just ran 3dmark, walked off to talk to rents RE bulldog, line may or now might not be dying today, who knows
anyway, walked back in right at the end, it was louder but nothing dreadful at all. instantly 3dmark stopped fan went back to default/silent, only a 10780 score with 3.4Ghz conroe(i think i just downclocked it a little, couple crashes since i put it back to 3.6Ghz), but default options in drivers and stuff. not great, not bad at all though. gonna try ati tool and see if fan control works, though guessing not it might do, you never know.
overdrive i think doesn't appear at all without the 8pin pci-e , or i assume so as i canne see it anywhere
using the new downloaded drivers, not the 8.36's on cd.
so far with every generation of gfx cards yet fan at 100% speed is overly noisy and only makes 1-2C difference compared to a hugely quieter 70-80% speed. considering the noise at well, whatever level it was at, and the gpu tool monitoring and saying it only hit 71c under full load i would think theres deffo some leway there for adjusting fan speed a little for quietness and still fine operating temps.
that thing on , was it guru3d about "the fan kicked back in at 100% when it hit 100C", they turned the fan to the very lowest setting, which is basically no airflow, and it can't cool passively at all due to being shrouded. it was freaking irresponsible to post that as, i've done the same with the 8800gtx, well i put the fan speed down to 25-30% or whatever for the ultimate quiet and the temps started to steadily increase, i think stock the cards are similar, load temps so far are higher on the 8800gtx(though the fan here is slightly louder, but again also because i slowed the gtx fan down a little aswell).
its just stupid to post info like that in a review because they are trying to say its loud, because they essentially tried to cool a covered heatsink passively for a while and it failed, the fan is next to silent in windows and i would guess this will be the standard 40-50% fan speed, gtx's also heat up if you turn the fan to minimum, neither are designed to be run like that, but to point out specifically that the 2900xt overheats without any cooling. its overly attacking the card for no reason.
