We have a few dozen T630/T620 servers and recently started purchasing
the T640 models. I noticed that the T640 models exhaust noticeably more
air through the rear than a similarly equipped T630/T620 sitting in the
same rack (causing an increase in noise). I consider the T640 a quiet
server, but they are not as quiet as the preceding generation and they
are certainly not silent (nor would I expect them to be).
I don't have any other Dell 14G servers around for comparison, but I
would assume that these fan changes were made intentionally and across
the board for the 14G server line so that the T430 -> T440 fan speed
increase would be similar to the T630 -> T640 increase. I believe you
can still purchase the 13G servers (minus some options that used to be
available), if noise/volume is a priority in your application.

Hello everyone:
I have a T640 here and can't get it anywhere near to silent. It's
equipped with two "Intel(R) Xeon(R) Silver 4114 CPU @ 2.20GHz" CPUs, a
BOSS System for the OS and nine 4TB NL-SAS disks. System profile is
set to "OS DBPM" and /proc/cpuinfo shows 800MHz for all cores, when
nothing CPU intensive is running. However, fans are always running
with at least 50%.
OK, this machine will end up in a server room, and I already learned
from the DELL hotline that this should be normal since the chip-set
temperature causes the fans to run as fast as they do.
So my real question is: has anyone out there experience with the noise
level of a T440?
I plan to order the T440 with the same two CPUs as above, plus BOSS
card, only two 2.5" 2TB disks, additionally a QuadPort 1Gb network
adapter. Maybe a GPU card (low to mid performance).
The DELL shop advertises it as "Powerful, expandable and quiet", and
I'd like to verify the "quiet".
Other hints are also welcome.
Thanks in advance,
Peter
