Come let us reason...

The idle temp of the CPU hovers around 40 odd degrees and 50 odd under load. But IIRC I was also getting freezing with my old Phenom II X6 cpu that used to be in the system.
I dont get a BSOD, any crash dumps or logs other than unexpected reboot. I tried driver verifier but It still freezes without creating a dump, although it seemed to be harder to purposely crash the system whilst it was enabled.
I must say that with my own problems, I have not paid much attention to this post other than knowing people like Mr. Scott have done this stuff for more years than many of the posters in here have even been around. He thought heat and I simply agreed. But read on below.
When I see an idle temp of 40c odd degrees, I have a problem in my thinking. I know good contacting (even air coolers) will show temps below the temp of the room the computer is in. We know this cannot happen but when that temp which should be showing an errroneously low temp does not show the low temp...well there is almost always a cooling issue.
You also say that the problem was occurring to some extent even with your old Thuban 6 core processor. You have changed >>
I have tried replacing the PSU, GPU and swapped the HDD for an SSD. It has also had a new CPU. When I see that many changes and the problem is still there; I always suspect more than one thing.
Hard crashes with NO BSOD reports or dumps, almost always mean a problem with power, heat, or ram and generally in that order of most likely to happen. IF you changed to a decent power supply, then we can rule that out as a cause. That brings us to the next two that I have seen give hard crashes. The heat and the ram. Now you say you have ordered a new cpu cooler but you do not say which one. Would have been nice to know if you were just buying something else less than optimum. But onward.
So in theory we have handled a possible power issue. Theoretically we have a Cpu Cooler on the way to apply toward the heat issue. That would leave us with a ram problem to perhaps have to investigate. Time will tell.
What bothers me is when the cooler comes and is installed accurately just about everything has been swapped out but the motherboard. I mean look at what is changed. You have addressed drivers it seems. So why the crash under heavy render load? There is something a problem before the FX processor and a problem not yet addressed with all the hardware changes. We will see what happens after the cpu cooler change.
I would suggest this after you get the new cooler mounted so we can see what is going on inside your case to a greater extent than we have now.
This is what we need to see for sure and a real good starting point.
Normally during setup and testing we disable C1/E, C6, Cool N Quiet, APM, TurboCore and in windows performance manager itself we set to "performance" mode. ALSO if you have HPC in bios you would ENABLE it. That way there are not "other" settings messing with the overclocking process. Some of those settings are not available on all models of cpu but where in evidence we disable for setup of overclock process.

And this is screen capture of HWMonitor (free version) from CPUID com
HWMonitor has been scrolled enough and large enough to show Min/Max of Voltages and includes the CPU CORE TEMPS / "package" temps fully visible. Latest versions of HWMonitor show the CPU Core Temp as " a Package Temp" and is only shown as a single temp since there were never multple, individual core temp sensors anyway.
This capture is made of HWMonitor after it has been open and running on the desktop logging Min/Max temps and voltages while Prime 95 was running Blend Mode test on all cores for at least 20 mins and then the capture of HWMonitor was made and it shows the Min/Max temps and voltages before P95 Blend was started and while running P95 Blend mode and gives much greater insight into how the system is performing without guessing.
In order to attach screenshots of INDIVIDUAL images as suggested, first crop and capture the images with Snipping Tool found in Windows Accessories or equivalent. Then click on Go Advanced, a button at the bottom of every new post window. Then click on the little paperclip tool at the top of the Advanced post window when it opens. Clicking on the paperclip tool brings up the file browser/upload tool and the rest is fairly obvious.
