Disabling cores, overclocking, normal temps for phenom ii x6 1055T

So I have multiple questions about the stuff I read about and did
I disabled 2 cores of my phenom x6 and the performance loss was barely a few fps on cpu intensive games
Now the temps
I use CPUID HWMonitor and I dont know what to trust, the CPUTIN temp or the cores' temps
CPUTIN is always about 15-20c higher than core temps.
Anyway, old temps were for cores idle 38~c and for CPUTIN idle 45c and under load 56c and after I disabled the 2 cores it was 24c for cores idle 34 max under prime95 testing and cputin idle 38c, prime95 46c max.
I read somewhere that AMD cpus have wrong CPUTIN temps, is that the case?
Anyway, as I disabled 2 cores, #2 and #3, my temps went down a lot with a pretty small performance change
My motherboard's socket is 95w and the phenom uses 140w, I'm guessing disabling 2 cores also helps that, right? HWMonitor still shows 140.60W on "package" cpu. Motherboard is asrock 960gm-vgs3 fx

Now my last and actual straight forward question is, if disabling those 2 cores lowers temps, wattage and loses little performance, would it be safe to overclock the mhz above 2800?
I'd rather have 4 overclocked cores than 6 perhaps because of wattage issue slower cores

Any help is appreciated! :)

UPDATE: I tried OCing to 3360mhz with cores disabled and voltage at 1.375 and its been stable for 2 hours

It's probably the 125W version. That Max TDP reported by CPU-Z is read from the CPUID... with some leeway for OC'ing maybe. Or error. The only way to tell for sure is to remove the cooler and check the printing on the CPU's heat shield that starts out "HTD55T..."

Always watch core temp. Try a different app if that one is too confusing. I like HWinfo.
I doubt that 6-core is a 140W CPU. There were 2 versions of the 1055T as I recall. A 125W version and a 95W version. I've never heard of a 140W version.

So first be sure which you have. If the 6 core is now a 4 core, the wattage will drop, but OC'ing on that board will shorten its lifespan. Poor 3 power phases and no heat sinks on the VRMs.

Are 27 idle and 45 max under load safe temps for cores?
CPUTIN is 61c though, which one to trust since 62c is max temp for 1055T as i've read somewhere
If that's too hot i can up the fan speed, would this really degrade the cpu or was it just a warning that it will fail faster than normal? I'm damn ready to take the risk for getting instead of 40fps, 60fps in gta5 and fallout 4 :D

One more question, if the 4 cores are overclocked as well as 2 are disabled, this will in kind of a way prolong the motherboard's lifespan? as in less wattage? (anyhow i managed to find a good clock speed that doesnt go above 55c and doesnt crash)

Any time you can lower wattage of components, it is a good thing. But overclocking the 4 cores may be as demanding as all 6 cores were at stock speed. More so if the 4 cores run at a higher usage than the 6 were. But your max temp of 55 is excellent.

Any ideas or suggestions? I was sure for at least a year this was a 125w one though :D
