But the u45 is making about the same noise than the Blade 2000 and a
2500 I would say!

The 2500 has to high speed on both CPU fan and disks which causes fan to
increase speed due to the air will not go out fast enough of the
disk/cpu, if reducing the speed the temp will not go up and the noise is
much less.
