    "Motherboard" is often southbridge die temperature. 40C doesn't look harmful in any way.

    yeah 60C is about enough to start causing that burn sensation on the skin XD

    Don't we all have a rough idea of temperature? If someone has fever, you can tell if it is 100 or 102 degree F just by touching their forehead or neck. It is similar with computers and namely anything in the range of temperatures that we work with every day just like boiling water, cooking etc.

    If you can find me a person who can consistently tell me what's at 60c and what's at 80c I would be mind fucked.

    Yes I am. :) That is because one fine day, I was fiddling with my computer. What I did is I removed the fan of my heatsink and ran prime 95. XD I was assured nothing would happen as it will take time for the CPU to get hot and reach its damaging temp and in the worst case thermal protection will kick in. I watched the temps rise to 50-60-70-80 and kept touching the heatsink with several fingers randomly. In one word I felt it and that's why I can tell you whether its around 60 or 80. Finally my adventure stopped as I got a BSOD and then removed power from the system immediately. This was done 2 years back. To this day, the CPU still works good as new and in good condition(see the CPU and IMC OC in my specs). :)

    Wether or not we're all human thermometers is really irrelevant. The OP has the exact same board that I have in my HTPC. I stick by my original post that "his" 8350 is too hot and thirsty and that's why his board is heating up. Additional cooling on the VRM/NB section and a fan placed behind the mobo will help alleviate this issue. This is a good board and runs my 965 beautifully. I have had my 6350 in that board as well, without the overheating that I saw from my 8350. Like I said previously if someone can run and 8 core in a 4 phase board they got lucky in the silicon draw. One thing I do know for sure is I can run F@H 24/7 with my sabertooth, have 2 GTX580s and my 8350 @ 4.7 and not worry about anything blowing up.

    Number of power phases is not a major thing in this regard. I can bet if I put in a 8350 in my board and overclock and stress it 24/7 nothing will blow up. Theoretically, a 965 and a 8350 has the same TDP. So I don't see how it causes a diff in VRM temps. Obviously higher end boards having more and better power phases with better cooling system will heat up less. Sabertooth is a premium line up of boards made to last long and guaranteed to be stable in extreme situations from Asus and OP has got a mid - high end mainstream board. You cannot compare those two series.
    The thing is those components are known to heat and that is why heatsinks are provided. The manufacturer knows better than us in what's good and what's bad and they test it enough before releasing it in the market. The fact stays the same : With the implemented tech, the board works well enough for enough torture.

    its relative, so you will never be accurate. put your hand in boiling water, then in hot water and your hand would feel like freezing.

    First I would like to say that the number and quality of of the phases plays a huge role in the amount of heat that's generated and running a borderline board hard for any period of time , I wouldn't be surprised if something finally gave out.
    If you used a 4 phase board and an 8 core CPU without OCing. The way that AMD has intended it to be used, yes you could get away with that.
    Once you shut off all the green stuff and start overclocking all eight cores you are ouside the manufacturers specs and all bets are off. Then put a heavy load on it. The manufacturer didn't have that in mind when they included the 8xxx in the support list. As far as the TDP rating, either AMD mislead the Mobo suppliers or they're just flat out lying. How can you go from 125w to the 220w rated 9370 just by raising the core speed 400MHz. C'mon these things should've been rated higher in the first place. Even Giga realized what was going on and with the rev3 boards started throttling the CPU for their own protection.

    You didn't notice I used different fingers. I am aware of the relative thingy. Basically I have good knowledge in physical science not just academically but practically too and am well known for that. :)

    Agreed. But there is a safe limit. If a board supports 125W CPUs, it does not mean that it is capable of handling exactly 125W only. I had a 4+1 phase board - The Asus M4A88TD M-EVO/USB3. It did not support FX CPUs at all. But I crazily overclocked my 955 at 3.8-3.9 GHz along with the IMC at 2.8 GHz. NOTHING EVER HAPPENED until I was cleaning it one day and placed it on my bed sheet and it died because of ESD which was 2 years later. One of my friends also have a 4+1 phase board- The Asus M4A88T-M and his CPU is clocked like mine too. His board is 2.5 years old still running butter smooth. No idea if AMD lied on the TDP of FX because the company could have been sued then.

    and you didnt notice that your ambient temparature is constantly changing and that your body is constantly adapting to that by increasing or decreasing your metabolism(unless you are a cold blooded organism).

    I have a PII 965 that has been OCd as well but it is nothing like a six, eight or even a four core FX. With the same board as the OP and my 8350 clocked to 4.4 I was having serious heat issues with the socket. My core temps were fine in the low 40s but my CPU/socket temps were nearly 70°. So putting additional fans on the VRM H/S and a fan behind the mobo brought those temps down. If a H/S is getting hot that means it's doing it's job. The only way to help it is by increasing airflow. The same CPU in the Sabertooth at higher clocks doesn't need the additional cooling since it has more lanes to handle the current.
    So being "good" in physics it should be easy to understand that putting too much current through a conductor causes heat. Spreading that current out causes less heat.

    I don't think human skin is a good conductor of heat and bones are definitely not. That little bit of sensing heat is negligible to the variation of metabolism that is always happening. Put it this way: You can put your hand on a 70 degree C water. It will hurt but it is definitely possible. Gradually, keep on increasing the temperature. At one point, your hand will not tolerate the heat anymore and you will remove it. Had your body adapting it by varying metabolism, you could have kept your hand on practically any temp that way.
    Ps. this is not a biology class. :p Moral of the story is I can feel temperature ranges that I work with in real life and and I have proven myself to be true various times and my friends agreed too. What I did was I was touching the heatsink and did not look at the monitor screen. I told my friend an estimate of the temp that I feel. He checked with softwares and I was real close and the range I told in which it lied was perfect.
    These things are relative to human beings. I would not be surprised if you can tell at what RPM(a range) a fan is spinning just by looking at it. For me, I would not have a damn clue. :p

    As I said forget the Sabertooth. Its built on a different tech and has got better MOSFETs and chokes apart from more lanes. When you have to compare, compare a 6 phase high quality board which the OP has to another 8 phase board which costs the same and is available from other manufacturers maybe. More lanes does not always mean less heat will be produced. It may be like that the cross section of the copper conductors on the board with 8 phase is much less than what the 6 phase board has. Its all in the math. Maybe the 6 phase board used better copper, optimal cross section. The thing most important here is the quality of the MOSFETs used and their power delivery and the quality and impedence of the chokes. It is not the board(lanes) which gets that much hot here. It is the MOSFETs and chokes which get hot- the reason they are cooled with a heatsink. So a lot of other things counts apart from the number of lanes which is dependent on the number of phases.

    The biggest example are 8 phase MSI boards and 6 phase Asus boards. MSI ones are well known to get off with a bang even on a slight or no overclock whereas Asus ones survive good enough on a decent overclock.

    The point I want to say is at the mainstream market, it is one of the best boards available. So if it gets hot, no other board at that range would be cooler unless you get a Sabertooth or ROG series. The tech is like that and there is nothing to worry about. I would not consider a 990x chipset board to be "cheap".

    The only one that did work was the UD3 and Giga screwed it with the Rev.3. It was almost perfect for the budget minded. The only real "mainstream" board that had an 8 phase supply. I've looked at the Asrock ext4 but it kinda worries me. I wanna pick something up cheap to mess with.

    I think someone might find a way to do a BIOS mod for the Gigabyte rev3. Give it time. As for the Asrock extreme 4, I think that is the one de.das.dude has so you may consult him. :)

    Crazily overclocked to 3.8/3.9...roflmao you indian college kids are always right aren't you? I give up you obviously greatly out know me heck I have never touched amd cpu's in my life or diagnosed throttling days before the owner finally realised what was happening.

    Didn't get you. As for the overclocking part, getting 3.8 - 3.9 GHz from a 3.2 GHz unit with a stock cooler is indeed crazy. Talking about throttling, temps stay under 60 degree C so no question of that. It has been overclocked like that for over 2 years so I don't know in what way I am wrong. The discussion was about stability in lower phase count boards. And my point was overclocking a 125W FX on a 6 phase AM3+ board is equal to overclocking a 125W Phenom II in a 4 phase AM3 board.

    There is no more discussion left and I think I justified myself enough in my previous comments.
