1. When you run one of those mini-loops you have removed the air from the cpu socket. Air that overflows from an air cpu cooler. That happens to everyone.
2. There are some that have VRM heat issues and that can also come from the air flow that was there with an air type cpu cooler.
3. So just adding back the missing air flow which resulted from going to a mini-loop may in fact be the real answer.
All of that said it is best to test to see what really is going on. This is what we need to see for sure and a real good starting point.

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.
