Gráfica Swiftech Introduces the Full-Cover Caldera HD4870X2 Water Block

[PsySc0rpi0n]

Introduction:

The Caldera 4870X2 is a hybrid cooling system for AMD HD4870X2 reference graphics cards. It is composed of two separate elements: a water-block that cools both GPU's, and a passive heatsink to cool surface mount components (memory, voltage mosfets, I/O chip).​

Compared to monolithic solutions, the primary advantage of uncoupling the cooling elements is to optimize the cooling capacity and the thermal joints for components that need it the most: the graphics processing units.​

The Caldera 4870X2 water-block utilizes Swiftech's proven Diamond Pin Matrix technology to cool the GPU's and guarantees superior thermal dissipation to promote the highest possible overclocks.​

Sweet!

a koolance tambem ja lancou um waterblock para essa grafica

foi muito mais eficaz que o arrefecimento a ar... até quando lhe fizeram OC ate ao maximo a temperatura manteve se bastante boa!

Este é interessante, porque separa o cooling dos GPU's do resto. É uma solução boa para quem já tem 1 ou 2 blocos GPU only, onde basta comprar o dissipador que cobre a grafica inteira.

Mas mesmo o bloco inteiro é pratico, porque é só 1 tubo a entrar e outro a sair e ao separar, melhora a eficiencia.

Aproveito o tópico;

SAPPHIRE Technology is now introducing the SAPPHIRE ATOMIC HD 4870 X2, an exclusive new dual GPU water cooled version of the standard ATI HD 4870 X2 card. Because the article is written in Greek which is not my strongest language, I'll stick to the specs and pics, after all that's all we need. As usual, the SAPPHIRE ATOMIC HD 4870 X2 comprises of two complete HD 4870 graphics systems on a single PCI-Express card connected by an on-board PCI Express Gen 2 bridge chip. Each GPU has 1GB of GDDR5 memory, making a total of 2GB on-board memory. Core clock speed for this model is 800MHz, there are 2x800 stream processors, the memory clock speed is 1000MHz with 512-bit memory interface. What's so special in this model is the full cover liquid cooling provided by the famous OEM cooling expert Asetek. The water-block cools both GPUs, all memory chips, the bridge chip and all the power elements. Two Dual Link DVI outputs are provided as well as TV-Out. Additionally the card's bundle includes a CCL UV lamp and Sapphire USB memory stick with drivers. The card will be available starting December 18th for a MSRP of $649.

Chipset: HD 4870 x2

RAMDAC: 400MHz x2

Memory clock: 1000MHz GDDR5

Memory interface: 256-bit + 256-bit

Memory Support: 2x 1GB

Cooling: Single slot liquid cooling

Bus Interface: PCI-Express Gen 2.0 x16

Variable display outputs: Dual DVI, HDTV out, VGA & HDMI via adapters

Max 3D resolution: 2560x1600 (dual-link DVI), 1024 x 768 (TV out)

Hardware Features: DirectX® 10.1, ShaderModel 4.1, Software Feature ATI AvivoTM
