Hi,

Were about to replace our Sun Fire 280R with a Sun Blade 2000 the reason
for the change is that the Sun Fire 280R is too noisy for our small
office, however I've been told by our supplier that the Sun Blade 2000
isn't much quieter than the Sun Fire 280R, I was hoping the Sun Blade
2000 would be about the same noise wise as say a Sun Blade 100, can
anyone shed any light on this, I've read the specs on Sun's website and
the decibels for the SB100 & the SB2000 look close but without having
the machine in front of me it's impossible to tell

Regards

Paul Hirst

Hi, we don't have Sun Blades 2000 here, but sunsolve list its noise level
at 56.4dB operating and 47.7dB idling (I guess it would also depend on the
disks etc), whereas SB100 is specified as 45dB and 50dB and 280R is
specified at much higher level of 69dB.

I guess everything else is subjective.

HTH, Dragan

I've got an SB1000 and it is exceptionally quiet.

The Blade 2000 starts up sounding like a jet about to take off, but
once it begins to load the OS everything quiets down quite a bit.

We have users with Blade 2000s (900Mhz models)sitting close to them
beside their desks and the noise level has never been an issue.

The Sun Fire 280R is made for cabinets,
The SB2000 is made for offices.
My SB1500 has a temperature-controlled fan and is even less noisy than
a SB100. So I think the Sun specifications apply when the workstation
is fully equipped.

OT: i change the front fan of my home Ultra-10/440 today.
The new fan is papst 92mm. 25decibel fan. 19XX rpm.
the Ultra-10 is according to specs 52 decibels.
now very quiet, i guess 35-40 db.

temp on U10 was: in 23 out 33
new fan: in 23,5 out 33 celsius.

internal disk not in use, external scsi.

ofcourse when changing the front fan i removed the dust
that has grown inside the cover.

Be careful with that. Papst are for shure one of the best fans you can
get, but the onboard connector for the CPU fan has only around 9V not 12V
as seen on most fan datasheets. I burned my U5 by replacing the "Sun" fan
by one with exact the same throughput at 12V. It was a very hot summer
those days.

Today I have connected the same Papst fan at 12V and the machine is still
fine for 2 years now and as same as quiet as with the same Papst fan
driven at 9V but of course with a much higher airflow. So Papst rules :-)
...sun should consider to choose Papst fans, as Fujisu/Siemens does in some
Systems, instead of their cheapy ones :-/.

thanks, i was totally unaware that the fan pins don't deliver 12 volts.

Don't forget the Ultra 5 was perhaps the cheapest, nastiest Sun
computer ever. I'm sure fan quality was not often on their minds,
considering the crappy disks, crappy IDE implementation, crippled
case, horrible on-board graphics etc.

The best way to fix an Ultra 5 is to throw it out of the window and
start with an Ultra 10 instead - making sure to get a 2MB cache cpu if
at all possible. Then it is possible to fit acceptable disks, cd-rom,
graphics etc (U5 cannot do UPA graphics, which are the nicest thing to
fit, IMHO). At that point the machine is perhaps worth after-market
fan upgrades.

Of course, this is just my biased opinion, and I'm sure an ultra 5 is
better than no sparc machine at all (everyone should have at least one

You do realise the U10 is a U5 board in a mini tower case, don't you?

Point well made about the UPA slot being inaccessible in the U5 though.
