New AMD FX-8320E Vishera 8-Core 3.2GHz (4.0GHz Turbo) Socket AM3 idles at 50 degrees!!!

I personally prefer HWMonitor. What is your ambient temperature?

Are you using the stock cpu cooler?

50C at idle sounds too hot especially for a 8320E that is suppose to be low leakage and have lower stock vcore to begin with. Gives us the Thermal margins from AMD Over Drive and then give us the Package Temps and CPU Temps from HWMonitor.

Awesome. First thing first, 1.4335V shown in your first picture is way too high for your current settings. Picture shows x16 multiplier for CPU and a 200 FSB. That's a 3.2GHz FX 8320E and voltage should be more like 1.1XXV. With a voltage like 1.4335 you can probably OC hotter FX 83XX CPUs to 4.7GHz. You probably want to manually set the voltage to a more ideal voltage. An ideal voltage would be 1.1625V as that's what CoreTemp shows for your VID. It would kind of make sense that the CPU/motherboard would use 1.4335V when the CPU boosts to the Turbo Boost speed but it is way too much in my opinion. Even with the older Visheras the 83XX CPUs could run ~500MHz above the stock speed with the stock voltage. Your chip is a better binned, lower leaking 8-Core so it shouldn't need voltages that high for normal usage.

Second picture nothing seems wrong. One thing I will tell you what temperature readings are important in HWmonitor. The two important numbers are TMPIN0 is your Socket Temperature and the Package Temp under FX 8320E is the Core Temp. Socket temp is usually always hotter than the Core temp which is why your TMPIN0 shows ~40C while the Packate Temp (Core Temp) shows a much lower 20C. Two ways you can lower socket temps is to put a fan behind the motherboard socket and put a fan cooling your VRMs. That will make the socket and core temps much similar. The max temps for Vishera was known to be 61/62C for Core Temps and 71/72C for Package temps but things may have changed.

So my suggestion is that you lower the CPU Voltage shown in the MSI Control Center, better if you do it form the BIOS. At stock speeds you only need ~1.1625V but the CPU might need a little more voltage to run at it's boost speed. I would suggest setting the CPU Voltage to around 1.3V and then run a stability program like Prime95/OCCT/IBT AVX to see if 1.3V is stable to run the CPU at full load. If it passes, lower the CPU voltage a little more again. Maybe by .1 or .25 increments and test for stability once again. Continue to do this until you can't pass the stability test and just use the last lowest voltage setting that passed the stability test. This would be called undervolting but in your case I think the motherboard is setting voltages too high

Try reinstall cooler with different thermal paste.

NIce..... fans on the vrm heatsink and a fan on the socket backplate.

Okay sounds good. Well your Socket Temp was running at 66/67C when 71/72C is the Max and Your Core Temps were at 51C when 61/62C is the max. So your CPU isn't running that hot. If you want to run any cooler from here you will either have to add fans to the VRM/Socket or get an aftermarket cooler. I do not think your CPU is defective in anyway. As for AMD Over Drive I'm not sure why it doesn't show CPU temps/Thermal Margin.

I'll take a screenshot of my Temps when running Prime95.

.:edit:.

I believe Max Core Temps for FX 83XX is now 70C and Socket Temp is 80C. That's what I've read in a few places and that's what AMD Overdrive is kind of telling me non directly

Here is the screenshot. As you can see I put a box around the temperature that is important to you. My CPU is a 125W version and is overclocked but it runs around the same temps as you. My Socket temps are lower because of the additional fans I am using. It use to get to 70-80C without them when I was OCing. The single most important temperature reading for AMD Vishera CPUs is probably the Core Temps and the Thermal Margins given by AOD. You're Core Temps seem okay to me, nothing to worry about. You can always wait to see other people's responses though.

Sounds good. Yes you should not need or have CPU Voltage set to 1.4V+ unless you're attempting to overclock to the 4.6GHz range (which you shouldn't do with your stock cooler). From your first video I saw your CPU had it's CPU voltage set to like 1.13/1.14V. That's more like the voltage you should be running on your CPU. I would go as low as you go while the CPU passes Prime95 test for 1-2 hours or even 8+ hours.

It's true that AMD CPU's especially the 8-Cores run a bit warm. Even the 'E' versions you have. That being said stock heatsinks are almost never good anymore. Before I recommend a CPU cooler and you buy one you will want to add those fans behind the socket at least and even on the VRM heatsinks if you want to.

As you want your computer to be quiet as possible you want to go with bigger fans if possible as it takes slower RPMs of bigger fans to move the same amount of air. If you can add a 120MM fan between the back of the motherboard and the back side panel that would be the quietest option to cool the socket but it may not fit. Then you would want to find the quietest smaller fan to use. For CPU cooler if you're not planning to OC a Hyper 212 Evo might be just for you as long as it fits your case. I've read a few customer reviews where they state that the VRMs on your motherboard are horrible and that you don't want to OC your CPU. They tried OCing a Phenom Quad Core and the VRM ended popping/smoking and failing. Your CPU being a 8-Core would probably stress the VRM faster with a slight OC.

No worry about having any meltdowns. No video game will stress the CPU as much as Prime95. Even when running Prime95 your temps were below the Max temps with your stock cooler so while playing games it should be even lower. From seeing the AMD Overdrive video your Thermal Margin stays near 42-43C. That would mean your CPU Core Temps is running around 28-29C at Idle loads which isn't bad at all for a stock cooler in my opinion. Getting a new cooler like the Hyper 212 Evo, and adding fans to the socket/vrm will keep your CPU cool. You don't even have to do all the changes at once. Decide if you want to get the aftermarket cooler first or if you want to add a fan to the socket/vrm first. I'm using an H100i and my Thermal Margins are from mid 40s to 50C so you're temps aren't far off.
