That should work. That being said, I would like to hear from someone else to weigh in on this problem, maybe there's something I'm missing.
My logic goes like this: It's unlikely that your CPU is hitting 209C, without consequences, so that has to be a false reading... created by the PECI (well, that's what it's called in Intel land) logic, whereas there's a bi-dir overheat signal, that can be triggered by the CPU, if overheating, or the chipset, to throttle the CPU. My understanding is that when the VRMs overheat, on most AM3+ boards, they signal the CPU to throttle, by programming the temp sensor or whatnot signal, to show 200C+ temps. Which would not ordinarily be reachable by CPU overheating alone.
Plus, your HWMonitor shows one of the temps near 90C+, that's probably the mobo temps (VRMs).
Does anyone concur with my logic?
If that board has VRM heatsinks (which I doubt, given the temps), but if it did, you could zip-tie a 120mm case fan in the region, and maybe cool them down that way.
