I have the same motherboard as well and my CPUs get up to 60C with an unmodified sdr file and two 4U Supermicro heatsinks. My case has (3) 120mm PWM fans and (2) 80mm fans in the rear, so I can only speak for my setup and it's temps.

Sure, my CPU heatsink fans increase in speed when I'm running an encode or transcode job (this box has Plex running in a Docker container).
Oh man, more difficult buying choices for those of us with LGA 2011 boards... I was leaning heavily toward going with the $350 E5-2695 v2 QS chips on eBay but the single core clock speed on these is pretty enticing.
But then again, does the Ivy Bridge designation of the v2 chip compensate for the slightly lower clock speed in single core performance? Basically we're comparing a 12-core, 2.4 GHz Ivy Bridge vs an 8-core 2.7 GHz Sandy Bridge?

To add to the difficulties, like many others here also report Turbo Boost automatically keeps my E5-2670 at 3 GHz even under full load on all cores, so I never see 2.7 GHz. Not sure about how the E5-2695 does, but for my use case I would surely take 12 cores over 8 if they drop in price further.
I'm pretty sure the turbo requires good cooling though so your results may vary. (I'm on dual Hyper212EVO but not super good case flow.)

If those 2695's do vt-d and run dual cpu properly I may have to start planning to trade up.
2.9Ghz is a better base clock than my 2670's.
... Although truthfully I'm perfectly happy with my 2670's and I should probably be thinking about all the other things that should be higher on my list.

I'm liking those E5-2695 V2 already! If they drop for 150$ a piece i may end buying them,
But as far as single threaded performance goes they are a little bit weaker than the E5-2670 but a couple of them should net around 3K points in CB15.

Looks like the prices of E5-2670 chips are actually going high. I recently paid $150 for a pair to replace E5-2630 processors in my PowerEdge R620.
These chips run hot though. Temperatures are in the range of 65C~80C on heavy load depending on the ambient temperature. These processors are passively cooled on R620 and there is no way to lower the temperature without making the server sound like a vacuum cleaner.
Looking forward to replace these E5-2670 chips with v2 Xeons when they become more affordable.

The 2680's in the $70 - $75 range are mostly SR0GY. If you need the latest SR0KH stepping with VT-d, you will have to spend about $100 for each processor. So at this point of time, the 2680 is costlier when compared to 2670 if you want the latest stepping. The price difference may come down, but I don't think 2680 will be sold for anything cheaper than the price of 2670.
...as the BMC controls the speed of the fans, you typically can't adjust them through the OS. If you need to speed them up, you can either adjust the PWM offset in the bios, or more drastically, hack the SDR (sensor data record) file (then run through the FRU/SDR update procedure).
Ah.. I already did that. That's quite sad actually. You can't even adjust them via IPMI.
On another note, this workstation build has taught me a lot. Hopefully i can write a lengthy post to anyone who is new to workstation builds.
Tried to put in my old GTX 770 and it wouldn't fit because there wasn't enough clearance so i got a GTX 1060 Mini and fits perfectly.
It uses closed loop temperature control in the matching Intel chassis. It has thermal targets and leaves fan speed alone until those thermal targets are close to being exceeded. Then it will ramp the fans to hold the system temperature at the thermal targets.
In the 1u case, changing the sdr file only resulted in a reduction of fan speeds from 14,000 to 9,000. I tried a fan controller but the fans burnt out the controller. Finally, I used separate 4-pin resistor cables and the fan speeds are now 3 - 4,700 rpm. The two cpu temps went up from high 30-40's to 40-50's. The noise reduction was substantial. I can now sit next to the server.
on an Intel board you have to update the UEFI with a compatible chassis model, afterwards they would spin down.
