Ths CPU heatsink is fine, I checked that two days ago.
I don't do transcoding, commercial flagging or anything like
that. I just record some shows and watch some live tv from time to
time (my MythTV system is the only DVB-S tuner in my house).

The highest load for this machine is watching some 720p movies. And it
works good all the time - no crashes, no problems.

I did that when I cleaned the system (meaning it was 2 days ago).
Nothing changed...

I also think so. But the machine is on a UPS, just in case... :)
