Hey guys so I am quite pissed off at this point. My Sapphire 6870 w/ Dual fans (DiRT 3 edition), might I stress again that it is has dual fans, is overheating. Now I've already posted many threads on this forum asking of how to troubleshoot this problem, yet I had no luck with any of the suggestions I was given. I pushed my OC back to stock (I was barely able to get any higher of a stable OC anyways), I even replaced the thermal paste with Arctic Silver 5, two times because I thought I might have added too much the first time. My temps when running Furmark or OCCT are easily 82*C + and this is at a stock overclock of 900mhz core and 1050mhz memory clock. When I play Just Cause 2, my temps are around 65*C - 70*C which are generally low compared to my stability testing temps yet they are still pretty high considering that the GPU is dual fan and the game isn't even that graphic intensive as opposed to BF3 or any of the latest games. When I play Witcher 2 however, my temps are between 70*C and 75*C. Now obviously this is not even close to normal as other people are getting between 50*C -70*C max even when stress testing. When my card idles it is at 33*C as soon as the system boots up. After about 10-20 min of idling it is at 37*C-45*C. Now I pretty much gave up on the card and I'd like to RMA it A.S.A.P.
My system is well cooled I'd say. I have a HAF 912 case that has two CM sickleflow 120mm fans as front intake. One stock 120mm side case fan that blows directly at my GPU, a 200mm megaflow as exhaust on the top and a stock 120mm rear case fan as exhaust. I even thought that maybe my airflow pressures were too neutral, or maybe there might have been a vortex that was disturbing the airflow so I turned off all my case fans except for my rear 120mm fan. This didn't change anything much so I turned on my side case fan along with my rear fan which also didn't help. After playing around with which fans were on or off I realized that the fans had nothing to do with the problem and that it was only the GPU that was full of crap. I'm getting sufficient power since I have an iCAN 600W PSU that should be more than enough even for two GPUs. So in conclusion, I am wondering if I can still get a RMA done even though I changed the thermal paste. The thing is that the way it was applied by Sapphire was using a perfectly rectangular applicator that had a shape a lot bigger than the actual TIM. So when I applied it I only obviously put the thermal paste on the TIM itself. If they open the GPU it's obviously going to be noticeable. I had previously already filled out the RMA form regarding a different problem. What I thought was that my GPU was rattling when at a fan speed of around 65%-80% but I think the problem was actually that one of those PCI-e metal slot cap things that block empty PCI-e slots from being open from the back of the PC case ( lol sorry I forgot the actual term,) was actually touching the metal around the cap that was on the input interface metal cap thingy of the GPU itself. This caused some sort of resonance that created the rattling noise at certain fan speeds. I think I fixed this problem myself but the temperatures are still killing me.
Sorry it is a long post but I gave up and really need to know if I can replace this faulty card. Thank you!

Also, when I play games using V-Sync my fps drops like crazy. Do you know why?
What I mean is that when I turn on V-Sync the average fps I have is much, much lower than normal. For example if I'm playing a game and the fps ranges from 35-70 fps, I turn on V-Sync so I don't get screen tearing from the excessive fps ( my monitor is 60hz) What I expect is that the max now becomes 60 fps and the minimum is around the same, yet instead the range of fps becomes 15-45 fps .
