Malaysia’s Data Centre Boom Has a New Challenge — Keeping AI Servers Cool

September 28, 2026

Malaysia’s fast-growing data-centre industry is facing a new challenge: heat. As AI servers become more powerful, cooling them requires increasing amounts of electricity. Data centres reached a record 9.3% of Peninsular Malaysia’s electricity consumption during one week in August, putting energy efficiency and advanced cooling technology under greater focus.

Key Takeaways
  • Data centres accounted for a record 9.3% of Peninsular Malaysia’s electricity consumption during the second week of August 2026.
  • The 2026 average before that spike was about 7%.
  • Hot weather increased the amount of electricity required for cooling.
  • The Energy Commission estimates data centres could account for as much as 31% of Peninsular Malaysia’s electricity demand by 2035.
  • AI and high-performance computing are increasing the amount of heat produced inside each server rack.
  • Technologies such as liquid cooling, immersion cooling and AI-controlled cooling systems are becoming more important.

AI Servers Are Getting Hotter

Malaysia has attracted billions of ringgit in cloud and data-centre investment.

But AI is changing what goes inside these facilities.

Traditional servers may consume a few kilowatts per rack.

Modern AI infrastructure using powerful GPUs can require tens of kilowatts or more per rack, generating far more heat in a much smaller space.

That heat has to go somewhere.

And in Malaysia’s hot and humid environment, removing it requires significant energy.

Hot Weather Makes the Problem Worse

The Energy Commission said data centres reached 9.3% of Peninsular Malaysia’s electricity consumption during the second week of August, compared with an average of around 7% earlier in 2026.

Energy Commission CEO Siti Safinah Salleh said hotter weather meant cooling systems needed more electricity.

The problem was made worse by lower water levels reducing hydroelectric generation during the same hot period.

So warmer weather creates pressure from both sides:

Data centres need more electricity for cooling, while some electricity generation can also become less available.

Traditional Air Cooling May Not Be Enough

Most conventional server environments use air conditioning and fans to remove heat.

That works well at normal server densities.

But AI hardware is much more power-dense.

Operators are therefore exploring technologies such as:

  • Direct liquid cooling
  • Immersion cooling
  • AI-controlled fan systems
  • Computational airflow simulation
  • More efficient mechanical and electrical systems

Immersion cooling, for example, places computer equipment inside a non-conductive cooling liquid rather than relying mainly on air.

The objective is simple:

remove more heat while using less electricity.

Malaysia’s Power Demand Will Keep Growing

The challenge will become larger if Malaysia continues expanding data-centre capacity.

The Energy Commission estimates that data centres could eventually consume as much as 31% of Peninsular Malaysia’s electricity demand by 2035.

Malaysia also expects to need around 9 GW of additional gas-fired generation capacity by 2032 as electricity demand grows while coal plants are gradually retired.

Officials have said the current situation does not indicate an immediate electricity shortage.

But longer-term planning is becoming much more important.

Cooling Is Becoming a Business Opportunity

This challenge also creates a new technology market.

Data centres will increasingly need companies that can provide:

  • Efficient cooling systems
  • Energy monitoring
  • Environmental sensors
  • AI-based optimisation
  • Power management
  • Renewable energy integration
  • Infrastructure monitoring

For Malaysian engineering and technology companies, data-centre growth could therefore create opportunities far beyond selling servers or network equipment.

Why This Matters

Malaysia wants to become a major regional hub for AI and cloud computing.

But attracting the servers is only one part of the equation.

Those servers need:

electricity, cooling, water, connectivity and reliable infrastructure.

If Malaysia can make its facilities more energy-efficient, it can support more computing capacity without increasing electricity demand at the same rate.

That could become an important competitive advantage as other countries face similar energy constraints.

Closing Thoughts

The AI boom is creating an unusual challenge.

The faster our computers become, the harder they are to keep cool.

For Malaysia, the next phase of the data-centre boom may therefore be less about simply building more facilities — and more about making every megawatt of computing power work more efficiently.

Cooling may not sound as exciting as AI.

But without it, the AI servers cannot run.

Frequently Asked Questions About Malaysia’s Data Centre Cooling Challenge

  1. How much electricity are Malaysian data centres using?

    They reached a record 9.3% of Peninsular Malaysia’s electricity consumption during the second week of August 2026, compared with an average of around 7% earlier in the year.

  2. Why do AI servers need more cooling?

    AI processors such as GPUs use significantly more electricity and generate more heat than conventional servers, particularly when many processors are installed closely together.

  3. Could data centres cause an electricity shortage?

    Officials have said there is no immediate shortage expected, but Malaysia will need additional generating capacity and careful grid planning as demand continues increasing.

  4. What is immersion cooling?

    It involves placing servers or computing components inside electrically non-conductive liquid that absorbs heat more efficiently than conventional air cooling.

  5. Why is cooling especially important in Malaysia?

    Malaysia’s tropical climate means higher ambient temperatures can increase the amount of energy required to keep computing equipment within safe operating temperatures.
