  1. I recently underclocked my video card because of the wierd red low fps fraps was showing on max payne 2. It would lag occasionaly then jump back up to 50-60 fps. I then alt tab and check the temp when it lags me again. I see 79* celcius (it probaly dropped some so it plays at around 80-83*, oh and my vid card is a recent 6800 gs ddr3) . My gpu is now at 357 mhz from 350 and it still idles at 65 66 celcius with a fan on a stand at low close to it and 3 fans in the case. I guess I need some sort of real cooling product but I don't kno what to get. I want something that will last me so I'll be able to use it on my feature video card. OH ALSO I ran this crazy program rthdribl. Google it. It is this test and it puts any video card to its knees. I tried it out and my temps were like 86
    degrees. Does this look like a good buy? http://www.arctic-cooling.com/vga2.php?idx=40 or Should I go with cooling paste to fix this problem? (i dunno what its called)And the price is kinda hefty. Anyway its really bad when a gpu like mine idles at like 63 * these days when I read on google people get like 56 * under load which is crazy with thermal paste. This looks like a great deal http://www.newegg.com/Product/Product.asp?Item=N82E16835100007 . Should I go for that? Can it be as effective as the 33 dollar fan? I would buy a heatsink but Im afraid installing it will be too much of a difficulty. Any suggestions?

    when Fraps shows red fps, it means it recording the gameplay, and thats possibly why you get low fps. normal fraps fps are shown in yellow.

    check your fraps settings, especially the keys you use to show the fps, and look in the fraps program folder. if fraps is recording, it saves it by default in its program folder.

    see if that helps lower the temps. btw, the 6800 is a powerful card, that could also be a reason for the high temps. i have a 6600gt, and it idles as 50c.

    I understand what your saying about fraps but no how to lower my temp by doing it. Also it records the fps non stop not hot key needed. I want to buy cooling to lower the temps of my card so I can overclock it and play games without it topping 70 * . I just don't know if 5.00 dollar arctic silver paste will do the trick.

    arctic silver will do a good job of cooling.

    Before you do anything, check to see if your video card's heat sink is clogged with dust. I recently had a similar problem and it was caused by dust build-up. Those closed in heatsinks on the newer cards get clogged much easier than the older ones did.

    What should GPU temps be btw? I have a geforce 6600 256mb ram and it idles at 62 degrees celcius???

    Start you own thread so others can see it.


    It's high if that's a bit high though for ideling.

    I used it on my X800XT, and I managed to get it overclocked almost 20% without even reaching the usual temps pre-overclocking.

    Seriously recommend it if you've got good case ventilation. I found out that if your case ventilation is bad, you're better off with the Arctic Silencer. Bear in mind you probably want to keep the next 2 PCI slots empty too. Once all that done, this mean fan performs better than a Silencer.

    Is the artic silencer just another fan? Only slot I have open is the most bottom one but it has a small black box looking thing covering the first part of it. Wierd. I think I= have alot of room to apply artic silver paste on the bottom f my card is my heat sink and on the top theres a small black 4 sided flat piece nailed on to it. I guess this collects heat also. If I get the fan crossfire where do I connect it to the 4 pin connector coming from my psu. Since i'v been saving all my money earned for so far for next year when the new systems come out can this fan be used for future use? Probaly yes right? Thanks for the help I'll probaly get the fan and the 5 dollar artic silver paste.

    Edit: does the fan come with cooling paste? Which lowers card load temps more fans or cooling paste?
    I guess I have a medium sized case its large but not alot of room inside of it. Where would this card go exactly. My motherboards heat sink are little rectangular things sticking out and their right above my video card and its metal plate on the top. So if the fan attaches to the metal plate

    I'm not very sure which fan you're thinking of putting on your card there.

    If you don't have spare slots on the casing/mobo, I wouldn't suggest the Zalman, cos the hot air will just pool around the fan. Instead, go with the Arctic Silencer (AS) cos the AS will vent the hot air out. Bear in mind that the AS will take up an extra slot as well, and you probably can't transfer the AS from one card to another (unless you're getting an exact card, which defeats the purpose of an upgrade). The AS is designed specifically for one GPU, which is why there's so many versions of AS.

    On the thermal paste issue, the fans will cool the card down alot, and the thermal paste will help with this cooling. Fans, if used properly, will cool the card down as much as 20-25C cooler than stock cooling, while the correct thermal paste will reduce temps by a furthur 5-8C. I know I've enjoyed a total of about 30C cooler GPU from a VF700-Cu + Arctic Silver 5 (AS5) combo, but I had a good case ventilation and space.

    If you've read this forums alot, you'd find that we at techspot swear by AS5. And we're not the only ones around which do this.

    p.s. Thermal pastes can be used on any thermal conducting surface, GPU, CPU, NB, SB, Ramsinks, other electronics, etc.

    edit: AS5 is electrically conductive, make sure you follow the application instructions to the detail. Getting some on electical points can permanently damage your system. Make sure they stay clear of capasitors.

    thing is I have no room for this fan. My card is the 3rd slot the highest one and all the slots are taken until the very last one at the bottom. Any my mobo heat sink is right above my 6800 gs and above that is a fan thats like 4 inches wide (the case + fan) maybe not 4 maybe like 2 and 3/4 inches . Are there any small powerful zalmans? The card that was suggested looks too big to fit my card. I guess my best bet is getting some arctic silver 5 cooling paste. Yes?

    It'll help a little.

    Or you can always venture into liquid cooling.

    Also, you can always move the cards down to make space for an Arctic Silencer. Make sure you select the correct one.

    It should fit if it says its for the 6800GS. or 6xxx, or something like that.

    Anyway, the Arctic Silencer NV5 Rev 3 seem to fit all 6800 cards, but doesn't specify the GS. you can check out the specs tho: http://www.pccasegear.com/prod2928.htm

    thing i dunno if it will fit in my case, Theres a mobo heat sink right above my agp card and then a fan above that. So how big is this thing?

    Did you check the heatsink for dust yet? I'm 85% sure that's your HEAT problem but i'm not so sure the FPS dips are from heat even though 80+ is high. The fps dips you're talking about sound like a program running in the background like an antivirus program or kazaa or something.

    Go to the "Run" box in the start menu and put in msconfig. Click on the last tab and that will tell you what is loading every time windows starts.

    nah the heat sink is totally dust free. my start up programs are these and I usually close the ones that I see in my start up taskbar when they pop up. I want to get a really good cooling fan I have 60 dollars to spend but t seems that any fan I buy it won't make a diffrence none of them will fit in my case. I wish I could take a picture but my digital camera is acting up. Heres a picture of my graphics card. http://www.amazon.com/gp/product/B000EB9UUQ/102-3327940-0143323?v=glance&n=172282 . On the back theres a small plastic plate. Its facing towards the sky though not downwards. Is that where the fan attaches to. If so it has to be a skinny fan or it will scrape up against my heat sink which sticks out of my mobo like this. Don't laugh please. http://artpad.art.com/gallery/?j025unlrwdc . So yeah where should the fan go. The image is looking at it from a upper-side perspective with a transparent case...

    i haven't tried it myself, but you might want to consider this

    a stand alone all in one water cooler for your video card! can be mounted inside or outside of the case?? all for only $40!!! how cool is that :D

    I don't have an overheating video card, but if I did, I would go with this baby, you cant beat the price for what it does.

    Ok, lets take a step back for a second. I'm getting a little confused here about how much you understand about your video card.

    A) Your card already has a very big heatsink and fan and that should be all it needs to keep it cool.

    B) The heatinks/fans you're looking at are improvements but they replace the original heatsink. You'd have to take the original off and put the new one in it's place.

    C) Arctic Silver isn't "cooling paste", it's a thermal paste and the ONLY thing it does is help heat transfer from the chip to the heatsink there fore allowing your heatsink to work better. It does nothing on it's own.


    So the bottom line here is simply that something is keeping your stock heatsink/fan from working properly and 99.9% of the time it's one of the following two things.

    1) Your card's fan is either dead or not getting enough power to work right. Do you have the card plugged into a 4-pin connector from your power supply?

    2) Your giant cavernous heatsink has dust in it's tubes. You have to take the card out and either blow really hard through those tubes or blow some compressed air in there.

    Caxus, I must say you've never replaced stock heatsinks and fans, have you? There is a huge difference in temps from a stock cooler and an aftermarket one.

    Arctic Silver may not be cooling paste, but it will help reduce the temps on the card anyhow. But maybe we should still stress the fact that you'll need to use it with a heatsink and fan combo.

    If you're going to venture into watercooling, better a whole setup, no point watercooling one component, and not watercooling the rest.

    Bear in mind you should only consider watercooling the GPU and CPU, forget the rest, its more or less pointless. Video RAM shouldn't be watercooled neither according to the guys at www.extremeoverclocking.com, so you don't have to get a waterblock designed for a particular GPU.

    No, i understand that the aftermarket ones, are in many cases, much better. My point was that his temps are abnormal and he probably doesn't NEED to buy a new heatsink to fix the problem. If he had normal temps and wanted to get even cooler then that's one thing. But it doesn't sound like that's the case. In his case it would be like buying a new car just because he has a flat tire. Besides, a lot of his attention seemed to be focused on the back of the chip where the clip that holds the heatsink on is. I think he needs to be focusing on his current heatsink and fan before deciding if he wants to upgrade.

    About the arctic silver, it sounded like he was under the impression that it was something you spread on the chip to cool it and i just wanted to make sure that he understood that it was something that goes between the chip and the heatsink for better heat transfer.

    Caxus is write. I thought you smear it on the back plate on the card or something lol...Anyway it is impossible for me to tell wether my card fan is on or off. Damn you PNY. But I can see a small green light coming from the bottom of the card near the fan that is on. So I guess that means I plugged it into the 4 pin power correctly thats plugged into my psu. Also my card came with a Y shaped 4 pin connector. Maybe the card came with the Y shaped connector not for sli support but as another plug into the PSU? Do you guys follow that? Right now the card is like 64 degrees Idle. I live in florida and its very hot in my houe atm (88 Farenheit) with no A/C and my big fan isn't on. Im about to shut down my pc so I didn't see the need. It could very well be that my fan is not on. But on cooler days my card temp would be like 62-63 degrees. I read owners with the 6600 gt get liek 66 degrees idle I kno its hot but if there fans are which im assuming is true then I guess this is just the normal temp for my video card. un cool; I guess my card is just crappy temp wise.

    That could be your problem right there. It sounds like you DO have it plugged in correctly. Those splitters are just for if you're out of 4 pin connectors you can split off from one of your drives or something.

    I also just want to make absolutely sure that you've taken your card out of your computer and blown through the tubes in that heatsink.
