I've looked athe Arctic Cooling's website and it doesn't look like there is
any provision for cooling the RAM located on the backside (opposite the GPU)
of the PCB. Does the Arctic Cooling Silencer 5 rev. 2 only cool the
front-side BGA RAM?

I bought the one for my X850Pro and yes, it does have a backplate which
presses against the back ram. The plate has the same thermal tape for
the memory as the main heatsink.

You won't get the same airflow over the backside of the card, so
cooling provisions are limited, but the heat diffusion properties of
this plate should help.

This backplate is not shown on the main product page, but select the
'pictures' link, and scroll through. Best shot of the backplate is

|Not sure if it represents a cooling improvement over the stock heatspreader,
|but it does stiffen the card considerably.

I have one on my X850XTPE and the main benifit is how much more quiet it is over
the stock one. If my friend hadn't told me to expect the stock to be that loud,
I would have assumed it was broken.. at boot its MAJOR loud. With Arctic Cooler
on .. its super quiet now.

However.. if I where to do it over.. I'd get the Zalman cooler instead.

I'm talking about the backside RAM-sink that looks like a glorified cookie
tray. I don't think it performs any better than the stock heatspreader.

Does the X800 hardware monitoring give RAM temperatures?

This is not news. I have an X1900XT with a louder fan. :-) However, the
noise drops to inaudible levels within two seconds of POST, so it isn't an
issue.

If you have good case ventilation, sure. The Arctic Cooling unit exhausts
hot air out of the case; the Zalman doesn't.

Noise drops, yes - but then fires back up when the card is being
exercised. At least for me.

That noise from the fan when the card's being used taxed by a game is
why I switched to the AC. It hasn't made a whisper since.
 
For me, the noise occasionally fires up in an intense game, but never to
full speed. I play Oblivion, Quake 4, Wings of Honour, Quake II GM dynamic
shadow mod, etc.
