How about a passively cooled HD7850

[Phynaz]

Wow, never thought I'd see this fast of a card running silent. Only 1GB of memory on it though.

There's surprisingly little surface area on that card, I've seen 7770's with larger heatsinks.

Powercolor = toaster oven. They use a red PCB to reflect how hot it will run in a case.

I'll believe it when I see some actual tests, until then I highly doubt it.

You can game for 10 mins at a time, before must cool down

Very interesting. I'd like to see temps.

Should've used a blue PCB instead. Blue will make it run cooler. :ninja:

This must be like my laptop, games just crash after 15 minutes.

I’ve had some experience with passively cooled cards and they’re completely viable, providing you have reasonable case airflow. Anyone buying high-end cards probably has a good enough case anyway.

I've never got "passively cooled" CPU's or GPU's
You still need case fans, and then you could just force the fan speeds to that noise level. :\
