Your PWM temps seem kinda high, this is mine, uptime is in the task manager, 76 hours since a reboot crunching at the settings seen, ambient is ~70F, so 100% cpu load on all 4 cores, Vcore is set to 1.4875 in bios but always shows as 1.5, DMM show 1.49, so stick with that as my true reading. Boinc WCG does not stress quite as much as Prime, but it is pretty damn close.

I will have a transpiper in my hands on Monday, so will give it a burn in and see how it does compared to the stock cooling which I am using now on the PWM. From what I have been told, above ~45 is danger zone on these, so I am just skirting the limit. (all in red due to fan settings I have in the bios)
