Bare with me because there are 2 elements to this issue. Green dot crash & one of the fans not working properly.My specs

My 9 month old XFX R7970 Double DIssipation GHZ Edition has been having issues the past 2 months and it's gotten to a critical point. At first it was an amazing card but 2 months ago I started noticing in certain games that at any given moment these green dot artifacts would start flashing on the screen all over. It would start out with a few dots and then if I stayed in that spot in the game it would get worse and worse until the dots filled the screen and the game crashed back to desktop. I get an error message stating either "the driver crashed and recovered" or something along the lines of "DXGI_Device_Removed"
The strange part is that the games perform extremely smooth and then the green dots appear and the game crashes while still running smooth. My temperatures are all normal with 30C idle and 70C full load and I'm using the stock clock settings. Even the VRM temps are normal. When I run the 1080p benchmark in FURMARK I can replicate the issue every time and it will crash with white rectangle artifacts appearing within the "donut" object.
Originally I thought maybe it was either the drivers or those 2-3 specific games causing the problem because other games would never crash. But now it happens in every single game that I play and it happens quicker than before. I tried different driver versions and even formatting my computer and starting over. Nothing solved the issue.
So then I thought it might of been my Corsair 800W power supply because if I went into CCC and lowered the Power Control to -15% I could get Furmark to complete a full 1080p benchmark without crashing. So I swapped it out with an XFX ProSeries 1250W Power Supply thinking my problems would be solved. Of course it did nothing.
THEN today I noticed that one of the R7970's fans (closest to the back of the case) wasn't even spinning. I tapped it with my finger and it started spinning but it's making a grinding/whining noise and is struggling to maintain the full RPMs. It just keeps slowing down every few seconds. So I'm guessing the fan is faulty now too. But it can't be just the fan causing these problems if the temperatures are still operating at a normal level, could it?
I'm thinking something internal was defective and over time it got worse and worse to the point where it started to effect that particular fan. I've tested my RAM with memtest and it's all good. Replaced the PSU and my motherboard is operating properly. So the only culprit left is that my GPU is defective. But I don't want to RMA it until I hear from someone here just in case it's a common issue.
Here are some screen shots of what the green dots look like in games before it crashes altogether. Any ideas?
