Got an used version of this card 3months ago. The card is under warranty and all the documents are provided along with the card.

Initial idle temps- 35-38
Season - Winter with room temp 20-24
Max load temp (Furmark)- 70

Idle temps now- 40-45
Season - Summers with room temp 32-37
Max load temp (through Crysis 1 by GPUZ)- 75-80

1. Is it overheating? Does it need any dust cleaning, thermal paste changing, or any other PC housekeeping?

2. If it overheats I will replace it with RMA. I have no knowledge of RMA claiming. So I fear that as product is permanently discontinued they will replace any other lower card like 6750 or 6670 ddr5??? Its fine if its replaced with any of the 7series, but it seems quite unlikely.

Need suggestion, as I think I see some glitches during gameplay like floating grass in Crysis and late loading graphics in GTA 4. Thank you.
