Measure Raspberry Pi temperature

Make a temperature note:

vcgencmd measure_temp

To create a stress test at first sysbench tools must be installed:

sudo apt-get install sysbench -y

Now the test-heatsink.sh script:

#!/bin/bash

clear

for f in {1..10}
do
vcgencmd measure_temp
sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run >/dev/null 2>&1
done

vcgencmd measure_temp

To install it globally enter super user mode:

sudo su

Paste this content:

cat > /usr/bin/heatsink-test <<EOF
#!/bin/bash

clear

for f in {1..10}
do
vcgencmd measure_temp
sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run >/dev/null 2>&1
done

vcgencmd measure_temp
EOF
chmod 755 /usr/bin/heatsink-test
