Second thing to do is make sure your cooling fans are all facing the right
way.  My current case is a midi tower which hosts 5 disks, a CD-ROM and
two slot1 CPUs.I bought two extra cooling fans for the case, and voided my power supply
warranty to avoid it blowing hot air straight onto the CPU's.  I have the
front (original) case fan sucking air in, and the two extras at the rear
and the power supply sucking air out.  According to the BIOS (and
lm-sensors) I dropped the internal temperature 11 degrees doing this.  Of
course, in summer I can raise it 6 almost immediately by taking the case
The downside is with 7 cooling fans (I'm counting the two tiny cpu fans
and one in a drive caddy above those already mentioned) the ambient noise
level in the room is increased dramatically...
