[AI Notes] Why Does AI Require Liquid Cooling in Data Centers?

 As artificial intelligence continues to advance, one technology is receiving increasing attention:

Liquid cooling.

Traditional data centers have mainly relied on air cooling. However, modern AI servers generate significantly more heat, raising an important question:

Why do AI servers need liquid cooling instead of traditional air cooling?

Why Do AI Servers Generate So Much Heat?

Training and running large AI models require massive computational power.

Modern AI GPUs perform enormous numbers of calculations, and high-end GPUs can consume hundreds of watts to more than 1 kilowatt of power each.

A single AI server may contain multiple high-performance GPUs.

The more electrical power a system uses, the more heat it generates.

Why Is Air Cooling No Longer Enough?

Traditional servers use fans to move air and remove heat.

However, AI servers have become increasingly dense, with more powerful GPUs packed into smaller spaces.

This creates several challenges:

  • Higher heat generation
  • Limited airflow efficiency
  • Increased cooling requirements

If heat is not properly managed, it can lead to:

  • Reduced performance
  • Lower system stability
  • Shorter hardware lifespan

How Is Liquid Cooling Different?

Liquid can transfer heat much more efficiently than air.

Liquid cooling systems place cooling materials closer to high-heat components, especially GPUs, allowing heat to be absorbed and transported away more effectively.

Compared with air cooling, liquid cooling can help AI servers maintain high performance more consistently.

Benefits of Liquid Cooling in AI Data Centers

Liquid cooling is not simply a way to make servers colder.

It can provide broader advantages at the data center level:

  • Enables higher computing density
  • Reduces energy used for cooling
  • Helps maintain stable server performance
  • Improves space efficiency

As AI data centers become larger and more powerful, these advantages become increasingly important.

Why Is Liquid Cooling Becoming More Important?

AI models continue to grow in size, and GPU power consumption continues to increase.

As a result, liquid cooling is moving from a specialized technology toward an important infrastructure component of future AI data centers.

Understanding the AI industry requires looking beyond GPUs.

Other critical elements include:

  • Electricity supply
  • Cooling infrastructure
  • Networking systems
  • Data center design

The future of AI depends not only on smarter algorithms but also on the physical infrastructure that allows them to run.

[Investment Philosophy] Is It Already Too Late to Invest After Good News?

 Every investor has experienced this moment at least once. "A company just announced great news. Should I buy the stock now?" The short answer is: In many cases, the market may have already priced it in. Why Does the Market Move Before the News? Stock prices often appear to move because of news. However, in reality, markets frequently move before the news becomes public. Expectations about: Improving earnings New product launches Industry growth Technological breakthroughs Business strategy changes are often reflected in stock prices ahead of official announcements. By the time a headline appears on financial websites saying a stock has "surged," much of the expected information may already be included in the price. Why Can a Stock Fall Despite Positive News? Many investors have experienced this confusing situation: A company announces excellent news. The investor buys the stock. The stock price falls shortly afterward. Why does this happen? It is not necessarily b...

[Clinical Edge] My New Glasses Make Me Dizzy — Should I Keep Wearing Them?

 Feeling dizzy, uncomfortable, or slightly nauseated after getting new glasses is not unusual. Especially when your prescription changes significantly or your astigmatism correction is different, your eyes and brain may need time to adjust to the new visual information. However, not every uncomfortable feeling is simply an adjustment period. How long does it take to adjust to new glasses? For many people, adaptation takes: A few days Up to 1–2 weeks During this period, it may help to wear your new glasses consistently rather than switching back and forth between old and new glasses. If the prescription change is large, you may start by wearing them for shorter periods and gradually increase the wearing time. When should you have your glasses checked again? You should consider returning to your optician or eye doctor if: Dizziness continues for more than 2 weeks Straight lines or objects look tilted One eye feels significantly different from the other You develop headaches or severe...

[Clinical Edge] Should You Wear Your Glasses During an Amsler Grid Test?

  Yes—if you normally wear reading glasses or near-vision glasses, you should wear them during an Amsler grid test. The goal of the Amsler grid is to detect changes in your central vision , not blurry vision caused by an uncorrected prescription. Performing the test under your usual reading conditions helps you obtain the most reliable results. Why Should You Wear Your Reading Glasses? An Amsler grid is a simple tool used to monitor the health of the macula, the central part of the retina responsible for sharp vision. It helps detect changes such as: Wavy or distorted lines (metamorphopsia) Missing or blurred areas in central vision New blind spots If your near vision is naturally blurry because you are not wearing the glasses you normally use for reading, it can become difficult to tell whether you're seeing a true retinal change or simply an out-of-focus image. For the most accurate results, perform the test the same way you normally read a book or use your smartphone. What If Y...
