Also I find my D200's running temperatures are very dependent on what features are set - for instance I found recently running SAM can make it 8C hotter. DPM is very efficient at thermally managing the unit too. With DPM on I find temperatures typically around 40C max (usually the power supply slightly hotter than the rest) and generally a bit cooler than that. With DPM off the temp will increase to perhaps 50-52C with the A amp being the hotterst component.
I've always felt there was sound quality deterioration as the unit gets hotter (I've never felt it sounded worse cooler, contrary to virtually everyone else's opinion I've read). There does seem to be a point at the upper end of the temp scale where it just seems to dip in sound quality. I've been monitoring this quite closely recently as I've feared there could be a fault with my Devialet when it gets hotter, but so far it's playing ball.

Rufus, your temperature readings are pretty much the same as I experience with my 200 - 8 degrees or so hotter with SAM on whilst DPM reduces running temps by approx 10 degrees.  I haven't noticed any decrease in SQ with temperature but have been running with DPM on so the temp isn't running much above 40 anyway.

As an aside, although I really, really appreciate the additional bass extension that SAM brings I sometimes feel the music is being limited dynamically - perhaps by SAM, perhaps by DPM? (FW8.1.3, DPM) compared to 7.1.3 with no SAM and no DPM and may well revert to that earlier version.  Or perhaps I need to upgrade to a 400 and use brute force
