Liquid cooling is steadily gaining momentum in the enterprise space, particularly amid the intense computing demands tied to AI. CPUs and GPUs are operating at higher temperatures than ever before, and traditional air cooling is struggling to effectively keep those temperatures in check. Over the past few years, we have covered a range of liquid cooling systems, with JetCool emerging as a standout innovator in the field.
After connecting with JetCool at SuperComputing 2023, we brought their cutting-edge cooling technology into our Ohio lab, where we integrated it into an R760 server. To say we were impressed by its performance would be an understatement. To dive deeper into this technology and gain valuable insights, Brian invited JetCool’s founder and CEO, Bernie Malouin, to join him for a podcast.
Bernie describes himself as a technical professional with proven experience spanning from concept studies to full-scale deployment. For context, Bernie holds a Doctor of Philosophy (Ph.D.) in Mechanical Engineering, along with a Bachelor’s Degree in Mechanical and Aeronautical Engineering. Beyond his academic credentials, prior to founding JetCool, Bernie spent eight years at MIT Lincoln Labs, where he served as the technical and programmatic lead for a multi-sponsor research project focused on implementing advanced cooling technology in high-power RF devices for cutting-edge electronics applications.
While this podcast runs for less than 40 minutes, Brian and Bernie cover an extensive range of topics. We highly recommend watching or listening to it in its entirety, but if you’re short on time or need specific details on a particular subject, we’ve broken down the conversation into five-minute segments, allowing you to skip directly to the content that matters most to you.
00:00 Introduction
- The landscape
- It’s AI’s fault – or is it hype
- GPUs and CPUs need to cool it
- It’s about efficiency
- What’s the power budget?
- Wait! Liquid-Assisted?
06:00 Clarify Liquid Assist, please
- Getting technical
- Cold plates, closed-loop, and radiators, oh my

- Originally developed for aerospace applications
- What about the liquid?
- JETCOOL uses PG 25 (Propylene glycol)
- Benefits
- non-corrosive
- natural antifreeze
- non-toxic
- ready to use
- Benefits
- JETCOOL uses PG 25 (Propylene glycol)
- Top off the fluid
- can you go to a jiffy lube?
22:00 What happens when the hose breaks
- Leak tests
- Overpressure tests
- Only 8-10 Oz of fluid in the system
- Small puncture
- faulty seal
- might experience a few drops, but they evaporate
- the telltale sign that there is a problem
- CPU temperature rises
- Leak detection mechanisms
25:00 Looking for the signals
- OCP is dedicating two days for liquid cooling for their next conference
- Partners can do a better job of educating customers about liquid cooling
- Upgrade through the channel
- driving the pull-through
30:00 Yeah, but how much does it cost?
- An upgrade is about ten percent of the system price
- ROI
- within about six months
- Suitable for co-location services
- gaining efficiencies in co-lo facilities
- On-premises deployments
- limited space
- limited budget
- power constraints
- Heavy lifting performed by the Intern and Kevin
37:00 Silence is liquid gold
- One of the best benefits
- Simple to try
