I know this, when I touch it, if it's an uncomfortable warmth, it's too hot, I don't care if it was designed to be "ok" with running that warm or not. The cooler you run it, the longer it will last, period.
As a longtime PC builder and overclocker, I can tell you for sure that hot heatsinks are a good thing. Mine certainly gets warm, but so does my Denon, my D*TV HR-20, and quite frankly my router runs hotter than the MFW-15.
You guys are welcome to throw fans on them, but it seems like overkill to me.
As a PC builder since 1978, modder, you name it, I've built a lot of systems, servers, networks what have you and this is the very first time I have heard that hot heat sinks are a good thing. A heak sink is deisgned to pull heat from a device, not keep it there. A hot heat sink on a CPU is most cetainly not a good thing and inhibits overclocking. My system runs dual Quad cores and the heat sink is barely warm to the touch, the chipset heatsink is barely warm to the touch (well designed cooling at work), much better than running hot to the touch any day.
A hot router can be bad, a hot AVR can be bad (mine runs cool, again, effective cooling at work) but whats hot, 100f or 140f or 160f, for me I prefer to run my equipment as cool as possible, my computers I choose to run as cold as possible and have designed some interesting ways of doing it.
So, you continue to run that equipment hot/real warm what have you, my stuff will be running 20 years from now, depending on how warm/hot whatever you let your equipment run, won't.
