Normally, I set the fan on the third or the fourth green LED
for 'good' temperature and 'enough' air flow.

Red Volvo 2001 XC70
- At the third or fourth green LED, the noise at the heat core is as louder
than the brown Volvo at full blast.
- At full blast, the air flow is as low as the brown Volvo at second LED.

So it looks like the red Volvo is working much harder to produce.
