SUMMARY: V880 fan speeds

First off, a big thank you to all the people who responded.

The IO fan speeds in our V880 are right in line with everybody else. Even
though the CPU temps are similar, we're running 200-500 RPM faster than
average (although it should be noted that one person actually had faster CPU
fans speeds than us).

I have Sun out looking at the box and they think it's a bit loud as well.
The room is cool enough that the fans should be kicking down to the
2200-2400 RPM range and they're not. 

Even at 2200 RPM, this machine is a lot louder than our E450. I'm not
exactly sure what the Site Planning Guide is measuring, but in our
environment a V880 is about 2-3 times louder...

Thanks again to all who resonded!

Hi all -- We just got in a V880 and it's a lot louder than we think it
should be. Thought I'd ask what other people with similar machines were
seeing as far as fan speeds go. 

This machine has 4x750MHz CPUs and is fully populated with 12 drives. We
only have 3 cards: PGX64, QFE, and another FC-AL host adapter. The ambient
room temp is about 72 deg F. Here's what kind of fan speeds we're seeing
after the OS is booted (taken via /usr/platform/sun4u/sbin/prtdiag -v):

IO1_PRIM_FAN             4000        [ENABLED]      OK
IO0_SEC_FAN                 0        [DISABLED]     OK
IO1_SEC_FAN                 0        [DISABLED]     OK
IO_BRIDGE_PRIM_FAN       3614        [ENABLED]      OK
IO_BRIDGE_SEC_FAN           0        [DISABLED]     OK

According to the "Site Planning Guide for Entry Level Servers" that Sun puts
out, the V880 is supposed to run at 4.7 bels and an E450 at 4.9 bels. The
V880 is a *lot* noisier than our E450, which seems odd given the noise specs
from Sun's book.

Just wondering if anybody can send me the prtdiag output for the fan banks
on their V880. Thanks a bunch!

P.S. - Here's the temp output for comparison:
