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.

Sparkle 8800 GT Passive GPU Temperature

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.

Sparkle 8800 GT Passive GPU Temperature

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.

Sparkle 8800 GT Passive CPU Temperature  

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.

    totally agree.

    Also the design of the sparkle doesn't look all that genius anyways.

    eg. what about if you mount a zalman VF1000 or thermalright HR03 and simply pull out/not mount a fan??

    how does it compare?
    the sparkle model here could have easily made mounts for a fan which would entice many more buyers like me. (fan attached to fan controller, run fan only when necessary)

    With zip ties and a bit of imagination fans can be attacted onto almost anything.

    As for the card, I suppose a non-passive plus Thermalright HR03GT and a low RPM fan would be the best solution for quiet but not entirely silent cooling.

    111 degrees is not ok IMO, heck not even 94 degrees.

    I don't post here often, but that Mr Sparkle pic gets my two thumbs up for this review!

    I'm sure you would have seen much lower temps with a different case. A perfect solution would be a box with positive pressure and vent(s) on the back, along the PCI slots. Some Antec and Silverstone towers, or most boxes with big fans on the front, would fit the bill nicely. Not many HTPC boxes are capable of positive pressure, but the way-too-pricey Silverstone CW02 has 2 90mm intakes and the PS draws from out side the box, allowing for positive pressure.

    The Velocity Micro case used in the review is actually the OriginAE X11. I don't think this box has the airflow desirable for a powerful passive vid card. I've had excellent results with using a Silverstone LC-20M and an XFX 7950GT HE9 (570 MHz). While positive pressure isn't possible with this box, I still get quite satifactory temps with a factory OC card. The PCI vent becomes an intake due to the draw of the 2 80mm rear fans and lousy intake from the front of the box. This results in a 10C drop, as compared to open case/no case running.

    One similarity between the OriginAE and Silverstone cases is the PS mounted on it's side, with the lid mounting directly on top of it. Was there much (any) clearance between the card and the lid? In my box, there isn't even 1 CH of space left.

    If possible, I ask you to put the card in a more suitable box and post the results. A P180 variant should be able to bring out the best in this card. With some tweaking, a very quiet SLI system should be possible.

    Thanks,
    Bill

    btw, i love the mr. sparkle picture. he is disrespectful to dirt!

    Totally agree; so awesome. I would not even have bothered to read the article, but that picture drew me in.

    Believe it or not, the 512mb 8800GT was meant to be 199->249$

    This is why Dell can do them for 208$.
    This is why Fry's / Outpost did them initially for 229$
    It's certainly not meant to have started at 249$.

    You'll find early Jan when the sales taper out, it'll be as low as 199$ US (best case, perhaps with rebates) and 229$ average.


    Damn good, especially considering the poor prices of the new GTS and how it performs :(
  • shabby - Thursday, November 29, 2007 - link

    No its not incorrect, the 199 pricetag was for the 256meg gt, 249 was for the 512. If you believe the 512meg gt was supposed to sell at $199 then why did ati price the slower 3870 at $230?
  • AbRASiON - Friday, November 30, 2007 - link

    I believe that, because that's what every damned review said 6 weeks ago.

    The 256 pricing was unknown at the time.
