The install went great, any problems I ran into were "user error". A missed screw here, a totally-forgetting-to-plug-the-CPU-cable-back-in there...clearly I should never be a surgeon. The instructions for the cooler basically beg you to use the pea/dot in the center method of applying the paste, so I went with that.Let us know how that goes, it should drop your temps at idle down to high 30s or low 40s if you've done it right. Once you're seeing that it's time to run through your stability tests again and see if the problem is gone.
Those temps are looking way lower! Let me try running Memtest.
