The only temp that matters, in your case, is the 8350 "Package Temp". That should be the Core temp of your CPU. That value should not pass 62C.
CPU temp is a sensor in the socket. You can ignore it. Raise the value enough so it doesn't complain until Package Temp is 62C.

Is there proof of this anywhere?

Just wondering because the thermal protection doesn't kick in till 100c.

And my 8320 has seen sustained temps well north of 80C with no apparent ill affects.

Don't worry, I run hot too. Same with my Ph II. I won't recommend to someone else to do the same though, I accepted the risks of doing things this way, and it's up to them to do that same if they want to.

Always have, always will. Push it to the limit! I've never fried a CPU from overclocking (or overheating) but maybe I've just had good luck.

Too bad I didn't transfer that luck to my CPU selection - My 8320 basically refuses to overclock at all and have prime95 not get errors. Seems like most on this thread had way better luck in that respect.

Is it just me or does this scream "delid me" It makes it sound like IHS is extremely bad at transferring heat.

Neither have I. I ran my 920 at 90c under full load and rendered in Blender non stop. Also ran it at 1.5v+ the entire time. Never a problem. Same with my Opteron 165 at 1.6v+

I finally got my FX-8350 stable OC at 4.66 GHz, 10 hours on Prime 95.
I'm stopping it there because package temp peaked at 63°C which is higher than it should be.

My successful settings are 233 x 20 clock . NB and HT both at 2330 . Memory at 1864 (8x233) . The CPU NB was 1.25V, CPU voltage 1.4125V , LLC on high. I'm on air, running NH-D14 .
I will hold off putting this in the table just yet because the CPU temp is too high, especially for summer time.

For those running a Gigabyte 990FXA-UD3 rev 1.1 with BIOS F9, here are the full BIOS settings :

CPU clock ratio 20 4660
Northbridge freq x10 2330
CPB Disabled
CPU host control Manual
CPU frequency 233
PCIE clock 100

HT link width auto
HT link frequency x10 2330
DRAM EOCP profile1
set memory clock Manual
memory clock x8 1864

voltage auto
CPU PLL normal 2.5V
DRAM voltage 1.53V
DDR VTT normal 0.75V
NB voltage normal 1.10V
HT Link voltage control 1.25V
NB/PCIe/PLL Voltage Control 1.85V
CPU NB VID +0.075V 1.25V
CPU voltage +0.075V 1.4125V

Load Line Calibration High

BIOS boot OK
Windows boot OK
IBT OK

max temp 63°C

Prime 95 10 hours OK

Sadly, I just lowered CPU vcore one notch to 1.3875V, and prime95 failed immediately. So this might be the minimum vcore required for the CPU. Not sure how I'm going to be able to lower the temps.

I seemed to peak with the temps at 43 on socket 29 on the core, they actually went down a few degrees instead of raising. I cannot see the temps raising too much over your 21 hours lol certainly not to your temps anyhow.

Thanks for posting this. I notice that your CPU vcore is only 1.23V in that pic. That is well below stock settings which is 1.3375V minimum and I think it rises to close to 1.40V under Prime95, even at stock .
The lower voltage would explain your much lower temp.
Do you have any kind of power saving features enabled in your BIOS ? C1, APM, C6, CnQ, etc ? I am testing my OC without any of these.
Also, I'm running Windows on the "high performance" power profile.

As for running Prime 21 hours, my experience was that it did rise higher over the long run. package temp was maybe 42°C in the first hour, but after 21 hours the peak was 45°C. My ambient temp is about 22 - 23°C, so I don't think it's very likely I could ever achieve your 29°C package temp under Prime95.

There are other things that could explain my higher temp, I have multiple GPUs, one additional PCIe SATA card (8 ports on the mobo not enough for me).
I have 4x8GB RAM which will stress the chip memory controller more with Prime95. That can raise temp. Due to the GA-990FX-UD3 mobo design, two of the CPU sticks are right under the NH-D14 .

My HAF XM case has two optical drives, two SSD (in RAID), two HD (in RAID also). Though I don't think the drives put much heat.
The case is maxed out on fans also (added a 200 mm side fan).

Oh OK, well, I don't do games, so that's not going to mean much to me.

He always try to prove people wrong whenever he thinks they are lying xD im just hitting back with screenshot proof lol. I know its sad but thats how he made me feel sadly.

Well I hit the 10 hour mark at 4.66 GHz, didn't take screenshot though. Temp was too high for my taste.

The only thing I'm saying is people shouldn't ignore the results of prime95. I'm not sure what any screenshot can do for or against this argument.

sort yer own bloody cooling out!!!
my stock run will come shortly just to prove you wrong like you try to do everyone else.

Thanks for posting this. Actually I was reading the wrong mobo sensor, the socket temp is not 56C, that was the NB temp. HWmonitor does not do as good of a job on the Gigabyte mobo unfortunately.
It just says "TMPIN0, TMPIN1, TMPIN2" for the motherboard sensors. Not CPU and mainboard like on yours.

Your package temp is 40°C at peak while mine was 45°C. That's a meaningful but not huge difference.
If I run Prime95 just an hour or so I will not hit 45°C, that was only the peak after the overnight run. Maybe other factors can explain the differences.
