CPU Heatsink
============

The bigger, 3U, heatsink for  my Raptor Blackbird system arrived today.
It's not only bigger but it also  incorporates the fan. That fan is not
on a  top of the  system but on  a side (on  that side which  faces the
PCI-E slots - so in my case it is the bottom side).

In order to connect that fan I have had to turn off one of case fans.

It  actually makes  some  difference.  On startup  the  system is  much
noisier that it was  with three fans (now there are  just two case fans
and that CPU fan). After that the system is almost quiet.

But temperatures are now under 50 degrees of Celsius. Previously I used
the "powersave" CPU governor and now I use the "ondemand". Temperatures
were previously  about 60-62 degrees and  now are about 50  degrees for
most time.

But the main  difference is noise. Now the system  is almost quiet even
under load. In the previous configuration it was much noisier.
