Max. operating temp. for AIW 9700 Pro???

Anyone know the maximum operating temp. for the AIW 9700 Pro chip?

I have this card and lately its been operating at around 166 F.....which seems a
little hotter than usual. This is during normal operation with WinXP and
non-gaming applications. It used to run around high 150's F.

I am thinking the fan bearings are starting to go bad and its slowing the RPMs,
and thus the higher temps. I think this card has a built-in thermal protection
whereby it shuts down when it reaches a critical temp, but I'd still like to
know it's operating temp. range. I checked all the documentation and the ATI
website but they dont have any specs on it.

Thanks for the help......

Whats that in real money? Rest of the world moved to decimalisation.
Still from what I remember about the conversion, its not a massive
change.

As a general rule silicon doesn't like working above 65-70C and it gets
critical at 80C.

I tapped on the heatsink fan a few times and it appears the fan started spinning
faster and the temp. fell to 56 C. I think the bearings are getting clogged
with dust and this is slowing the RPMs considerably. Not unusual since this
card is 2 yrs old and I dont routinely blow dust out of my case.

Anyone else have a fan die because of excess dust buildup?

Interesting facts.....but why would my fan be working well now if it had bad
bearings? I would assume it wouldnt spin at normal RPMs if it had bad bearings,
but it does seem to be working fine now.

Sometimes if you spin it up once by hand it will run for a while.
