    the cards barely a month old. But i'll try it. Yeah it Could. Not to make sure you understand about the splitter. Its the another 4 pin attached to the connector . http://artpad.art.com/gallery/?j02g6vw15no Is this for dual video card support only or should I plug it into my psu also? From what you said it sounds that I shouldn't Just verifying. In a bit i'll turn off my pc and pull it out and blow the dust out of it like an N64. Maybe i'll see a slight improvment.

    Yeah, that splitter is just to give you an extra connector if you're out.

    If the card is only a month old then i'm sure it's not clogged with dust. I wouldn't bother pulling it out.

    I don't know how hot Nvidia cards are supposed to run but my x800 was around 72 at full load so i don't think you're THAT hot. Once when my heatsink got clogged it got into the 90's before my motherboard started beeping and i didn't experience any slowdown at all, just warning beeps.

    Your temps are most likely the result of your room temperature being 88 F. Your heatsinks and fans are only as good as the air thats blowing through them and 88 is pretty damn hot.

    Also, do you use any programs that let you control the speed of your video card's fan? I know that ATI tray tools lets you control the fan speed of ATI cards.

    My X800XT ran about the same temps, but with an aftermarket cooler (Zalman VF700-Cu), I managed to OC it almost 20% and keep it around 59-61C load. Thats how much difference a good aftermarket cooler can make.

    Good call there Caxus, I thought it was kinda clear what thermal paste is. Either way, if D@nny had read the instructions for use, he would've found out how to use it anyway :p

    I love the animation, but you could've saved us some time by just uploading a pic :D

    Temps for 6800s seem to be in around the same area, probably not a problem, but you're just not used to seeing temps in that range, since CPU temps don't ever go there unless there's a problem.

    D@nny, I don't think that's too hot, considering where you live and the card in question. I have a 6800 GT here and it's idling at 62degrees celcius right now. I think, though, that that's because I'm only powering it with a 305w psu :eek: Kirock even told me it'll eventually blow up! Anyway I think you could just get a case with a grill on it, and move the tower into a more open space if you can, see if that helps. What kind of power does you're psu have? I think mine(and yours maybe) idle so high because they're only just getting enough power.

    since you live in a hot area, you should have good case cooling. if all you have on your case for cooling is the fan on the PSU, then that's not enough. you could add something like this to your case. they mount in an empty PCI slot and can help suck some heat off of your video card. it's not a replacement for good cooling, but it may help [​IMG]

    its good to put that in, but make sure the fan isn't anywhere near another fan thats also sucking in air, or you'd just do yourself harm.

    It would be a better idea if you can get one that blows air in instead, but those are hard to find.

    Thank you for all your responces and help. I might go and purchase the zalmax fan anyways unless you guys think that 79-84 * temp arn't really hurting my card. Only problem Ican think of is that when I buy it the zalmax fb 7000 (sorry it's early)won't have enough room around my video card to fit it in properly. I do have any extra slot but it's marginally covered by this chip beneth it and it's all the way at the bottom. But I think it's safe to rip out since its like a phone line connector. Paranoid guy I think you hit it right on the spot too. My psu says it has a max for 295.4 watts. So If I get a new PSU and open a window once in a while my problems will be solved. Anyone know how many watts will be needed to power the new cpu's and gpu's coming out next year? (goes newegg shopping)

    models like the pictured one are pretty short and wouldn't be right on top of the video card's fan, it would suck out some of the hot air that the video card's fan blows away so that it doesn't just recycle the same hot air again.

    I have never seen one, it would be a good idea though.

    Do to the ATX standard, all video cards (that I know of at least) have their heatsinks and fans underneath the card. many cases do not have good airflow under the video card, which creates a "hotspot" where the heat produced by the GPU is just recycled constantly. The bottom of the case is also where most HDDs are located, which are another source of heat. If you have open PCI slots, you can remove the plate covers and cable tie an 80mm fan to it, this could help out alot if you have the space. just another idea.

    Yup, you and me are in the same boat :grinthumb Oh wait a minute that's a bad thing :( I'd say anything from a 400w from antec or the like will sort you out ok. You'll have no problems 'cause you can use that newegg shop you lucky American you. But here's a list of bad psu makers http://hardforum.com/showthread.php?t=792566
    so don't get any of those.

    that's a great link on good and bad power supplies there paranoid guy...

    That site will be handy for future PSU questions :)

    I can't take credit for that, I stole it from one of vnf4ultra's posts :angel:

    I got this crazy idea. Get a better psu to power my pc better but instead of going threw all th hassle of having to take out my old psu ( I have a sony case) unplug it and plug the new one into the mobo but leave the psu outside of the case. My case is already open. Wouldn't that lower the overall heat of the case? Having the psu out of their? And better airflow if I take the other one out. Any flaws in this ?( oh yeah and another thing will higher end mobos next year still support 20 pin connectors?)

    No. The case is supposed to provide airflow around needed areas. If this airflow is not there, its not going to help. The fans on the PSU suck hot air from the case and brings it out, at the same time cooling the PSU. So having the PSU out doesn't help.

    if your case is already open, then it shouldn't matter either way, it will just look kind of silly, haha :D

    probably not, but any good PSU you buy now will have a 24 pin connector with a 20 pin adapter or it will have the last 4 pins removeable. adapters are available to convert it either way as well

    I think that might be the source of your problem, try getting more case fans, and close the case up tight :D

    I hardly have any room for any lol. I don't know wether I should buy a PSU yet. I have a damn a propriety psu that has a 3 pin connector for the fan. Are their ways around this. My uncle also has a sony. His psu just died and he told me that we have to get the psu's sony gives us and he's really mad about it. Besides having very small room in the case for a diffrent psu theres custom psu's require us that we can only get new ones from sony if we want the fan to work.

    you can always modify the fan connectors, although that'll require some basic wiring skills....

    Yeah, he lives across the ocean and he's making a big deal about it. Why is it connected to the mobo to power the PSU fan or the mobo fan? He told me he'd try to look for a psu to buy him before I fly over their and because of sonys small psu's will have to leave it outside. Do most psus have a 3 pin connector to most mobos. Or is this another diffrence in sony psunits.

    Most mobos have 3pin connectors for fans. However, 3pin input to mobos is just about unheard of I guess. But all you need to do is to change the plug, and make sure you got the right voltages in the right points. Not very hard IMO, but I've done stuff like this before. Just need to get hold of your m/b layout.
