Yeah I had a feeling. And I agree with you completely. Question is how can I cool my gpu? I can't remove the heat sink or fan (warranty would be voided). Maybe upgrading my case? I don't know how to go about doing this properly. Or maybe I should just stop overclocking in general.
??? As far as I know, replacing the stock cooling solution on a graphics card does not void the warranty, BIOS Flashing it does.
You keep all the stock parts in case you do have a failure requiring an RMA, but how could they possibly know you changed the cooling solution anyway?
