Re: EVGA GeForce GTX 260 C216 Superclocked or Vanilla GTX 275?
Well, it sounds like you don't have A/C either and/or your case might not be the most efficient at cooling. If you have the money, I'd invest in a case with a good cooling solution and I'd like for cases with very large fans. Cases with larger fans are better because the bigger the fan, the more air that is moved and they are bigger fans are quieter than the smaller ones.
I've got 5 80mm case fans and it cools pretty well, that said I'm also around A/C in the summer so I can't say for sure how well the fans cool in the heat but I know it takes the heat out pretty well.
