I recieved my Sapphire HD3870x2 last week and it seemed to be working fine when playing games etc although I never gave it a good try out due to lack of time. I did notice though that unlike my 1900xt the fan always seemed to be idling when the games were running (it does start of fast when the computer posts). After playing today it is locking up my pc and then the computer crashes to a black screen, as that happens the fan speeds right up and its blasting really hot air out of the grill at the back. Ive taken the side of the case off and the white label on the heatsink cover has lifted off at both ends due to the heat of the card.

Anyone got any suggestions as to what to do? Im thinking that the card is borked and needs to be RMAd.

Also what program are you guys using to read you cards temps?
 
Got my temps with Rivatuner in the end. With the side of my case off it seems to be idling at 70 degrees and after starting the 3d model in ATI tool they went up to 82 and the fan started altering speed to keep it there. Im now thinking that maybe the case fan thats blowing onto the side of the card is keeping the temp sensor cool on when the GPUs are actually getting hot. Going to run some games with the side off and see what happens.
 
Seem to have sorted it now. It was a driver issue after reinstalling the 8.3s its working normally. Well an hours worth of BF2142 anyway, that got it up to 82degrees and it stayed there.

I am suprised how hot it is though its uncomfortable touching the black metal heatsink bracket.
 
Just a bit of an update. Ive reinstalled Windows XP and BF2142 and the problem is still there. If I turn AA off my system doesnt seem to crash even with everything on high. As soon as X2 AA is enabled though either in CCC and not the game or just in the game the system locks up and crashes.

Any more ideas? Im going to disconnect my second harddrive tomorrow and the cd writer to see if its a power supply problem. Although I would think the Enermax Liberty 620w should be enough.
 
Right the card is going back as it just takes longer to crash without AA on.

On a side note with the system in my sig when running 3dmark06 at 1680x1050 with no AA and the CCC 3d slider set to performance the mark im getting is around 9800-9900 would that be what you would expect or a little low?
