Hi Peter,
I have a PET440 here and use it as a workstation/server. Specs are similar
to yours:
- 2 * 4110 Xeon Silver
- 3*32 gb 2133 LRDIMMS
- H730P
- Various SSD Evo's + 1*8Tb disk.
- MSI 1030 GPU
- quad-gigabit NIC.
The server is whisper quiet but it took some love to get there.
- There is no more a one-size-fits all 3rd party PCI fan response.
Instead, this is now done per slot. Look for this in the idrac GUI under
'Hardware Settings'. I suspect you can do the same with your T640.
- The server is -very- picky about components health (there are a lot more
sensors). At one point it was pushing 100% fan because of the lack of a
temperature sensor on the 850 evo SSD which was behind the H730P.
Upgraded to 860 evo's, problem solved.
- the x16 slot for GPU only gets enabled when you have two Xeons, not one.
- if you want a GPU that draws more power than that provided by the PCI
slot, please remember to order your server with the GPU kit as it cannot
be retrofitted/ordered afterwards. I am planning to research this soon.
- server idles around 1280/1300 rpm but I liked it lower so my fan runs at
1080 rpm with a watchdog to check for temp spikes. The cpu temp rarely
reaches 40C.
- with one cpu, my T440 idled around 66Watts, with two it's around
88Watts.
I hope this helps.
Regards,
Vincent

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
