Don't You Wish Your Data Center Was Hot Like Mine?

In the data center industry, traditional wisdom once dictated that cooler temperatures are better for equipment longevity and efficiency.  This belief led to facilities being chilled to icy levels, even though it consumes massive amounts of energy.  However, the industry continues to dispute this mindset, and many data centers are getting "hotter"—not in terms of overheating, but in optimizing their temperature controls to improve energy efficiency and sustainability.

The Rise of Hot Data Centers

Once upon a time, data centers were maintained at temperatures in the range of 64-70°F (18-21°C) to ensure server performance and hardware longevity.  But overwhelming research from groups like ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) has shown that servers (including prior to the year 2000) can safely operate at higher temperatures—up to 80.6°F (27°C)—without increased failure rates.  This shift in thinking is leading to a "hotter" approach to data center management, allowing facilities to raise their temperatures and significantly reduce cooling costs.

The appeal of this approach is twofold:

  1. Energy Savings: Cooling is one of the biggest consumers of power in a data center, making it a major target for optimization. Raising the temperature reduces the need for constant cooling, resulting in lower energy usage and reduced costs. Some facilities have reported savings of up to 4-5% in energy costs for every degree Fahrenheit increase in server room temperature.
  2. Sustainability: With the global push for greener technologies and reduced carbon footprints, data centers are under pressure to become more environmentally friendly. Increasing server temperatures can drastically cut down on the energy required for cooling systems, aligning with sustainability goals while maintaining operational efficiency.

The Case for Even Hotter Operating Temperatures

The most common motivation for increasing data center operating temperatures is energy efficiency.  Cooling accounts for a significant portion of a data center's power consumption, and the cost of keeping server rooms cold is a major operational expense.  For every degree that a facility raises its temperature, cooling energy use decreases by around 2-5% (depending on the cooling systems).  As such, raising the operating temperature to 90°F and higher can lead to dramatic savings, potentially reducing overall energy consumption by up to 20-25%.

In addition to cost savings, higher temperatures align with global sustainability goals. As data centers face increasing pressure to reduce their carbon footprint, adopting higher-temperature operations can be a powerful tool for minimizing energy waste and lowering greenhouse gas emissions.

Running a data center at 90°F and higher isn't about recklessly pushing equipment to its limits—it's about leveraging advancements in server technology and cooling infrastructure.  Modern server hardware is far more resilient than previous generations, designed to function optimally even at elevated temperatures above 104°F.  Manufacturers, owners, operators, and universities have conducted extensive testing and found that servers can operate at temperatures up to 95°F (35°C) without failure rate increases or performance degradation.

Overcoming the Heat Hurdles

Of course, allowing data centers to "run hot" is not without its challenges.  Operators need to ensure that their cooling infrastructure can handle the new temperature thresholds, particularly in areas where outdoor temperatures are high.  Failure to maintain efficient cooling systems can lead to hotspots, which could risk equipment overheating.

To address these risks, many data centers are adopting advanced cooling techniques, such as:

The Benefits of Running Hot

Raising the operating temperature of a data center isn't just about saving money—it's about optimizing performance and future-proofing the facility.  Data centers that operate at higher temperatures can adapt to new technologies faster, particularly as more companies transition to cloud and edge computing, which requires flexible, scalable infrastructure.

Higher temperatures can also improve reliability.  By reducing the strain on cooling systems, operators reduce the likelihood of equipment failure due to overcooling or moisture buildup.  As server hardware continues to evolve, built with more resilience to temperature variations, the case for running hot becomes even stronger.

Hot Data Centers: A Paradigm Shift

The shift toward higher data center temperatures reflects a broader change in how we think about energy efficiency and operational excellence.  Rather than focusing on keeping data centers as cold as possible to try to mitigate hot spots or other issues, the industry is recognizing the benefits of operating in warmer environments, allowing for reduced energy consumption without sacrificing performance.

For operators, the challenge lies in finding the right balance—allowing data centers to run hot enough to maximize efficiency but cool enough to ensure there are no issues or anomalies that cause alarms.  The rise of AI, cloud computing, and edge computing tools will further push the boundaries of temperature management in data centers, forcing the industry to continuously innovate.

Don't you wish your data center was hot like mine?  With a temperature management strategy, any data center could be more energy-efficient, sustainable, and ready for the future—because in this case, being "hot" is the cool thing to do.

Don’t You Wish Your Data Center Was Hot Like Mine?

Welcome to the future, where we crank up the heat in data centers because, apparently, cool air is so last millenia. You’ve heard of server farms, right? Well, say goodbye to farms and hello to server saunas. That’s right, we’re talking about data centers running hotter than your laptop after too many Chrome tabs—90°F and beyond, baby! Why cool down when you can heat up and feel the sizzle of savings? Let’s dive into this scorching new trend.

Why Be Cool When You Can Be Hot?

It’s 2024, and if you’re still keeping your data center at a chilly 70°F, you’re basically living in the Stone Age of server management. Everyone knows that the key to success is turning up the thermostat. Sure, your servers are working overtime, but who doesn’t love the idea of saving a whole 20% on energy costs by sweating it out?

Every degree closer to 90°F is like hitting the jackpot of energy efficiency. Who cares if it feels like a tropical vacation in your server room? Think of the savings! Forget fancy running your AC units at their max — let your servers sweat it out like they’re doing hot yoga.

Modern Equipment: Built for Heat and Glory

Remember when people used to worry about servers overheating? Well, that’s so 2001. Today’s hardware manufacturers are practically begging us to turn up the heat. They’ve tested their equipment in conditions so extreme it makes your average summer day feel like an arctic breeze. Google, Facebook, Meta —they’re all saying, “Bring on the heat!” These servers can handle 90°F like they were born in a desert... but they were actually forged in the fires of Hawaiian volcanoes.

We’ve got liquid cooling, direct-to-chip cooling, and hot aisle containment because nothing says cutting-edge technology like keeping your servers on the verge of spontaneous combustion - they were made to withstand worse. Plus, it’s a lot more exciting to visit! Who needs a freezer when you can live life on the server beach?

The Perks: Sweat Now, Save Later

Here’s the kicker—by running your data center at 90°F, you’ll shave up to 25% off your energy bill. Imagine telling your CFO that you’ve saved a fortune while your IT staff gets to experience their very own tropical oasis every day. It’s practically a corporate retreat. Who needs comfort when you’ve got cost savings?

Let’s not forget about the environmental benefits. Sure, we’re reducing carbon emissions by not cooling things down, but the real win is in letting your equipment do its thing under pressure. Hotter servers mean a greener planet, right? It’s practically heroic.

Hotter Data Centers: Living on the Edge

Of course, there are a few minor challenges. Like, you know, the rumor that higher temperatures might slightly shorten the lifespan of your precious equipment. But hey, what’s a little wear and tear when you’re saving all that money? Plus, with liquid cooling and direct-to-chip cooling, you can worry less about your servers frying and more about the potential for earthquakes or volcanos. It’s a thrilling balance!

Let’s also acknowledge the “comfort” factor for your employees. Working in a 90°F environment might not be ideal, but that’s what air-conditioned break rooms are for! Just think of it as team-building—nothing unites a crew like surviving a heatwave together.
