Initially it was gpu>gpu>cpu as that would ease bleeding the system with the case upright, I tried changing that to CPU>gpu>gpu with only 1-2c difference tho. Guess the pump is working and doing it's job

Have you tried to run 1ghz at 1v yet? Also check your load voltage with newest CPU-Z, could be spiking very high under load. I wouldn't trust what HWmonitor says about the voltage, it never shows the actual voltage like CPU-Z does.

Nope didn't get that far, I HAVE however been tinkering around
Temps dropped to 67c under load in Prime95 now, still high but aslong as it doesn't shutdown due to the thermal protection it'll prolly be alright. Who cares if it burns out in a year or two anyway, prolly be swapping this puppy for the Bulldozer when time comes!

Now, the problem it seems, was the LLC. It was defaulted at auto, which does, god knows what. I tried disabled, then normal. At normal the vcore barely fluctuates, no more crazy 1.68v spikes, yay!
Seems like I just got a bad sample for OC'in, I still have to run this one at 1.51v or it'll crash the workers in prime95 within a few minutes :/

Thanks for all your fast input, much appreciated!

On a final note, I would like to mention that the max temp of those is 55c before the silicon degrades. I don't think it'll even last a few months at 67c.

I don't go off of the CPU temp, only the core temp. 67c under load on prime is your CPU temp? Mine is around 64 as well, but never tops the mid 40's of core temp. That is what I think matters, not the temp at the socket. I could be wrong, but like I always say, I refer to the engine of a car, the outside of the engine will be hot, but if the coolant INSIDE the engine is within spec you are ok. But that's just my viewpoint...

And I actually have my LLC turned off, but with my board with it off, it requires higher voltage to boot, but under load the voltage drops and helps keep the temps cool. So just idle/browsing the web my voltage is at like 1.5-1.54 whereas under a heavy load it is at 1.46-1.48.

With LLC enabled, I only needed 1.48 to boot, but under load it would jump to 1.53-1.56. At the same speed. So I disabled it.

You may not have the same experience but that is what worked for me.

Hope that helped.

Uh, no. 62C is the maximum safe temperature for air, 55C is where some Thubans start to get unstable. You can easily run 70C for years, and still have next to no degradation. I've seen many cases where someone has been running Phenom II's in horrible conditions for years, yet they are still fine.

I would get a new board and maybe shortan some tubes on that loop.

Yup, this one has been running hot ever since I got it when it first came out, I think it's one of the first batch of 1090T BE's.
Doesn't matter if it lasts 2 or 10 years either TBH, I'll be running something else by 2 years time anyway

My recommendations:

a) reseat the CPU cooling...you never know (not saying you don't know how to seat a cooler)
b) try a different cooler
c) try undervolting as much as possible to reduce heat

not sure why it'd run so hot, but stranger things have happened. could be a manufacturing defect.

that CPU temp is actually the VRM's and/or CPU surronding area temp. (CPU temp sensor is on the motherboard.)
-may be a bad VRM/heatsink contact.
-make sure that turbo core is disabled
-cool the back of your mobo(CPU area), if its possible
-dont use AUTO for CPU voltage
