I've gone overnight, just didn't screenshot it. It's a Thermalright p120 extreme and yeah, it's a bit hot. It's much cooler at 3 or 3.1 with a reduced vcore, it's just 3.2 was my goal I've gamed for hours w/high graphics and it's been running now for weeks without error.
I think CoreTemp 0.95 uses the wrong Tjunction. Should be 85C for 4300s. That's the point where these chips will throttle. If you use version 0.94, then the reported temperature is 15C lower, or 64C (at the 65C design limit of the 4300). To discover the throttling temperature of your chip, crank up Vcore or run the CPU cooler without fan UP TO 5 min MAX. Make sure CPU throttling is ENABLED in BIOS and/or windows. Record the temperature at the first sign of throttling. Now subtract 20C and you will get the MAXIMUM SAFE FULL LOAD temperature.
I would guess that you should see throttling around 100C with CoreTemp 0.95.
