I have read in other postings that the Yamaha RX-V2500 tends to get very hot, and that it has an internal fan. Two questions: Does the RX-V2500 have any heat related issues/problems? Has the internal fan been an issue? Usually the first thing to fail in electronics is the fan. The reason I am asking is I'm trying to decide between the HTR 5890 and the RX-V2500. The 2500 seems to be very popular so any input on why to pick it over the 5890 is most welcome.
