    Post Computer shutting down randomly

    ...due to high temps, or so it seems.

    While playing Minecraft, I noticed temps going around 70-73C! Once I shut that or other games down, it idles around 20-30c. My wild guess is, it should not run this hot.

    The BIOS settings are default, the heatsink is stock, and nothing is over-clocked or tweaked.

    AMD FX 6100
    MSI 870A-g554
    American Megatrends v 17.17 BIOS last update Jasn 13, 2012
    Radeon HD 5770

    From looking inside my case, it does not appear anything is obstructing the fans, but it does seem like the components are somewhat crammed because of the massive size of the video card.

    I went ahead, and cleaned the heatsinks, fans and other components with canned air, and it did get rid of some dust bunnies, but did little to cool things down. At those temps, it is doubtful a few dust bunnies it would get that hot, but then again, I have seen a few dead systems from the lack of cleaning.

    Ideas would be nice.

    Front fan blowing in, rear fan blowing out, now the side fan one has to experiment to find out whether blowing in or out runs cooler.

    Also, you may want to redo the thermal compound using these instructions.

    Yes, a air pocket in the thermal compound can cause that heat to act like that.

    Oh, gosh I did not think about the thermal compound. I did remove the CPU before, and did not re-apply thermal. Yes, I know that is generally not a good idea.

    I just updated the BIOS, and did little for the temp problem. AMD suggested that, but they said it is probably better to send the chip to them to have it checked. No, they did not suggest re-applying the compound, lol It would suck to have to wait that long to get it fixed, but if it is that, I will.

    In the meantime, I will rule out the other stuff first.

    Yep, you have a air gap/pocket that is causing the overheating!

    I use 90+% alcohol to clean off the old compound. The follow the instructions for applying the new. Should square you away.

    Shall we say learned the hard way.
    Because of the temps you have hit, I think I would follow AMDs recommendation too.

    I just ordered some thermal paste. I am tempted on getting one of those big ass heatsinks, but that may be overkill when I am not planning on overclocking.

    May not be overkill either. Been that route more than once.

    Yesterday, I was watching some videos on the overheating problem. On the related videos, there was a computer in a fishtank with what looked like water. Complete with rocks, bubble makers, the works.

    I must of been living under a rock, because it said mineral oil cooling is nothing new. It looks hella neat too. I might try that someday, but upgrading must be messy as hell, lol

    Mineral oil has been around for years. Since it is none concutive, it was even used back in tube days for cooling.

    I went ahead and ordered this too:

    Hopefully that will fix the issue, if not, then it is time to send the chip in to be checked. If it is not the chip, could the motherboard be the issue? That is later on when other stuff is ruled out.

    Update: I installed the new thermal paste and heatsink. The new heatsink is the one pictured above.

    I am running Minecraft, and so far, the temps have been around 30-35 c so far. I will run Saints Row the Third and see how well it performs then.

    At any rate, when installing the new thermal paste, I found the source of the problem. The stock heatsink came loose and was dangling there. yeah, so that was pretty dumb to overlook such a "tiny" detail. Oh well, I might have shortened my CPU lifespan significantly, lol
