====== Host hardware and cooling ======

==== Compute snapshot ====

At roughly **2026-10-25 16:20 UTC**, ''lscpu'' identified one Intel Core i9-10900X CPU at 3.70 GHz, with 10 cores and 20 logical CPUs. The host reported 125 GiB RAM. The root NVMe filesystem was 915 GB total with about 275 GB available. These are observed capacity readings, not a parts list or guarantee of free capacity at a later date.

''nvidia-smi'' reported two NVIDIA GeForce RTX 3090 cards, each with 24,576 MiB of reported memory. Both were fully utilized during the sample. GPU 0 reported 59 °C, 272 W, and 99% fan; GPU 1 reported 70 °C, 273 W, and 100% fan. The GPU workers and their process IDs are transient, especially during the pending ''f7a4de4'' rollout. Recheck live values before attributing a temperature or load to a particular workload.

==== Sensors and cooling evidence ====

The same host’s ''sensors'' output showed CPU package temperature near 70 °C. The board monitor reported SYSTIN 40 °C and CPUTIN 44 °C; several fan channels read zero, while ''fan2'' read about 1436 RPM. The channel labels are not mapped to physical fans in the evidence, so zero readings must not be interpreted as failed fans. ''AUXTIN4'' reported 85 °C against an 80 °C high threshold, but its physical sensor mapping is also unknown. Preserve that as an unmapped sensor reading and verify its meaning before drawing a cooling conclusion.

The system unit ''inference-fans-fullspeed.service'' was inactive when checked, despite the GPU fans reporting near-maximum speeds under load. No verified chassis, CPU-cooler, or fan-layout record was found in this snapshot. Do not infer the cooling design from unit names or board sensor labels.

==== Recheck ====

Run ''lscpu'', ''free -h'', ''df -h /'', ''nvidia-smi --query-gpu=index,name,memory.total,temperature.gpu,power.draw,utilization.gpu,fan.speed --format=csv'', ''sensors'', and ''systemctl show inference-fans-fullspeed.service -p ActiveState -p SubState''. The fan override unit is ''/etc/systemd/system/inference-fans-fullspeed.service''; hardware values are live command output rather than a saved diagnostic file. Last sample: approximately 16:20 UTC, 2026-10-25.
