    Yeah I get what you mean sol. Can the card have some Sorta voltage issue? Maybe it's using more voltage than it should, which in this case it'll make it a defect. What do you think?

    Well, I don't have camera here to take photo, If I could I would lend one and take a photo soon.
    But maybe you're right, I might need a bigger case, seem like the GX2 just draw hot air inside the case into its cores and nothing is cooled. Correct me if I'm wrong but isn't the fan draw air from both side (Up and down) of the VGA? Or just from the up (or down) side? I looked at two side and saw the bottom fan have a very tiny space, while the upper side fan have a bigger one.

    Oh guys. Please explain it simply and clearly, I'm not native-english speaker :respect:
    You mean my VGA has bios modded?

    I wouldn't say BIOS modded but maybe it's defective in a way where it's supplying more voltage than it should making it generate more heat. Those temps are def not normal regardless of the case in my opinion.

    well if i understand the method w1zz uses he reads vddc etc directly from the cards phases unlike the clock which he reads from the driver...if that is infact the case i took a look at his GPU-z sensor tab and he runs 1150mv or 1.15v vddc which is exactly what his card should be running at..i know this because i have the exact same cards as him. So unfortunetely that isnt the case...though i hoped it was because it would be an easy explination unfortunetely though their are alot of things that can go wrong with software reading directly from the phases itself is pretty fool proof.

    ya the card draws from the top and bottom and blows out the back....at this point...its one of 2 things IMO though CP's opinion is highely valued to me and maybe he can chime in to me it looks like your fan is failing or your not drawing enough air...and though having 1 side closed of a little shouldnt matter that much im thinking it might be a bigger problem...i mean if one side of your fan is closed off youll see a temp increase...but your seeing too much of one...so im thinking that your case doesnt have enough flow and your essentially "baking" your card. tell me do you have air on your cpu? i assume you have air...can you get me the temps of your proc? using real temp?

    Forget chickenoob your graphics card is faulty.

    Sorry but from me I can not think of other solutions

    Send to RMA if the warranty is still valid.

    So freak, my case is having *too much* air, I mean from the moment I inserted 9800GX2 into my Main board and revealed its awfully temperature, I never close the left side of the case again. You know, when I was using HD4850, its temp is incredible cool, fullload never go above 69 with 750/1100 OC'ed.
    Animalpak: I can change back to 4850 now but I want to find the reason why, just that.

    Time to think about my final option, roll back to 185.xx, if nothing change, I'm going to give this VGA an Ice cream bathing, man :wtf:

    well i hate to say it man but if you left the side of the case off and your still getting those temps than the fan is definitely failing its time to send it in for replacement :(

    Well we don't want him to Rma something if it ain't bad.


    Sol, I think now that voltage is out of the question we need to see inside his case.


    CHickennoob, can u take pic. Least with you cell phone or something? Also knowing your CPU temp will help to se if the airflow in your case is to blame

    Oh my god! I used real temp and it said my CPU temp at Idle is 6x for all four cores. But when I touch the CPU HSF, it's cool :wtf: I've re-applied AS5 also, nothing change. I wanna throw my rig away man!

    if your idling in the 60's on the cpu...either their is allll sorts of shit wrong with your system or your airflow is f@#$d

    :eek: yeah airflow is def. A problem. Chicken noon can u put a house fAn blowing straight into the pc? And monitor your temps then.

    Your HSF wont be hot, the pipes on it will be.

    What are your case fan locations? Do you have a fan on the front blowing in? and one on the back blowing out?

    And the cpu fan blowing to the back if possible as well?

    Also what kind of fans? do they have nice cfm? like 50+?

    edit: did you apply as5 as directed on their site? usually just a line or a dot. not any more than that.

    Ok I'm really tired with this GX2. Take some rest now and tomorrow I'll do the final AS5 magic. Man, I'll re-applied more AS5 and do it more carefully. I've browsed some web and some people have problem like me, but there are some say when they re-applied AS5, temp fulload stay at 8x. Sound unbelievable to me, but somewhat give me hope to rest better.
    Good night guy (It's midnight here)
    Thanks everybody for nicely supporting, tomorrow I hope I'll push the temp backward a little bit.
    PS: The thank button is disappeared now, sorry :D

    The 9800GX2 is the hottest video card you'll ever run.....2 cores directly facing each other with nothing more than a stock cooler on it.......I don't know if you've done it yet....but you should run the card without it's shroud.....shaved like 4-6 degree's off of my temps when I ran the GX2....the shroud just bakes it......you DO have an air circulation Issue though.....like CP said.....put a house fan next to your rig blowing in.....and check the temps.......I don't think anyone's asked yet.....what's the temperature in your computer room like??


    As far as aftermarket cooling goes......water's the best way to go....and also the most expensive........just buy 2 Thermalright HR-03's and do this....

    Just remember to have a fan blowing across the 2 cards to cool the memory......I was sooooo close to doing this at one time.


    Hope it helps. :)

    Ok, just caught up with this thread, chickennoob and the impression I'm getting is that it's time for you to get rid of that card, as it's just not possible to cool it down.

    The two Leadtek GX2s that I had both idled at around 65C and reached 85-90C in 3D mode. This is on a PC that never has it's side panel on, either.

    The card will run hotter depending on how stressful the software you're running is and I didn't stress them to the max. A benchmark is very stressful, so 100C sounds plausible on yours. This is far too hot for any consumer electronics to run at and in my opinion is caused by inadequate design of the stock cooler - christ man, the fan doesn't even have a 360 degree exposure to the air!

    If you get a GTX 285, which are really not too expensive now, you will get very similar performance, a whole gig of RAM visible to the game and it will run pretty quiet and not too hot - I know, because I've got one.

    I realize that you may not have money right now to replace the card, but at least you can stop banging your head against a brick wall trying to cool it down, as it's not possible without a different cooler. Having a room fan blow into your PC is an inelegant solution, but might get you by in the meantime.

    And finally, did you sort out the low performance problem? Again, having the card run so damn hot is very likely to make it throttle down a core and give you poor benchmarks.

    For something that was so damned expensive when it came out, there's no excuse for nvidia not putting a better cooler on it.

    Send the card back and spend your money on a 4870, 4890 or gtx 260, gtx 285, or Wait for the 5850, 5870 or GF DX11 parts. 9800GX2 will wind up costing more, Failure rates are higher and they run way too hot hence why failure rates are higher.

    that's pretty sick. Speaking of water, I just got a Ek block in for my 9800GX2.

    However back on topic, this might be the hottest card, but even overclocked and the voltage raised teh most I saw on mine was 79ºc, I don't know how people are getting close to 100ºc with these cards. Mine is on stock cooler.

    I would really want to see his case, i'm sure we can help him fix the issue without having to make him sell/buy another card.

    Sorry guy, but I think the problem is not Air-flow. I just put a fan blow straight into the case and the temp still the same, it's difficult to tell because I've never seen anything like this before. Paste more AS5, Use house fan, clean the HSF make no difference at all. Look like the system is burning itself, I mean maybe the mainboard is suck because even the CPU is hot and the temp is unchangeable too. I remember that I re-flashed the Main board's bios once, it was MSI Live updater do it itself, but I can't find the older Bios in MSI site (Look like they don't support this product). If anyone have it, please send it to me, thanks alot (MSI P43 Neo-F v1.2). I'm using 1.9 now.
    @{JNT}Raptor: the modded cooler look...humorous (Sorry, I don't know any better word :D) I wonder whether they are efficient or not.
    You're lucky man! Or maybe you're using an expensive cooler I guess??
    About AS5, I found it's impossible to replace the glue on those rams, they look different, very thick and AS5 seem not fit them, so I can't replace them yet. But I have to say they look so bad (used for a long time and gone bad - like that), and I bet the heat is stuck there alot. Is there any way to find a suitable replacement for those glue, something different from AS5?
    PS: The most important information here, seem like my VGA has something more than overheating, I spent 3 hours inside Stalker Clear Sky (maxed out) - this game is really stressful, just like Crysis I think. And the 100*C wall can never be broken, freak, righ? In sensor tab of GPU1, it shows that GPU1 max temp after 3 hours of gaming is 100*C and GPU2 is 90*C (The both fixed). And in sensor tab of GPU2, GPU1 max temp is fixed at 81*C and GPU2 is 75.3*C (Fixed, of course). Seem like thing is not as bad as I thought, If nothing change, I'm gonna OC my GPU a bit to make it more stressful, if the 100*C temp wall still unbreakable, I'll have to do a new adventure with this 9800GX2, something like re-flashing the Bios.
    Oh, one more information, when this VGA is stressed with Furmak, temp never go above 81 (Temp is shown from GPU1 - the hottest part)

    So now your temps are not all that bad?


    Mine is on stock cooler by the way, no aftermarket cooler or anything.

    I'm tempted to post my temps on here but it'll probably just add insult to injury cause mine is on water. Before that, my temps would hover at high 70's when folding and I learned that it was normal.
