The temperatures you've posted look fine to me. A simple search over on the XServe forum offers some threads discussing differing temperatures you could use as a rough yardstick?
"I keep reading a lot on "Server Monitor", however I am on OS X Lion and dont seem to be able to find it anymore?"
Are you sure? Lion's Server Admin tools are available for download here:
If you're using Server Admin you must have done this already? If it was deleted accidently simply download and re-install again. The installer creates a folder in /Applications named Server. If it already exists it simply overwrites it and installs afresh. After the re-install you should find Server Monitor in there.
You may not be aware but you can install the Server Admin tools on a non-server OS-compatible client. You can run the server administration applications (including Server Monitor) remotely.
If the hardware is in a large-ish room with good air circulation I would not worry too much about no air conditioning. If it's in a small-ish cupboard with very little air flow I would re-think where you're siting it. Ideally and if you can afford it use A/C.
Thank you so much for your reply. I did look at those threads but I just wanted to be extra safe thats why I started this thread. (:
Anyway, I believe I've purchased the "Server" app from apple store, thinking thats the server administration tool but I was wrong.
Thank you so much for the link you provided, I finally have Server Monitor app (:
tempertures look fine to me
it would depend on load, if server was in aircon room etc
to give you an idea, xserve cpu 10-20%
in airconditioned room, room temp 20 deg C
system board 40-45 deg
memory modual 55-60 deg
power supply 53 deg
blowers 5500 - 6700 rpm
you can montor the hardware with server monitor
you'd need to configure LOM for this
