Just wanted to report (and update) on my 3700X Idling temperature issues. I figured out that the base default vCore value for the CPU in my BIOS was just too high. Really that simple. It was sitting at 1.43v, unnecessarily. So I just reduced it by increments. I can't type in an actual vCore value, but I can manually adjust via Offset (minus, or plus; obviously went with minus), and then used the default minimum increment as shown at the bottom of the page in the BIOS description of 0.00625v (that's the minimum value). I multiplied it a couple of times (did about 4 restarts) until I got to 0.00625v x 15, for a total of 0.09375v. Now, the base vCore sits at around 1.37v (give or take a bit) and my Idling temps went from anywhere in the high 40's to around 49 or 50ºC at times, down to 39ºC to 40ºC (varies just a bit but stays there more consistently and doesn't just jump around as it used to). The voltage for the CPU in the BIOS was plain and simple way too high. As of this typing my system is still stable and the boost function still works, reducing the vCore to something more reasonable (but not too much either) simply helped the case and didn't hinder the performance.
