try to reseat the cooler...or get a nice Accelero S1 like me
water isn`t needed, it`s just too expensive...even the world record is done with air cooling
Yep..reseated it..and its still insanely hot...68 idle. Strange thing..the VF900 is a good cooler. When i toutch the heatpipes they are very hot, so it doesent seem like a contackt issue.

weird
my Accelero`s heatpipes and fins are warm...but not hot or something...
i`d almost say the Zalmann Fan isn`t up for the job

is the fan even going 100% or is it stuck on 20% or something

youre just pushing around hot air in your case, the referance cooler with back exhaust
is really best suited for these cards, I have had zerotherm ones and regular ones and now my favorite the x turbo III version that comes on "some" of the rev 1 OC editions.

this is interesting, i'll v-mod whenever the duorb ax's come out (just feel like i'm jipping myself if i get regular duorbs now)

My v-tek does 885, diamond 870 on stock cooling (100% fans). i tried the bios mod for voltages on my v-tek but it ran too hot, so i kicked them back down. the fact that it made a significant difference makes me thing the bios voltmod will be enough for the clocks i'm looking for (950ish)

once i get the cooling of course.

There is no sutch thing as a bios vmod with the 3870. Doesent work. Simply only way you are getting the voltage any higher on these are by hard mod (soldering or pencil).
