Are these temps and temp variability normal? Idle is no less than 35C, jumping to 45C almost instantaneously every few seconds, sometimes even 50-55C with minimal load. I'm using linux and the "on demand" cpu frequency scaler often underclocks automatically to ~2GHz when idling. The graph above is under such circumstances.
Under load, temps are constant at ~70C with fans pinned at 100%.
Just sitting in BIOS the temps are easily 45-60C. I want silent computing so I do have the fans at very low RPMs, but even when setting them to max speeds and sitting in BIOS the temps were basically the same.
I'm using a Noctua NH-D15 SE-AM4. I got that air cooler and the C7H specifically because I want silent computing while still allowing the 2700X to turbo up as much as it can automatically.
Your diagnostics are appreciated!

I haven't played with Asus Performance mode, the only thing I've done is set my ram to use the docp 3200 profile, set core performance boost (xfr2) to enabled and performance enhancer (precision boost 2) to level 2. With those settings I'm seeing all core clocks go up to 4.1-4.2GHz and single core go up to 4.35Ghz, after about 10 minutes of stress testing I'll see temps creep up towards 75 degrees and after that it'll bounce around 3.95-4.15 or so to keep temps right in that area.

I enabled Core Performance Boost , but didn't touch Performance Enhancer yet. Isn't that an unofficial optimization from an overclocker, and not PB2?

Did you check the timings set by DOCP? I compared to the XMP values and several are different. With DOCP settings my system failed mprime after 7 hours. It passed Memtest86 though. Tempted to retest with the XMP values. I also noticed a BIOS option for DRAM power (100% to 130% in 10% increments) with a description suggesting it be increased if doing current-intensive stress testing.

Is there a feature on this board to show CPU temp on the Q-code display? I think I read that somewhere but couldn't find it in the menus.

I'm confused. Are you manually setting vcore in the BIOS and also enabling CPB and setting Performance Enhancer to lvl 2? I ask because I am seeing vcore readings peaking @ 1.48-1.5 when setting PCB to Enabled and Performance Enhancer to lvl 2 and If I leave both those settings at Auto it peaks @ 1.41 under load. Even though I enjoyed seeing my CinBench R15 score increase by 25 points I am not sure that much vcore is good.
