Even without being assembled inside a case, the tested board delivered excellent temperature readings, as shown in the table below:

Sensor Name	Value	Description
VPU	+34.0 °C	Video Processing Unit temperature
GPU_btm	+34.0 °C	GPU bottom sensor (lower part of chip)
GPU_top	+36.0 °C	GPU top sensor (upper part of chip)
SOC_BRC	+37.0 °C	System‑on‑Chip bridge controller region
DDR_btm	+37.0 °C	DDR memory bottom sensor
DDR_top	+38.0 °C	DDR memory top sensor
CI	+35.0 °C	Camera Interface / multimedia block
NPU	+35.0 °C	Neural Processing Unit temperature
CPU_M1	+35.0 °C	CPU cluster M1 (middle core)

Running benchmarks and checking temperatures.

In short, the script is a benchmark runner with temperature monitoring:

After each test, it stops the logger and calculates the minimum, maximum, and average temperature recorded during that run.

It runs five performance tests (CPU, memory, storage, GPU, and stress) one after another.

Each test lasts about 2 minutes, so the whole suite finishes in ~10 minutes.

While each test runs, it starts a background loop that calls sensors every 5 seconds to log system temperatures.

#!/bin/bash
# run_benchmarks_with_temps.sh
# Benchmark suite with temperature logging via sensors
# Total runtime ~10 minutes (5 tests × 2 minutes each)

REPORT=./benchmark_report.txt
echo "=== Benchmark Report with Temperatures ===" > $REPORT

# Helper function: run a test + log temps
run_test() {
  NAME=$1
  CMD=$2
  LOG=./${NAME}_temps.log

  echo "Running $NAME..." | tee -a $REPORT

  # Background temperature logger
  (
    while true; do
      echo "=== $(date) ===" >> $LOG
      sensors >> $LOG
      sleep 5
    done
  ) &
  MON_PID=$!

  # Run the benchmark
  eval $CMD | tee ${NAME}_output.txt

  # Stop logger
  kill $MON_PID

  # Extract temps: only lines with "temp" or "CPU", ignore 0.0°C
  TEMPS=$(grep -Ei 'temp|cpu' $LOG | grep -Eo '[+0-9]+\.[0-9]+°C|[0-9]+°C' | sed 's/[+°C]//g' | awk '$1>0')

  MIN=$(echo "$TEMPS" | awk 'NR==1{min=$1} {if($1<min)min=$1} END{print min}')

Test report

Based on our results shown below, the board didn’t cool much, which indicates that the active heatsink is performing well as expected.

Test	Min Temp (°C)	Max Temp (°C)	Avg Temp (°C)
CPU_sysbench	36.0	55.0	50.20
Memory_sysbench	47.0	55.0	51.67
Storage_fio	39.0	47.0	40.66
GPU_glmark2	42.0	49.0	45.75
StressNG	40.0	67.0	59.38
