Sparkle 8800 GT Passive: The Fastest Silent GPU in the World

Once again, Crysis was our benchmark of choice as it seems to put the greatest stress on GPUs. We played for hours on end until the GPU temperature leveled off, using nTune to monitor temperature levels from the GPU's on-die thermal diode. Note that playing Crysis actually got these GPUs hotter than looping the 3DMark '06 HDR/SM3 tests, although only by 1 - 2C.
Interestingly enough, at idle, both the stock 8800 GT with its fan and the Sparkle passive card reach about 76C. The only explanation is that the 8800 GT's fan is designed to remain as quiet as possible, so it doesn't actually do all that much cooling when the GPU isn't being stressed.
Running Crysis, the stock 8800 GT's GPU peaks at around 94C with the two 80mm case fans in the system unplugged. The passively cooled Sparkle in the same situation is already at 111C, an increase of 17C, not nearly as much as we honestly expected but still quite hot.
Turning the case fans on drops the GPU temperature to 106C, showing that airflow in the chassis is important.
The impact on CPU temperature was actually marginal, the hottest of the four cores of the QX9770 only saw a 3C increase in core temperature.
Despite our best efforts, the Sparkle 8800 GT Passive prevailed, although posting some worryingly high GPU temperatures the card never crashed during our tests.

I agree with Cerb. The fact that it reached 111C and did not fail is a good sign. And that was recorded with the case fans off in a poorly ventilated case. I'm gonna get this for an Antec Solo which has a single 120mm case fan at the rear over the CPU. I'd expect a temp a little lower. As for such high temps affecting the life of the card, well it does come with a 12 month warranty. If it hasn't failed in that time running close to 24/7 then the chance of it failing soon after isn't going to be a great deal higher.natrap - Saturday, December 1, 2007 - link

Great article anand, LOVE the Sparkle thumbnail :Dgochichi - Friday, November 30, 2007 - link
A lack of HDMI for this type of card is simply unacceptable.I wish the heat pipes wrapped further down, and in general, fan-less cards such as these (the ones that perform) should come with the option of adding standard two 80mm or one 120mm fans. The heat sink needs to be more impressive.
I have (though I don't use it anymore) a fan-less X800, and while it was marginally fine for a while to use it fan-less, I used to lay a quiet 80mm on top of it... I wish I could have easily secured the fan.
You see, fan less cards are meant for the few, the people that want more options. The price could easily be $350.00 if the card was right, and it be THE card to own for the enthusiast. You could down clock the card and slap it into a poorly ventilated case, or you could slap two 80mm fans on it and overclock it more than any other.
That's my two cents. To me, this is no good... if you care about quietness, it would be better to buy a regular card that self-cools... b/c leaving it up to the case means multiplying the noise.

Next day shipping almost always costs $30-$50. I'm not sure why this is so notable?Bozo Galora - Friday, November 30, 2007 - link
Or, you could have run the card at 54 degrees under load by using the new Thermalright HR-03GT GPU HS with 92mm Fan.http://forums.vr-zone.com/showthread.php?t=208305">http://forums.vr-zone.com/showthread.php?t=208305
You still could even amend this article with same, or even do a new one in cases cooling. Then you would have both ends of the spectrum.
And, supposedly, according to one report on the web, the 8800GT was not a paper launch, but some components needed for the board were in short supply. "Nvidia declined to say which ones".

My point being, after looking at this review and testing of the Sparkle version of the 8800GT, it seems to me to be an added cost for less than adequate benefit. Perhaps you won't be using the card to play games like Crysis at full break to see how hot it can get and for those people this will probably be just fine. However for those that want silence and power wouldn't it be better to get a stock 8800GT, the cheapest you can find and then put on a Thermalright HR-03 Passive VGA cooler that is made for Nvidia 8800 cards. It achieves the same thing as Sparkle's design except it's made to better dissipate the heat. Granted it costs around $50 but it's also larger and more efficient. I think personally it's a safer and better alternative than the Sparkle design. Though kudos to Sparkle for at least attempting.scottb75 - Friday, November 30, 2007 - link
What kind of computer case (if any) was used for this test? Because my EVGA 8800GT SC at stock (SC) clocks and stock fan speeds runs about 57C idle and 78C at load. If you are getting 72C idle and 94C at load on a stock 8800GT something is wrong.stapuft - Friday, November 30, 2007 - link
Agreed, mine runs 52/72C on Crysis, fan at 35%. 56/78 stock.The story in Anand's blog about failing 8800GT's and 3870's would make sense if they had cooling problem. Pics of the test rig and ambient temperatures in the office at time of test are called for.
BTW, if you're in a hurry, you deserve a high price for shipping. Lose the rant about it. EVGA is a standup company.
