If you think you have a heat problem, open the PC and run it until you
have your suspected heat issue. Then spray the suspected component with
freeze spray and view if you have any changes in the video output.
Sometimes you can find intermittent thermal problems with freeze spray
-- not always.
On the other hand, how many people have heat problems with PVRx50s? It
might be something else.
I don't know how many people, but I'll raise my hand here. In the past 2
years I've had 4 PVR-250 cards die due to heat. The 4th one just gave
out a couple weeks ago. First the tuner gets noisy for a month or so,
then I start getting dropout that results in corrupted recordings and
cause commercial detection to crash. Then I buy a replacement.
I'm currently down to 2 cards again and am planning this time to replace
with two PVR-500 cards.
My system is a RedHat9-based Athlon 2600+ in a Gigabyte GA7VT600 MB with
512MB RAM, watercooled in a 4U rack chassis. The PVR cards get HOT and
are the main source of heat inside the chassis. They seem to last up to
a year. Of the 6 total cards I've had, none of them are still in service
after over 2 years.
YMMV :)
