Radeon 5970 Overclocking: The VRM Temperature Bottleneck

[InCredible]

I have a 4870X2 and have modified the fan profiles to keep the GPU's and VRM's under 75c with 20c ambients. When ambient temperatures rise in the summer I use a different profile... its a little louder but keeps the card stable (I have had crashing issues at 85c+).

i have one as well and never had any issues from crashing when it hit into the 90c+ ...now i did modify the cooler and took the stock fan out added a 120mm on top of the card to lower temps and get it silent which helped a lot...one thing it messed up was the vrm cooling so i had an issue there..now im on water..but ive had 127c vrm's and 90c core temps and still playing benching ..not the best i know but it did it and never crashed or saw performance decreases while gaming..
now its much better since its watercooled and never seen anything over 80ish vrm unless under furmark and core max at 50c..but this change was just in the past month or so and ive had the card since launch.


EDIT. for the arguements between Bababooey and led....baba u make a good point all Ledhed's overclocking is on refresh cards and not on the first generation(compare 4870 to 4890 for instance)

now maybe nvidia is smarter for not using their first generation of a gpu to make a dual gpu card since i think all their gx2/gtx295 etc were a refresh of the previous gpu's....while ati does their dual gpu on the first generation of the gpu..however it still works at stock like its suppose to and yes it can overclock at 1000mhz..we've seen this multiple times..just might have to change some stuff to make this work 24/7 etc..

ati could of made better cooling and maybe will even come out with a better cooled refresh but right now you get the best card with coolin for stock clocks for the most part...atleast when ur playin furmark.
