clock speeds to prevent itself from any damage.

Active Cooling Versus Passive Cooling

Active cooling Passive cooling
Active cooling involves the use of energy to cool something

It involves higher financial cost as it requires electricity for the removal of heat

Passive cooling doesn’t use any kind of energy for cooling

It is cost-efficient as it uses natural resources like the wind for the removal of heat

Conclusion

The most important part of your computer is a processor, to protect your processor from any damages due to overheating, liquid coolers are the best. It cools your processor and minimizes the risk of damage. It is very necessary to keep the temperature of the processor at an optimal level. Thus, the liquid cooler helps a lot. It produces noise at the minimum level and works effectively. It is brilliant for the workhorse like the processor i9-9900k. At last, you should keep the cooler for your processor to protect it from further damage by considering the various factors as mentioned above.
