That's a monster! About 10x the speed of my crappy laptop.
Now overclock it and see if you can crack 200
You can't overclock the newest generation (E5) Xeons. ;D
Also, this thing is 16 (!) times faster than my old system!
Quite honestly, it is ridiculously fast. Almost 2 times faster than my overclocked 3930K (4.4GHz, 83fps) based system at home as well.

At full load and after several hours of rendering the hottest core is hitting 75 deg C (according to HWMonitor). All cores stay nicely between 70 and 75 degrees.
This is with fan speed setting in BIOS at level 3, which brings acceptable noise. Level 7 is the maximum speed, but then the Z820 sounds like a JET!!
Is 75 deg C acceptable for these CPUs, in the long run?

Wow, that is very hot. Of course 130W is a lot of heat to dump through a processor continuously.
What coolers are you running? LGA 2011 coolers aren't common, and many are server case (rack mount) stlye low-profile coolers (consequenlty, they sound like a JET - we have an older dual xeon LGA 2011 machine in the office with the exact same issue). If your case can handle it, 2 of these might solve your problem: http://www.newegg.com/Product/Product.aspx?Item=N82E16835608024 They will run much cooler and make a lot less noise.
For any Z820 users out there:
It might be worthwile to increase idle fan speed in BIOS from factory default ...... to ***....
This introduces some humming noise from the fans, but CPU temperatures never go above 64 deg C on a dual E5-2680 system.
With fan speed setting **.... I got 75 deg C max.
