Thank You for all the info, lol I didnt know it was a 25W fan, lol thats quite a lot I think compared with the older 19x00 series.
I currently have an x850xt and use the ati tool and I can hear the fan already at its 23% mark, and above that it gets quite audiable, not to mentione that at 100% its just unbearable, as if I had a hairdryiner in my case.
So Your advice is not to use the ATI Tool? ( I will definitively not be overclocking the card), since I am currently using a 1280x1024 max rez lcd monitor(for now) I usually used it because I never wanted for my current card to overheat, but i guess it actually reduces the fans lifetime, since it runs on higher speeds than it was originally planned, but with teh x850xt it was running on only 5% all time at stock settings till it reachec 70C or so. but i guess teh 850 cant compare tothe 2900 in its hsf, since the 8500 had not a gully aluminum build, only the fins, and part of the area which came in contact with the chip itselfe.
btw i looked at the card (back view) and i noticed that there is not much "cooling" material there, i mean only 1 black plate, is it a copper plate as well? I had some spare thermaltake copper heatsinks, and I was thinking aboutputing them also on top of that black plate, so that hopefully will reduce a bit teh temps of the memory, since i have 2 fans on the side of teh case which would blow some air on the heatsinks.
btw i thought the 2900xt had only 2 heat pipes, by looking at the photos of it.
Do you have any links to the dx10.1 articles by any chance? i read some (1) that said ati will be ok with 10.1 but nvidia wont, and teh rest of the articles mainly state that all of the current cads wil not support dx10.1, so i got a bit worried about this, and future lets say dx10.2 reelases.
