Water cooling specialist Danger Den is ready with its full-coverage water cooling block for the NVIDIA GeForce GTX 295 graphics accelerator. Consisting of two PCBs holding a GPU system each, the GeForce GTX 295 is a complex piece of machinery, with regards to installing third-party cooling.

The Danger Den block (model: GPU-6850) is monolithic and is installed in a way that makes it sandwiched between the two PCBs. Contact-points on either sides of the block convey heat from the GPUs, memory chips, VRM, NVIO2 processors and the BR-03 chip. The block is available from Danger Den with a variety of options with regard to the fittings. SLI fittings that relay fluid between accelerators in an SLI system are optional. The block weighs 4 lbs (1.81 kg). It is priced at US $189.95.

NVIDIA's 55nm GeForce GTX 200 series cards seem to be doing well at the markets. Cashing in on their success, EVGA plans to release GeForce GTX 285 and GTX 295 accelerators which are ready for water-cooling. While not much is known about the specifics of water cooling the GTX 295 part comes with, the GTX 285 SKU comes in the form of cards with factory-fitted water blocks.

NVIDIA made several changes to the PCB of its single-GPU G200 PCB, making GeForce GTX 280 water blocks incompatible with the GTX 285 PCB. The new PCB has a rearranged memory layout, with all its memory chips positioned on the business-area of the PCB, and a re-arranged VRM area. The new EVGA Hydro Copper block is designed to be a monolithic full-coverage block with a copper base. The SKU most likely to be carved out using this block could be the EVGA e-GeForce GTX 285 Hydro Copper. The company could take advantage of this superior cooling to set extremely high factory-overclocked parameters to the GPU and memory. This is the same company that released the GeForce GTX 285 FTW with audacious clock speeds of 720/1,620/2,772 MHz (core/shader/memory) using the NVIDIA reference design cooler. As with all water block-fitted graphics cards from EVGA in the past, the company could charge a premium over all its air-cooled GeForce GTX 285 models.

Introducing the Caldera cooling system for AMD HD4870X2 graphics cards from Swiftech. 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 the rest of the components such as the GDDR5 memory, voltage regulators and the I/O chip. The Caldera 4870X2 water-block utilizes Swiftech's proven Diamond Pin Matrix technology and premium copper baseplate for the highest cooling performance. Additionally, there's a built-in white LED that illuminates throught the clear acrylic sides of the GPU water block when in operation. The full-cover water block weights in 411g and has a MSRP of $159.95. It is available now. Inside the package you'll also find 1/2" barbs, (2) plugs, thermal pads, Arctic Céramique thermal grease, mounting screws and installation guide.

After Corsair dropped off some of its latest Dominator 2 DDR3 memory kits for testing with the new Nehalem platform, various sites immediatelly acknowledged that there're some changes in the DHX coolers that cool the new memories. The new approach will be called DHX+ and it consists of a modified thick-sink design where an additional fins are bolted on the top of the cooler. Now HEXUS.net has unveiled that the DHX+ technology will also offer enthusiasts to futher cool the memory by attaching a water cooled TEC block on top. The block appears to be still in development, so we'll have to wait a little bit more until more information is available. The Pelt/waterblock combination should allow extra voltage to be pushed through appropriately selected RAM modules without killing them, potentially yielding higher clock rates and lower latencies.

Recently water cooling guru Swiftech unveiled new revisions of two of its well known parts, the MCW60 GPU water block and the MCRES Micro reservoir. Let's start with MCW60-4870, a special revision made exclusively for AMD's ATI Radeon HD4870 video cards. This is Swiftech's first graphics water block to combine both heatpipe and liquid cooling in one package. Based on the award winning MCW60 water-block which employs Swiftech's proven Diamond Pin Matrix technology, the MCW60-4870 base plate is CNC machined from billet C110 copper, then electroless nickel and chrome plated. It cools the GPU, memory, and using a massive heatpipe extends the cooling area to the graphics card's mosfets. This product is compatible with AMD's HD4870 reference design graphics cards only. It is available now for $89.95.
Second comes the MCRES Micro Revision 2 reservoir. It shares all the good things that characterized the classic MCRES Micro in size, quality, and provided accessories, but it also includes additional enhancements and functionalities that have been requested by enthusiast users. The most noticeable feature is an additional port at the bottom of the unit, that can be used as an alternate outlet, to feed a second pump, to plug-in a temperature sensor or as a drain. Revision 2 also uses new 1/4" BSPP (G1/4) plugs made of high polish chrome plated brass, for both the fill-port and the alternate outlet port. A vent was also added to the anti-turbulence baffle to eliminate the formation of a small air bubble that occured in the previous model. The MCRES Micro Revision 2 is available now for a MSRP of $25.95.

Not long time since the first air coolers for Core i7 showed up, German water cooling expert aqua-computer has decided to let us know that some of their high-end cuplex series CPU waterblocks including the cuplex xt, cuplex xt di and cuplex hd are now also available with conversion kits/mounting brackets to suit Core i7 LGA 1366 sockets. The Cuplex XT series is one of the best CPU blocks offered with an attractive look and 100% German build quality. It is made out of two parts, a high-quality copper base, and a translucent blue acrylic top. The Cuplex XT fits only G1/8 threaded fittings, a G1/4 version is also in the works.

Swiftech updated today its portfolio to include a GT200 adapter kit for its MCW60 Revision 2 GPU water block. This adapter will make the current MCW60 Rev. 2 GPU blocks compatible with all reference NVIDIA GeForce GTX 260 and GeForce GTX 280 video cards. The MCW60 waterblock is a liquid cooling solution for high-end graphics processors. It uses the same base plate technology as the award-winning Apogee CPU water-block and offers easy integration in most water cooling loops. Until now the block was compatible with most ATI and NVIDIA video cards thanks to various base plates. This latest GTX 200 hold-down kit will cost you $6.99. Please visit Swiftech for more information.

Germany's top quality water cooling manufacturer aqua-computer has recently released a new processor water block. Named aqua-computer cuplex hd it has the following characteristics:

• low resistance high flow / double impact design
• 99.99% pure electrolyte copper base plate
• G1/4" in and out diameter
• Compatible with Intel Socket 478 and LGA775 processors only

The aqua-computer cuplex hd is available now for EUR 49.90.

Fluid-cooling specialist Danger Den is ready with its Radeon HD 4870 X2 series water blocks designed to provide high-levels of thermal control to facilitate overclocking. The block provides full coverage cooling to the front part of the PCB that holds all the main components. The memory chips on the rear of the cards might still require passive cooling by means of heat-sinks.
