Gigabyte Silent Radeon HD 4850 in the Works
Gigabyte might well be the first AIB partner for ATI to release the first passively cooled Radeon HD 4850 accelerator, and a 1 GB one at that. The Gigabyte GV-R485MC-1GH sports the RV770 graphics processor clocked at 625 MHz and 1 GB of GDDR3 memory clocked at 1.00 GHz. Gigabyte is to use its "Multi-Core" passive cooler that consists of two arrays of aluminum fins, with two copper heatpipes each conveying heat from the core to the fin arrays. The card will feature Ultra Durable 2 high-grade electrical circuitry with what vaguely looks like a 4 + 2 phase power design. The GV-R485MC-1GH will be available soon. Word is that PowerColor would follow Gigabyte with their passively cooled Radeon HD 4850 model.

holy crap, one of the hottest gpus on the market passive cooled? that sound fool, but the most foolish plans sometimes work :D
Go gigabyte and Silent pipe 3. :respect:
on full load, never pass over º 55, and doesnt had any fan attached. :D
One thing that a buyer must remember is to keep the case closed in order to maintain the airflow... But a lot of users forget this...
I had a Gigabyte 7600GT passively cooled (Silent Pipe I) and used to love the silence, but my gpu temp reading was showing 70C idle if I remember correctly and my mobo was getting above 45C. Felt very uncomfortable with this solution, and I'm only a casual pc gamer, so I don't even want to think about the potential damage it can do to a hard core gamer's rig.
As said above, unless you have some outstanding ventilation in your case, there's no point in getting this card. And still, better case ventilation generally goes with higher noise (unless going for quite expensive solutions), so it defeats the whole purpose of the card, IMO.
I love the idea though, and really hope they'll pull it off this time.
I tried to use my 8800GTX passively with the HR03+ heatsink. It worked about 2 minutes. Windows started to get unresponsive, GPU temperature @ 115 C :D (at this point it was clear that the GPU was throttling to keep down the temperature). I could feel the heat emitted from the heatsink at 10 cm.
After that "incident" I no longer worry about GPU temperatures. And yes, my 8800GTX still works flawlessly.
And then a pci slot exhaust cooler under that.
I dunno, video cards running over 70c irritates me even if they are built for it... Really I would like to see everything in my machine stay under 50c.
but i agree lower is better :D hence why i'm all on water
