Ok, so your temp readings are completely wrong then. Blend is not used for thermal compliance testing. You want to use Small FFT. That is the Gold Standard for testing thermal compliance. Not "Smallest FFT". Not "Large FFT". Not "Blend".
SMALL FFT. Then, disable the option for AVX2 and then AVX after it becomes un-grayed.
Run Small FFT for 10-15 minutes keeping a close eye on temps during this time. This will give you your thermal baseline from which to make configuration or cooling adjustments. For your CPU while running the Small FFT option in Prime 95 you do not want to see any core temperatures exceed 95°C MAXIMUM. Preferably you'd like to see it not exceed 90°C during this test. It is always good to have at least a small buffer between your actual maximum thermal response and what the recommended maximum actually is. Then, if you run applications or games that you know heavily use AVX instructions, you can configure an AVX offset in the BIOS for most motherboards and then if desired you can re-test without disabling the AVX option in the Small FFT thermal test. But for determining your baseline you want AVX disabled and you want Small FFT so that you are testing using a STEADY STATE environment.
Other tests in Prime are not steady state and will offer misleading results as a result of that.
No, that is not right. MANY boards will "work" with a bent pin or two, but it absolutely is not working "right" when that is the case. If the pins are not 100% straight and making proper contact with the correct points on the CPU, and if there is ANYTHING at all which might indicate errors, erratic behavior or other problems, you can be sure it is likely a result of the bent pins on your motherboard. I mean to say the SECOND you see ANYTHING that makes you go "hmm", I'd go straight after the motherboard because it WILL almost certainly be to blame. It is extremely difficult, unless it is only just barely deviant, to straighten even one pin on a motherboard pin bed without breaking it off below the level at which you can see where it actually makes contact with the traces between layers of the motherboard, much less "some" which I assume means "several". It's possible, if you are very careful and if they were only barely bent, but any significant bending is really hard to correct, but again, depending on how badly, it's possible. Maybe you got lucky.
But I assure you, the CPU "seeming" to work fine, is not an indicator of whether or not there is still or was a problem. It matters, MUCH. There is NO scenario where it is ok for pins to be bent. Not even ONE pin. ALL pins must be exactly where they are supposed to be or you WILL encounter problems at some point, or even very often. It could be something like the memory not wanting to run at full XMP speed, or certain DIMM slots won't work, or random errors that you can't figure out, but something will happen. There is zero doubt about that.
