yep i have 2 of them and after cleaning and doing the thermal paste they run at 90*c. the heat sink is garbage.. i have a 140mm can just sitting ontop of them blowing air right into their heatsink to keep them at 90...

they are an extremely poor design. i just hope when they stop working xfx will give me 7770's with devent heatsinks...

ive been mining nonstop on mine for 2 weeks with no problems at 90*c just put another fan ontop of them.
