The problem with my Sun V20Z servers is that a single one of the V20Z 's
makes more fan noise than 10 IBM x345's due to the fans that are always
on at 3600rpm and do not regulate speed with chip temperature.
Sun advertised the V20Z as being able to adjust speed with die temp, so
I am not sure why mine doesnt.
They stay at 3600rpm period.
QUESTION: HOW DO I SET THE V20Z FANS TO USE THE CHIP TEMPERATURE TO
ADJUST SPEED?
Additional info after logging into the service module (where presumably
the fanspeed can be set).

Trying to set fanspeed tells me I need a new bios.
I tried to flash the newest bios but i received a Java Error as the
documentation and the software differs substantially.
Either way, I would appreciate it if someone can give me guidance how to
get the fans to regulate as the fan-noise is driving everyone nuts in a
business setting.
There must be some config possible, as my IBM x345s are very very quiet,
and i see no reason why the Sun V20Z's should be so loud.
If you feel the question is inappropriate for your newsgroup please
advise me where else I can go. I need a solution fast .
Thanks
