A couple nights ago I was pushing my rx-v2300 pretty hard for awhile and the cooling fan never came on, I mean it got so hot I could smell it the next morning. Never shut down either. This fan worked at first I`m sure. What should my dealer do for this, I mean if they just get the fan working again haven`t I already hurt this thing getting it this hot? I bought it only 3-4 months ago. Thanks.
