This card has been good to me until I messed with it. I decided to clean out my case and redo the wiring and put new thermal paste on the cpu (1090T) which lowered my idle temp by about 7-8 degree's (33c Idle). Since that worked out so well I thought I might as well do the same with my video card.

Temperature Increases rapidly once it hits 65c.

Before this I was using AS5 compound using the pea method/ light spread/ X method, but I ran out of AS5 and actually had worse results. I had some no name brand laying around and did the spread method again and those are my current results. I don't know if it needs time to cure or what, but I can't run any games or it starts to lag when it reached 105c (max safe temp for this GPU). I'm surprised it still runs at this temp and has yet to shutdown on me. What is actually weird is once it hits the 100c range it stays between 100c-107c no matter how long I run furmark for. Any ideas?
 
This is what I had to do to cool down my old GTX 280... :D

Been a couple years now and it's still chugging along! (in the HTPC these days)
 
I ran into the same issue when I was working on mine a few years back.

The most basic issue is AS5 performance falls off a cliff over 70c, I recommend IC Diamond 7.

The other issue is there were major irregularities on the bottom of the heatsink for alot of 280's, as a result they need a ton of thermal paste.
 
Hey Phas3Zer0, Did you notice anything wrong with the card before cleaning it? You probably just need to go back and re-check everything. Are the cooler mounting screws set with uniform torque?
