Re: I solved GTX280 overheating issue
Also if it were an airflow issue, exchanging my card for another one would have had no impact. Instead not only did my replacement card run 20 degrees cooler, it didn't overheat and throttle (if the overheating cards didn't throttle they would go well beyond 105 degrees).
My defective card ran at 105 degrees with throttling.
My replacement card runs at 85 degrees no throttling and the same case.
