[mythtv-users] PVR-250 is hot! hot! hot!

[Robert Denier]

IMO your pushing things too much for the long term health of your
system.  I suggest picking up a quiet fan from directron.com or
something like that and adding one.

You could possibly run it on +12 - +5 = 7V from the power supply by
going between the 12 and 5 volt leads to keep it quieter.

I'd also be curious about your hdd temperature.  Bake a hard drive for a
few months and it tends to hurry the RMA requirement..

Still you may be perfectly ok, it just seems chancy to me with a poor
ventillation case, with both the fast GPU and PVR card in the long term.

64C isn't really ideal for the CPU either.  A very good heat sink with
some proper thermal transfer compound may helpa little there..


Good luck.
