Gigabyte Designs Silent Radeon HD 4770, GeForce 9800 GT

[btarunr]

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.

I like that 4770. I have never been a fan of passive heatsinks, but for my HTPC this would be really nice though.

awesome.

 

[werez]

i simply hate it ...

Finally! GIGABYTE Ultra Durable means quality parts like RDS MOSFETs, ferrite core choke and lower ESR solid capacitors. Combine this with 2x memory and you have a winner HD4770 with super cooling (have in mind that you can't mount Accelero S1 rev.2 on HD4770)

i've seen that yesterday ^^
nice btw

That cooler looks alot like my Accelero S2 (except with 1 less heatpipe). Passive graphics cards are great for media rigs, except that they tend to be small... mATX or ITX and and you might have trouble getting that into some/many media cases.

Passive 4770 with 1GB, I like it.... except that it won't fit where I want it to go :/

strap a 120mm zalman casefan underneath and you have something that cools vaporx style and is very silent

wondering how much more expensive these will be though.... cause the 4870 1gb is dropping in price

we all went nuts and bought them when you could get them for $400(au)...now you can get them for around $325(au).

Are they 10.5"?
I don't like 10.5"

since when were zalman fans silent?...

I'd kill for two silent 9800GT in SLI...

since i bought my first one 6 years ago, without exception since.

I think Zalman invented Quiet Computing... just recently in some reviews their latest coolers were deemed to be "louder", but that doesn't mean "loud" when the comparison term is something you can't hear.

Mine is barely audible. This is by far the quietest setup I've had.

ZALMAN CNPS9700
ZALMAN ZM-750HP
ZALMAN ZM-F1

and ZALMAN MFC2 to regulate all of the fans.

Great products. Great Cooling. Almost completely silent.

Looks quite decent. Wish we had the clock speed specs.

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).

this heat sink + good mod fan = crazy overclock

I've had plenty of Zalman fans, none of them are silent even at 5v.
They all make a distinct hissing noise, probably from their bearings.
