CPUs and GPUs are running hotter, and traditional air cooling struggles to keep those temperatures down. We have covered several liquid cooling systems over the past few years, with JetCool being a standout player. ![]() After running into JetCool during SuperComputing 2023, we brought their technology into our Ohio lab, nestled inside an R760. To say we were impressed would be an understatement. To gain more insight into this technology, Brian invited JetCool founder and CEO Bernie Malouin for this podcast. Bernie describes himself as a technical professional with demonstrated experience from concept studies through deployment. By the way, Bernie also holds a Doctor of Philosophy (Ph.D.) in Mechanical Engineering and a Bachelor’s Degree in Mechanical and Aeronautical Engineering. That’s impressive, but before he founded JetCool, Bernie spent eight years at MIT Lincoln Labs. He was the technical and programmatic lead for a multi-sponsor research project to implement advanced cooling technology in high-power RF devices for advanced electronics applications. Although this podcast is less than 40 minutes long, Brian and Bernie cover a lot of ground. It’s worth viewing or listening in its entirety, but if you are short on time or need specifics on a particular topic, we have broken down the conversation into five-minute chunks so you can skip around.  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 - Efficiencies in cooling with JETCOOL - Arrays of tiny fluid jets - Surgically removing heat - Now, where are those heat nodes? - Profiling the CPU 10:00  Relationships with the chip makers - Staying ahead of the curve - Chip makers – partners in design - Details on where to cool - Tiny pumps - micro DC brushless pumps - circulating fluid throughout the server 15:00  Let’s talk about pumps, cold plates and radiators - Radiator technology - Modified technology in Formula One racing - Proven reliability - Cold plates - 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 - 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 Wrap-up: Stop by JETCOOL at OCP in October!

My background, though, is writing. So I decided to get out of the pre-sales biz and return to my roots, doing a bit of writing but still being involved in technology.
