NVIDIA Has had Major Issues with the Build Quality for the 280 GTX that have Affected Operating Temperature, and has created High Failure/RMA Rates.
This is Failure Mode caused by one of Three Things:
1,) Lack of Parallelism, between the GPU Die, and the Cooler Assembly. (This would be caused by Poor Quality Components)
2,) Loose Screws, that Join the PCB to the Cooler. (This would be caused by poor Process Control in MFG. Process, IE: Fastener Torque Values)
3,) Potential Power Regulation Issue That Is Indicated in posts where Power Consumption went from 350 Watts to 550 Watts. (Thanks Keys !) Excellent observation.
