X41T CPU Temperture

[Yotam]

I installed "Centrino Hardware Control" and it reports CPU temp about 56-58 degrees (celsius) when running on full CPU performance, AC power but low CPU load. When CPU load gets higher temperture can reach 65 degrees and more, and I didn't install an additional RAM module yet.

1. Is this normal?

2. Can I lower these temps? How can I control the fan? (I don't mind it to run a bit faster, even if it will make some noise)
I set the fan to "maximize performance" in power manager.

3. What other may influence the temperture? Nothing blocks the fan.

Thanks!
