HP Proliant N40L Temperature

While doing some stress tests i monitored the temperature of my HP N40L. The N40L mainboard has 3 sensors: CPU, Nothbridge and Ambient. The room where the servers are located has a temperature of 20°C. Surprisingly the fan speed did not change, even at full load.

Here are my results:

Idle:
CPU: 34°C
North Bridge: 37°C
Ambient: 21°C

Moderate Load (Both CPUs at 50% and some harddrive activity):
CPU: 42°C
North Bridge: 38°C
Ambient: 22°C

Full Load:
CPU: 51°C
North Bridge: 39°C
Ambient: 23°C
