Measuring Power Draw

PowerColor's SCS3 HD6850: Radeon HD 6850 Goes Fanless
By , Greg Ryder

Interim Assessment and Important Note:

The power draw of this card is average compared to similar Radeon cards. However, we were not able to finish all power tests because the card went into thermal shutdown when we benchmarked it on an open test rig with two monitors attached. At that point, the power meter already displayed 142 W.

As useful as multi-monitor support may be, without a fan, one simply cannot stress this card to its limits. Therefore, we added an ultra-quiet fan for the rest of the tests. Additionally, we conducted them in both passive mode and with the auxiliary cooler. We’ll elaborate on that later.

    I you rev the nuts off the fan can you get a super over clock from the card?

    the fact remains, to use a silent graphics card at it's full potential, you need a noisy case!

    Tom's... I think you've forgotten that heatpipe towers are hugely reliant on static pressure and airflow... of course sticking it on an uncooled open testbench will result in fail...

    Ultimately true passive setups involving mid-TDP parts will always remain impractical or a gimmick, as they always need some sort of forced airflow across them to remain workable. Turning a Big Air system into a Quiet Air one through Arctic/Scythe/Noctua abuse is always the better idea.

    i had a fanless solution on my 88gt done by sparkle. it worked, just. i put a 60mm cpufan on it and wow. temps down to 40'c from near 100. the cooler itself was ok but was blinding when you gave it a push... i guess this 1 will do the same. add a couple of low noise 120's and i bet the temps tumble... then again i hoped they would come with a fanless solution because the build quality for there fans is poor... min didnt even last a year on my 5870... also there customer service is second to none... it has to be the worst i have ever encountered from a new-ish entrant into the market.
