    Well... as magically as it fixed itself, it suddenly unfixed itself.

    The fan suddenly shot up while on the windows desktop and has been full blast ever since.

    So should I bake it for real lol?

    Sily thought but have you pulled the card out and cleaned out the HSF and applied fresh TIM? Sometime's i have even found simply pulling the card and reinstalling does the trick, for what ever reason i have no idea :eek:

    Yeah, that's next on my list - I'll probably run to fry's and grab some new paste.

    I wish.

    It doesn't obey any fan controls, in any program, it always runs at 100%.

    :(

    Is it reporting that it's really hot again too?

    I think its safe to say that the sensors/fan iC are fubar ... baking it wont fix that

    I took it out, blew it out and re-seated it and now it works again.

    /facepalm

    ... Just like baking my 8800GTS in an oven to fix memory errors from overclocking it :)

    Jokes aside tho I didn't see anyone bring up one of the more obvious possibilities - that the thermal compound has dried up / failed and that the gpu really was reaching over 100 degrees.

    I'm not saying this IS the fact here but I have seen it before, buddy brought me his pc said the fans where going crazy - so I pulled off the gpu cooler and the thermal compound was all dust...

    Naw, you'll see in my screenshots that it's over 1000 degrees, it only shows 127 cause the counter is maxed out.

    You're welcome?! :) lol Hopefully it doesn't revert back to being finicky :eek:

    First thing i always do/reccomend when having GFX trouble ;)

    XFX 5870 Fan going 100%

    I was following this thread cause I just got an XFX 587XZNV and the fan started to go crazy as well with >1000C temp and maxed out at 127C in CCC. Running Furmark fixed it for now and everything is back to normal however it did it a couple of times already even though I applied new Arctic Cooling MX-2 on the GPU and did a good cleanup.

    Nonetheless, I bet it'll do it again sooner or later. The good news is the card is still under warranty so I can send it to RMA if needed but still, if I can avoid it....

    I'll keep this thread posted.

    Thanks for the tip!

    1000c lol if it was any-ware near that hot you're case would be slag that's more then hot enough to completely liquidfy steel or even Cast iron
    also MX4 is wayy better

    Bow-boooooww. I work with steel and the flame that comes out the oxy cutter is about 3000C and it takes a few seconds to melt.

    Of course it wasn't "real" 1000C

    Just the sensors which for some reasons were out of whack...
    Nonetheless, Furmark "fixed" the sensors, maybe they need to reach a certain level of temp in order to reset?

    Also MX-2 vs MX-4...doesn't really matter, just got a stock load of MX-2 so I might as well use it :)

    The point was that even with a cleaned card, the issue occurs randomly. Either way the card is under lifetime warranty so if it can't be fixed I'll RMA but it's a pain... :banghead:

    temperture wise theres little difference between MX-2 & 4, though MX-4 is easier to spread, Kinda like those little tubs of butter that the hotel staff leave out at breakfast time. It will spread like mayo so long as they havent just pulled it out of the fridge.

    it irks me to no end when the butter you are trying to spread on the toast is destroying and tearing the toast to shreds before it even has a chance to get in your belly.

    Mx2-4

    That's why I don't spread MX2-4 on my toasts...:p

    I usually put a pea size drop in the middle of the GPU/CPU and it seems to work well for me. On this particular card I get 45C idle and 71C average load. Not bad with one fan.

    :D

    those are some pretty decent temps as far as stock cooling goes. my 6970s used to idle at 53'c till i got a bigger case for them with more breathing room. my load temps are higher by a decent margin though as XFX's warranty wont allow me to remove the stockcooler to replace the thermal paste.

    so depending on ambient temps my GPUs sometimes run close to 90'c with the standard automated profile, otherwise i just manually set the fans to run at around 35-40% where they are clearly audible but easily get buried in the sounds of explosions while play BF3

    XFX warranty

    I guess it's not bad temp. Fan is ok up to 60% then becomes loud (4400+ RPM at 100%). Changing the TIM dropped the temp by 12 degrees or so at full load.

    Odd for your card that changing the thermal paste would void the warranty. I've read threads on this and the XFX guy was saying that you can do whatever to the card as far as you don't damage it physically and return it for RMA in its integrity. People were worried about water cooling or third part heatsink and because you need to clean/re-apply the thermal paste it seems like it didn't matter for the warranty.

    Now, if you break a seal in order to open your card to reach the GPU, it's another story. You should contact them and ask for more information. ;)
