So having a very odd issue, this CPU reports overheat and shuts down the computer in my Gigabyte 790X-UD4P board, new thermal paste, new cooler master master liquid 240, I tested with my X2 7850 temps are 41C at load, tested with X4 9750 temps are 48c load, even pulled my x4 965 from a different retro and it's load is 47c, so I put the x2 555 in my asrock 970 extreme4 and no overheat temp reading fine was thinking faulty temp sensor but then back into the 790x it turns off within 2 minutes due to overheat. Just trying to get it to work as a file server for my retro collection so my primary nas no longer requires smb 1 on and storing data for the retros can be on this. Any ideas? I need support for server 2003 so much newer hardware is out of the question as it has to talk to 3.1 through XP pro.

And before anybody asks I'm running the latest bios which has support for this CPU and I'm very confused. I also tested a 1090t and it also works

I just don't need that much compute power but the 6mb l3 are useful for file xfer because I did test my X2 250 and my X2 7750 both at 3ghz and it was faster with the 7750 and I'm guessing due to its 2mb l3 so 6mb l3 has to do better handling multiple xfer requests, but I never stress more than a single core.

Difficult to say what the issue is.

I only have 1 workaround to suggest, if this doesn't work, i'm out of ideas.

When you have your CPU installed in your Gigabyte MoBo, don't plug the AIO to CPU_FAN header. Instead plug it to SYS_FAN header. And in CPU_FAN header, plug any, known to work, 4-pin PWM fan.

It could be, that for whatever reason, Gigabyte MoBo doesn't like that AIO and kills the system after some time. (AIO pumps sometimes doesn't send RPM feedback to CPU_FAN header, triggering the "fan failure" safeguard and shutting down the system). Some BIOSes even have option to disable CPU_FAN header fan failure safeguard, when running AIO.
But when you have actual working fan plugged in the CPU_FAN header, the safeguard doesn't trigger and system stays on.
