    Graphics card cooling fans

    The fan on my graphics card has started to make nasty dying noises. Has anyone had experience replacing the fan on video cards? Any recommendations? Everything on the net seems to be total overkill, but I was considering some of the Thermaltake coolers or the Zalman coolers. (I have an Nvidia GeForce 6800.)

    Both coolers are good and generally quieter than the factor unit. Make sure you get the right one and be careful re: static when installing.
    Zalman VFU700-Cu is ok.

    The trouble with graphics card coolers is tha the damn things often cost more than your card is worth. Before you buy a cooler, double check what card you have and whether it would make more sense to just replacde the whole thing, prefferably with a passive-cooled card. Or, if it seems to be running nice and cool anyway, consider just removing the fan and taking a chance. If you have a cool-running card and your case is well ventillated and you don't thrash the system running stupid games, you can often get years of life out of the graphics card. (How do you know it's running cool? Touch it. If it's too hot to touch, it's too hot. If you can put your finger firmly on the chip and leave it there without discomfort, it's fine.)

    Depends what you really do with the card. I certainly wouldn't recommend no HSF on the card though, the 6800 series run pretty darn hot. With a stock HSF I'd expect at least 50-60 idle and up to 80 degrees under load easily, that's too hot to touch, and too hot to even consider running without a HSF!

    If you do use it for gaming, I'd personally consider an upgrade at this point. Plenty of good, cheapish cards around these days. If it's not used for gaming, I'd get a new HSF for it, especially if it's a 68800GT or Ultra, they're not bad cards still IMO. The Zalman already mentioned would do the job just fine, temps would probably drop in the region of 5-8 degrees when it's under load too. Cost around the $35-40 mark.

    I have a Zalman VF-900 on one of my 8800GTs here, it's a pretty big unit though and is a bit of a squeeze to fit in with the other vid card I have in here. Cooling wise though, it's up to about 9 degrees cooler when both cards are under load.

    Sorry, I didn't see that it ws a 6800. As Darksome says, they are a bit too hot to get away without a fan. Some of the older cards are fine, but that would be pushing your luck.

    Also check out how much for a new card altogether - perhaps you can justify "more power"? ;-)

    I always took fans failing as a reminder to replace the parts that were working hard.

    I have a high opinion of Zalman fans, they've been known to cure a lot of graphic card overheating issues over a long period of time.

    that is a pretty bad video card, heck I've got a 7300 GS 512mb just sitting in my wardrobe, I'm currently running a BFG 8800GT OC 512mb it was $230 brand new, and out performs the 9800 series ahaha, if your after a good/decent card.

    this is from Umart right now, best budget card on the market I'd say
    Gigabyte ATI HD4850 1G PCI-E2.0 GDDR3 HDMI HDCP Fan Internet Price: $296.00

    that thing will last you 5-6years + if you take good care of it!

    Thanks for your comments - I have committed to a Zalman VF-900. (I have the space in the case.) I can't justify a new card - the fan is still cheaper. I don't do gaming - the biggest loads are photo stuff, google earth and the occasional graphics program - and spare cash will go on something photographic .

    The old fan is dying due to dust: when it stops its horrid whiny bearing noise, the GPU temp spikes over 80C; unfortunately, the whiny noise when it is running is unbearable

    Oh, and I haven't time to research a new card.
