hey ,
maybe some of you remember my last topic about modding a ATI Radeon 6950 to a 6970 ?
just FYI they are still running fine at crossfire with really awesome performance in combination with my 4 Ghz processor...
the only thing I didnt like was the temp behaviour and the noise level of these cards...
this will work for all of these graphic cards :
ATI Radeon 6970,6950,6870,5870, 5830, 4890, 4870, 4850, 4830, 3870, 3850
nVIDIA GeForce GTS 250, 9800GTX+, 9800GTX nVIDIA GeForce GTX 285, 280, 275, 260+, 260
nVIDIA GeForce GTX 465, 470
nVIDIA GeForce GTX 580, 570, 480
nVIDIA GeForce GTX 460, 560 Ti
important:
you will loose warranty if you are going to do this
this is not a cheap solution but it is really worth it....
just be sure your case is big enough because this is a really big cooler LOL
the cooler:
Arctic Cooling Accelero XTREME Plus

you also need some RAM heatsinks to cool some parts of the card
there are 5 different to order for the different cards
the stock coolers made a lot of noise under heavy load and the first card had almost 50°C/ second card 45°C on idle and almost 75°C/70°C at heavy load while gaming or benchmarking
though I have a really well vented case with 11 fans....if you have less fans temps might increase a lot more
some tests I read reported temps of 85°C+
after installing the new XTREME plus my temps are now at 36°C/29°C on idle and 50°C/45°C while gaming and benchmarking
both cards running fine at 950Mhz/1450Mhz maxed out without any issues
if you think about changing your gpu cooler have a look at this beauty
here are some pics of the install

exploded cards:
you have to install the heatsinks there
installed
have a nice day ))
