You should try to find some way to get it down. Just for testing purposes,
open up your case and setup a big box fan to blow tons of air in there.
That should get the temperature down. I don't think it should be that high
for typical operation. Though I only have a 4 tuner...perhaps it's typical
for the 6 tuner to run much hotter. I'd be suspicious of that though.

I do remember at one point there was a driver issue that was causing it to
run hot in some 64-bit systems, but that was several years ago. Since
you've got a 6 tuner model, I presume you've also installed recent drivers
where that's been fixed, but it's worth checking (ex: if you had a 4 tuner
model before running with the old drivers, and then upgraded to the 6 tuner
model without upgrading drivers).

It's worth emailing ceton about it too. They might know something. Could be
defective hardware. My first Ceton card (3+ years ago) had an issue where
occasionally a tuning attempt would fail. It would start the channel change
process but then timeout and give up. If you told it to do it again, it
would tune successfully. Other than those small occasional glitches, the
card was otherwise 100% functional. After much debugging, on a whim Ceton
sent me a replacement card and the problem was gone.
