HP Z820 2x Xeon E5-2680 3.1GHz - KeyShot 3.3.33 - 156.6fps

[DriesV]

• HP Z820 Workstation
• 2x Intel Xeon E5-2680 2.7GHz (Turbo Boost capped to 3.1GHz when all 16 cores are loaded)
• Intel X79 chipset (proprietary HP motherboard, 158B)
• 32GB RAM
• Windows 7 Professional 64bit

156.6fps on KeyShot 3.3 Pro 3.3.33

KeyShot is a blast on this system!

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. 

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.
