Hello everyone! 
Today, a quick focus on a historic technology that has been running silently in our datacenters since 2003: our liquid‑cooling system.
If you run intensive workloads with us, here’s what it changes for you:
Direct Liquid Cooling (DLC): No more over‑air‑conditioned server rooms. We bring water directly to the components that heat up (CPU/GPU) via waterblocks manufactured in our factories. Heat is captured at the source.
Check out how it works in a video on our YouTube channel: https://www.youtube.com/watch?v=wtt_UX2UmH0
A controlled PUE (Power Usage Effectiveness): Thanks to this closed loop coupled with natural airflow, we achieve an average PUE of 1.28 (versus ~1.5 in the market). In concrete terms: less energy wasted on cooling, and a reduced carbon footprint for your projects.

Maximum performance (Zero Throttling): A poorly cooled CPU throttles its frequency to protect itself. Our water‑cooling maintains a constant optimal temperature. Your Bare Metal servers can thus exploit their Turbo Boost longer, without risk of overheating.

Over to you!
Cooling is often a headache. Have you ever had to throttle your machines because of heat? Did you know this technology equips our racks?
