Air-cooled
Outside air below 10 °C for 300 days a year. No chillers to power.
Pick a size, pick a term, and run on GPUs cooled by Arctic air and powered by hydro. Most clusters are live within eleven days.
Six things you get with every Nordlys cluster, whether you rent eight GPUs or a whole hall.
Outside air below 10 °C for 300 days a year. No chillers to power.
Every kilowatt-hour from hydro and wind on the NO4 grid, matched hourly.
Free-air cooling means no evaporative towers, in summer or winter.
Waste heat leaves at 35 °C and warms Narvik’s district network.
Every pod gets its own 3.2 Tb/s InfiniBand fabric. No noisy neighbours.
PUE, load and carbon metered every hour and exposed through the API.



Outside air below 10 °C for 300 days a year. Fans move it through the halls; there are no chillers to power.
Free-air cooling means no evaporative towers. The halls use no water for cooling, in summer or winter.
Waste heat leaves the halls at 35 °C and flows into Narvik’s district heating network.
Two of the labs training in Hall A, in their own words.
“Our training runs used to stall on thermal limits every summer. In Narvik they just keep going. Fewer restarts, steadier throughput, and a power bill we can plan around.”
01 / 02Live telemetry“We moved 512 GPUs north in eleven days. Same fabric, same tooling, and every kilowatt-hour now shows up as hydro on our carbon report.”
02 / 02Hydro-poweredUp to 512 GPUs are ready in about three days. Dedicated pods up to 4,096 GPUs are racked and burned in within eleven days. Larger builds are scheduled with you.
In Norway, inside the EEA. Data never leaves the hall unless you move it, and sovereign tenants hold their own encryption keys.
NVIDIA H200 today, with B300 pods bookable from Q1 2027. Every pod sits on a dedicated 3.2 Tb/s InfiniBand fabric.
Per GPU-hour, all-in: power, cooling, fabric and checkpoint storage are included. Longer terms lower the hourly rate.
Yes. Run Slurm, Kubernetes or bare metal, with your own images. Our engineers help with the first deployment.
