Well, I'm still not clear what it is that you want.
If you want a high-performance card, it's going to put out heat.
Only way to avoid that is to go with lower performance.
There are lots of cards available with only passive heatsinks.
You can pretty much judge the heat output by the size of the heatsink.
Of course, the latest generation lower-end cards can have a better performance/heat ratio than older cards. But it's always a moving target.
