Gigabyte's VGA Cooling Resembles Car Radiator
Gigabyte's new GV-R577SL-1GD features an impressive, passive cooling system.
Monday GIGABYTE announced the GV-R577SL-1GD, a new AMD Radeon HD 5770 graphics card featuring an internally-developed Ultra Durable VGA technology and Silent-cell cooling design. The latter technology provides a passive approach to cooling using four high-performance heat pipes and two additional fins. Encompassing the entire surface of the PCB, the cooling system resembles a car's radiator grille and looks quite impressive.
"GV-R577SL-1GD is comprised of 4 high-performance heat pipes which are connected to the ultra-huge copper base plate," the company said. "By adopting ultra-huge pure copper base with 4 heat pipes, heat can spreads effectively from hot areas. In addition, GV-R577SL-1GD enhances the overall cooling capability by utilizing the precision process to deliver zero-interval combination between heat pipes and fins. Furthermore, 2 additional fins increase 52.87% surface area to dissipate the GPU temperature."
GIGABYTE said that--when compared to other cards--the Ultra Durable VGA Technology provides 10- to 30-percent more overclocking capabilities, 5- to 10-percent lower GPU temperatures, and "excellent" power efficiency, decreasing power switching loss by 10- to 30-percent. Ultra Durable VGA also features a 2 oz. copper PCB board, Samsung and Hynix memory, Japanese solid capacitor, Ferrite /Metal Core Chokes, and more.
With a core clock of 850 MHz and a memory clock of 4800 MHz, the new GIGABYTE card comes packed with 1GB of GDDR5 memory and support for DirectX 11, Eyefinity, Stream, CrossFireX, and more. Although the product is not yet available on the GIGABYTE website, more information can be obtained here. Unfortunately, pricing and availability was not provided.

wow it all heat sink
That looks really nice imo, can't wait till they put it on other products.
I wonder how heavy that thing is...
This grill will make rappers jealous.
That's surprisingly nice looking. I wonder how it performs? With that much surface area I'd imagine it'd work quite well.
Zoom zoom zoom.
I am not a big fan of passive cooling. I tried with a single 9800gt, it heated up to 121c. Needless to say I went back to active cooling.
Very nice to see some new performance fannless cards coming out.
Cool but in no way resembles a car radiator. That would require liquid and a fan.
I have enough air flow in my case as it is now. passive cooling for the vcard would just reduce the noise created from my box which would be very nice.

Not the full radiator, learn to read the article and not just the title.

Passive cooling relies on the native airflow of the case, rather than having an onboard fan on the card. Your card heated up so much (most likely) due to poor air circulation where the passive unit was.
Looks great now (hopefully performs great too). But put it in a standard users case for a while and you get to spend 2 days cleaning all of the dust out of all the individual fins.
Thats ridiculous! I am sure that will take up more space in your case, i could be wrong. BUT that thing will increase temperature in your case! they should focus on a cheap water cooling system. I like the original HD5000 series cooling method.
Will be good for HTPCs that have decent airflow. A system with good airflow is a must for passively cooled systems.

That's right.. this is the only cooling fin arrangement made that resembles a car radiators fins, right? I don't need to read the article. The title lead me to believe something else. This has happened on numerous occasions.
Gigabyte has been a big player in high performance with passive cooling. I've used such designs in their 7600GT and 7600GT. The big advantage is that there is 0DB noise coming from the card - okay, I am assuming that.
With a big case cooler fan, it helps to suck out the heat generated by the radiators.
As shown on this ATI5770, the 2nd slot is used as an exhaust vent. This CUSTOM design use used by Gigabyte and looks very much like my 7600GT from years ago... and it was HUGE back then.
For heat issues, I switch to BIG-FAN coolers like HIS graphics cards which come with ICE coolers, which I had before my 7600GT. My 4670 is ICE and silent.
Paid $180 for my 7600GT - Passive and $80 for my 4670

this is why air duster cans were invented...prob solved
Nice design! I'll give Gigabyte some respect for trying something outa the norm.
Seems like 95% of graphics cards come with a little factory reference fan and thats the end of it. Unless you mod it yourself or find a solution like this your stuck with the norm.
This should be good. IMO since I like cars I think it's quite nice. Just hope the performance and cooling lives up to expectations.

Or in really bad cases (dust + smoke = super caked on dust/sludge) I use CRC's Lectra-Motive. In the garage or driveway, mind you.

Seriously?!? have you ever actually CLEANED anything with a can of air. Probably not. I have a Zalman 9700 and the fins on it get caked with stuff that will not just blow off. So your "problem Solved" isn't really.
Instead of air duster, I used leaf blower for my garden to blow the dust out of the case. This should only be attempted outside of the house. You'll be surprised how much dust will be out of you case with HUGE VOLUME of AIRS =)
YMMV...
Reminds me of what Powercolor did with their GO-Green version of the 5750.
@slickyfats
Agree. Cleaned out my brother's 4 year old Athlon x64's heatsink and a silent graphics earlier this year. I resorted to wrapping a square of toilet paper around a business card and using that to pull the dust out from the fins.
I am afraid that it will brake the connector or even the motherboard! How much that beast weights?
The size of that heatsink is ridiculous but passively cooling a modern graphics card is pretty badass.
This is quite great card. But the cooper will look nasty after years of use.
121 degrees C?? Dude ... the possibilities ...
Who wants some tri-tip? Just got me a new grill (poking at the meat laying on the radiator)
Not to mention the weight: 2 of these + Vertical Mobo = SNAP!! NOOOOO !!
I wonder how far I can overclock this baby if I somehow added a fan to it
hm.........................

Also a fine way of checking if any components are loose -- as they fly away across the garden !!
Mlop maybe you shouldn't over think shit and you wouldn't have that problem. To me "resembles" is a far cry from "working" like a car radiator.
Now with that said while it does look cool. While I'm not a nvidia fan anyways I would never buy one made from gigabyte again. I like their mobos but I'd diffently gonna stay away from any cards they make.
