Question I7-3820 crashing/overheating with handbrake video rendering

[Gaberman]

I get all manner of BSOD crashes when rendering video with Handbrake or sometimes even just editing video in PowerDirector. Here is my current build:

Intel Core i7-3820 3.6GHz 130W Quad-Core CPU
Noctua NH-U9B CPU Heatsink
ASUS P9X79 2011 Motherboard
NVIDIA GeForce GTX 750
32GB (8 x 4GB) Mushkin PC3 12800

Here is idling (using RealTemp 3.7):
Temperature (C)
46/43/45/50
Distance to TJ Max
54/57/55/50

Here are values from CPUID HWMonitor about 30 seconds before a recent crash:
Tjmax 100.0 °C
Core Speed 4675.2 MHz
Temperature 0 83 degC (181 degF) (Package)
Temperature 1 79 degC (174 degF) (Core #0)
Temperature 2 82 degC (179 degF) (Core #1)
Temperature 3 80 degC (176 degF) (Core #2)
Temperature 4 83 degC (181 degF) (Core #3)

I've tried messing a little with the Handbrake settings for rendering, but no luck yet, and wanted the opinion of this community before messing more.
Thanks

Is your system running at stock? If not, try clearing the CMOS and run it at stock to see if it still crashes.

Thank you. I went into bios settings and set them to "optimized". Cores now run around 64C max when encoding. No crashes since. Will update if further crashes occur.
