ASUS High-End EAH4890 Cooler Pictures and Details Emerge
April 14, 2009 by Cabro · Leave a Comment
Towards the end of March, we caught a glimpse of a yet to be named high-end custom-designed Radeon HD 4890 accelerator from ASUS. The accelerator makes use of an exotic VRM design to facilitate high clock speeds and overclocking potential. Back then, we couldn’t get pictures of what cooled the beast. Thankfully, NordicHardware has a few pictures of the cooler, along with more details in place.
The cooler is a complex piece of engineering. It consists of a central copper GPU contact base from which six 230 mm long copper heatpipes distribute heat between the GPU and VRM areas, which have large heatsinks of their own. Two fans of dissimilar sizes are suspended on the shroud. The larger one, over the GPU, rotates clockwise, while the other counterclockwise. Looking at ASUS’ design methods with high-end cards, we can safely guess the fans are controlled by a complex controller that adjusts fan speeds on a per-fan basis, depending on the temperatures of the various zones of this card.
From what the source tells, this cooler should run the card at least 10 °C cooler than what the reference cooler manages. This may facilitate stock clock speeds in excess of 900 MHz for the core, and 1000 MHz for the memory. Some credit of the electrical stability of the core at those speeds goes to the use of the Fujitsu-made SuperML capacitor, that reduces voltage noise by as much as 20% (from 143mV to 114mV). Regarding the exact brand name of this card, we can confirm that the card will not carry the “MATRIX” branding. The other high-end term ASUS uses, “TOP”, has already been used for a factory-overclocked reference design accelerator, leaving the brand name yet to be disclosed.

Two days after the start of the new Nvidia G200 generation aquacomputer presents the aquagrafx G200. The cooler is produced from highly purified electrolysis copper and provides an extremely high cooling capacity. Due to the up to 20mm broad channles inside the block it has an extremely low flow resistance.
The copper plate of the cooler is approx. 8 mm strong and weighs approx. 660 g completely. It is CNC milled from a solid raw part of almost 2.2 kg of copper. The GPU area is covered by an optimized cooling surface which offers around. 25% more surface than the one used until now.
The GPU, video chip, RAMs and voltage regulators are covered by the block. Altogether, 17 components on this card are cooled by the aquagrafx G200. The connections are G 1/4″. The price will amount to EUR 94.90. The delivery starts 25th of June 2008, but preorder is possible already.
Coolink GFXChilla GPU Cooler Review
February 24, 2008 by Cabro · Leave a Comment
Coolink isn’t a name which anyone outside of Europe has heard much about but they are ready to make their North American debut in the next few months and with it they will bring some very interesting cooling solutions to our shores. As a company, Coolink isn’t actually a stand-alone enterprise but rather it is the retail arm of the Kolink International Corporation which has acted as an OEM manufacturer for some of the most popular heatsinks on the market today. They are also partnered with Noctua in order to provide R&D support but Coolink represents their main foray into the retail marketplace. Since Coolink’s inception, they have been mostly focused on the European marketplace but as their stable of products has increased in size, so too have their aspirations of expansion into the lucrative North American marketplace.
Spearheading this push into North America is their new graphics card heatsink; the aptly-named GFXChilla. This cooler represents Coolink’s first graphics card heatsink and with it they are aiming straight at some of the most popular graphics cards on the market: the 8800GT and HD3870. Even with compatibility for these two best-selling cards, the GFXChilla also boasts compatibility for nearly every other graphics card made within the last few years including the Nvidia 7×00-series, 6×00-series as well as ATI’s X1800 and X1900 series. This broad compatibility coupled with the fact that Coolink advertises this as a silent, dual-slot cooling solution should make the GFXChilla a very popular choice among consumers.
The one thing about the GFXChilla that stands out the most is its price since our contacts tell us that once it hits Canadian retail shelves, it should retail for about $30CAD. This represents a 35% savings over the Thermaltake DuOrb and a whopping 45% savings over the Thermalright HR-03 GT. However, the GFXChilla doesn’t have any lofty expectations of taking the performance crown away from either of these two other heatsinks since it is billed as a drop-in replacement for a stock cooler with focus on silence rather than all-out performance. Performance aside, as we will see later that Coolink has provided some innovative additions to the GFXChilla in order to improve cooling performance by replacing the stock 80mm fans.
While a warranty of 3 years on any cooler is extremely competitive, the GFXChilla will be in tough company in this review. It will be competing against the massive HR-03 and the Thermaltake DuOrb while being asked to perform up to our expectations on the highest-end card it is compatible with: an 8800GTS 512MB.
