Anyone got an Xserve they can login to?

What fan speeds have you got? I've got an incredibly noisy one, all fans
bar PCI are on 12,000rpm. I can't get the bloody thing to shut up.

Nothing showing up in top that's eating cycles...

Hang on...

CPU1 Inlet 37C
CPU1 Ambient 45C
CPU1 Internal 48C
CPU2 Inlet 31C
CPU2 Ambient 39C
CPU2 Internal 55C

System Controller and memory seems hottest at 57C

Sitting on the top of a trolley with nothing obstructing front or back
vents. It does have a big fax machine sitting on it. Do they dissipate
much through the top case?

The load on it should be pretty minimal. Small file serving, DNS, DHCP
and Mail.

What sort of fan speeds are typical?

On my G5 Xserve here, most of the fans are at around 4k rpm, except the
system controller fan, which is at around 5.5k. Highest temp is system
controller internal, at 49 C.

IS yours a dual? This ones a Dual 2.3Ghz with 2Gb RAM, and 3 internal
drives. Stacked basically. More watts to dissipate?

are you booting it in target disk mode? if so, the fans will always run
at 100% speed. also check the PSU and the PSU cable, make sure they
are fitted in tightly.
average fan speed for mine is around 4K RPM to 6K RPM, up to 12K when
under heavy load, cluster node makes more noise for some reason even
with same system temp as the others.
