Gigabyte Designs Silent Radeon HD 4770, GeForce 9800 GT
Gigabyte has designed one of the first custom PCB designs for the Radeon HD 4770, this time, brandishing a silent cooler and double the amount of memory. The company also designed a new GeForce 9800 GT accelerator with a similar design and feature set. To begin with, the Radeon HD 4770 model GV-R477SL-1GI, sports a blue custom-PCB, which is built using the company's Ultra Durable VGA construction. A somewhat large passive cooler spans beyond the length of the card, and consists of three copper heat-pipes conveying heat to an aluminum fin block. The card features 1 GB of 128-bit GDDR5 memory. The GeForce 9800 GT model N98TSL-1GI(289) features a similar cooler over a blue custom UDV PCB. It makes use of 1 GB of 256-bit GDDR3 memory.

nice btw
wondering how much more expensive these will be though.... cause the 4870 1gb is dropping in price
I don't like 10.5"
ZALMAN CNPS9700
ZALMAN ZM-750HP
ZALMAN ZM-F1
and ZALMAN MFC2 to regulate all of the fans.
Great products. Great Cooling. Almost completely silent.
About a year ago, I bought a Gigabyte custom-PCB 8800GT and strapped a passive Accelero S1 (v2) to it. GPU runs at 39-44C idle, depending on the temperature of the room it's located in, and the hottest I've seen it get during gaming was 65C. Both GPU/shaders and memory are overclocked too.
Hopefully these cards don't suffer from electrical coil buzzing when the frame rate is high. With my Gigabyte custom-PCB 8800GT I only notice it when very close to the computer case and in very quiet ambient conditions (but the point of buying a passively cooled card is to attain as-quiet-as-possible computing, so it should be a design concern with these new cards).
They all make a distinct hissing noise, probably from their bearings.
