[mythtv-users] OT (?) heat/noise: underclocking vs. cpufreq

[Franco]

I hope this isn't too OT; however I recall
somebody recently wrote that the heat/noise issue
is interesting for most mythtv users.

I found http://www.silentpcreview.com/ an excellent source
of information on this regard. Among the other things, they
have a (partial) list of motherboards that easily allow
undervolting/underclocking (click on recommended ->
undervoltable motherboards).

Before I make my purchase based on this partial list,
do you know about other undervoltable/underclockable
motherboards, that are not in that list but are maybe
more suitable for a mythtv box?

I also have another big question: ;-)
did anybody try to play with the "cpufreq" module?
Does it work?  It would be very nice to be able to 
change the CPU frequency on the fly... one could
make a powerful/hot/noisy box for normal usage,
and then make it slow/cool/silent when he wants to 
listen music...

One could also fine-tune the best tradeoff between 
speed and noise, without having to buy a dozen
different processors for trial and error... ;-)
