If I use my receiver as a pre-amp, will it run cooler than...

    it does as a full-fledged receiver? I have an Integra DTR 6.4 and since the temperature has dropped in my basement room (winter is almost here), I've noticed a noise (I've posted about a similar noise in the past, but I determined, after extensive trial and error, that it was related to video relay switches) coming from the receiver after it has warmed up. It does not run too hot (only moderately warm to the touch) but it appears to suffer from "popping" noises owing to expansion/contraction of the rather thin metal case and the plastic faceplate (perhaps from other internal components as well). I cannot, nor do I wish to, maintain a constant temperature in that room just to "baby" the receiver (too wasteful of electricity and money). If, when finances allow, I decide to add outboard amps (encased in material not prone to this "popping" noise--will seek suggestions when funds allow), will my receiver run noticeably cooler and diminish, if not eliminate, these noises? I am quite satisfied with the feature set of my receiver and I'm reasonably happy with its audio performance (though I've toyed with the idea of a separate two channel rig, that's really only in case of an unforeseen windfall--lucky night at the casino or some such thing, in other words, unlikely) and would like to keep the receiver until it is truly broken or obsolete. Adding outboard amplification at some unspecified future date was always part of the plan, but if that addition doesn't help solve this noise issue, then perhaps I'll go for another receiver (or wait longer and get separates).

    It most certainly will run cooler. The amps generate 90% of the heat.

    From personal experience, yes it will run cooler. I have a Yamaha HTR-5790 that was powering a set of 5 Ascend Acoustics speakers. I purchased two Outlaw monoblocks for the mains, and the temp of the receiver went down substantially.

    I've left it on continuously, as suggested by several people, for the past five days and the problem has greatly diminished (though not entirely disappeared). I'm happy this seems fixed (for good, I hope) but I'm disappointed to have to resort to such a procedure because of a flimsy casing.
