Xserve: fans speeds?

What fan speeds have you got? I've got an incredibly noisy one, all fans bar PCI are on 12,000rpm.

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

Nothing showing up in top that's eating cycles... So what are the various temperatures and voltage or current readings? What kind of environment is it in?

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

What kind of environment is it in?

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.

Yes, dual G5 @redacted.invalid 2.3 GHz, 3 drives, 6 Gb RAM, Tiger Server.

I think I'd try takign the fax machine off the top if I were you - it's not really designed to support weight. Also I bought four chunky stick on feet for mine - helps the air flow underneath and also reduces the noise transmitted through the surface that it sits on, which otherwise tends to act like a sounding board.

OK, I'm seeing CPU Ambient temps of 24/23, and Internal of 50/45. Memory is 52, PCI 50, Controller is 49 so yours is running hot; I'm only measuring one of my Xserves, but it's one I'm stressing by NetRestoring from it over NFS to an entire lab. My other is much cooler.

For comparison, the fan speeds on that hotter machine are all ~5400rpm, except SysController (7200) and PCI slot (5700). Yours is, indeed, going mad.

"On top of a trolley" and "big fax machine sitting on it" suggests it's not in a rack, there's definitely no airflow over or under the machine and nothing driving air around it at all...apart from the fans driving air through. Perhaps you missed the bit on p21 of TFM where it says "To ensure safe and smooth operation of your server, it's essential that you plan for proper location of the server in its rack, adequate power to the components in the rack, and the appropriate operating environment for the rack"?

There is no location to put a rack in. The only possible place for it is where it is. Whilst I'd love to sell them a rack for the Xserve, a 1U rack just ain't possible. So we're saying that it requires sufficient airflow over he surface of the case, not just through the intakes?

Paul, it your's racked?

What's the point of buying an Xserve if you aren't going to put it in a rack??

Mine's not racked but, as I mentioned earlier, I put some stick-on feet on the bottom to raise it off the shelf that it sits on, which helps with air flow and also helps to reduce the "sounding board" effect. There is also nothing else on top of it, so it gets reasonable air flow, both top and bottom.

I'll see if I can persuade them to move the fax machine and stick some risers under it.

Bonge gets higher commission on them?
