Xeon-D or Xeon E3-1240L for quiet build

[Jan Egil]

I am in the process of upgrading my home-server. Currently running debian with zfs (6 disks in raidz2), using it for file-sharing, plex++, and various small services.

I am comparing the Xeon D-1520 (X10SDV-4C-TLN2F) and the xeon e3-1240Lv3 (Asrock E3C224D4I-14s)
My main focus will be to build a quiet computer, and I think both of these will have enough power for my needs. Currently I am using the xeon E5310, which is more than enough, and the 32GB memory limit won't be a problem. I have also been looking at the 2750, which I am afraid will not be powerful enough.

Looking at the TDP, the E3 is an easy winner with 25W TDP compared to 45W TDP of the Xeon D. I am however a bit confused as to whether or not these can be directly compared, give that the Xeon is a SoC. I guess there might also be differences when it comes to idling power.

My question is basically what the best choice would be with regards to heat and thus noise? I am also open for other options.

e3-1240Lv3 has my vote / technically lower power / lower heat and likely more fan/hs combos to make it quieter than the xeonD options right now

I'm running a dual L5320's currently and am waiting on the skylake E3 benchmarks. Either looking at the same D-1520 board or a skylake E3-1200 vintage setup.

I'd stay clear of the 2750, the single-threaded performance with some Plex configurations is a major hamstring.

Personally I'd say choice of enclosure is far more important for noise considerations rather than choice of CPU... but it'll certainly be easier to find potentially quieter aftermarket coolers for E3's than for Xeon-D's.

xeon-d 1540 is spendy, but you get 16 threads vs the 8 of the v5 1240L, do you need those extra threads?

Personally I think the 1240L v5 might be the route I will go as the Xeon-D is just out of my reach.
