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.

this upcoming 40nm chip but we do know that RV870 is codenamed Little Dragon. This is a performance chip and it is the base for R800, a dual RV870 card.

Little Dragon is a rather interesting codename and we know that we can expect this card in 2009, possibly even in 1H 2009.

This is definitely going to be one of the first 40nm cards around, at least from ATI’s workshop, and we’ve heard that Nvidia wants to go down the same 40nm path.

Traditionally, ATI was faster in transitioning to new processes, it did so with 65nm and 55nm and it remains to be seen if it can beat Nvidia to 40nm.

XpertVision is Palit's European VGA graphics cards brand. Only recently they released an announcement that the brands will merge again to become "Palit Microsystems Ltd.".

At the show we saw several new ATI based cards from Palit. Since their booth is located in the AMD hall, no NVIDIA cards were on display.

First up is the new Palit HD 4870 which does not use the AMD reference design. The cooler is equipped with two fans and is much quieter than the normal cards. The HD 4870 Sonic Dual features DisplayPort and a Turbo switch which allows you to change the clock frequencies on the fly. When in "Turbo" mode, the card runs at 775/1000 and 750/950 in "Normal" mode. Even in normal mode this is still an overclock over the AMD reference clocks.

The Palit HD 4850 Sonic is for the smaller wallet but still offers improvements. For example an 8-pin power connector is used instead of the usual 6-pin one. It also has a quieter fan and higher clocks than the AMD reference edition cards.

Last but not least, this "Gold Edition" card is basically a HD 4850 reference design board but with an improved cooler - at almost no cost. The clocks on this model are the reference design frequencies

The GeForce 9400 series succeeds the 8400 series. It is expected that the 9400 GT offers twice the level of performance as its predecessor, the 8400 GS. TweakTown posted the first pictures of cards made by MSI. The first picture shows the 512 MB variant(model: N9400GT-MD512H), the second shows the passively cooled 256MB variant (model: N9400GT-MD256H). The cards come equipped with DVI, D-Sub connectors and a HDMI port on the card. Don't be mislead by the flashy packaging of this card - showing a knight with a sword (that's not a surfboard) - these cards serve primarily as entry level accelerators for media / HTPC purpose with some very casual gaming thrown in. According to TweakTown, it hits the shelves on August 26

MSI has decided to make a nice looking system that has four HD 4870 cards which are placed in an acrylic case.

The showcased system isn't anything new as the HD 4870 has been around for a while, but the fun starts when you place your hand near the cards' exhaust. It gets really hot as we are talking about four cards that are packed tight in a small case. As far as we could tell the heat pushed out of the exhaust could easily be compared to a smaller hair dryer.

That's just the way things go now, powerful cards produce a lot of heat. Here is a picture of that system.

HIS digital company usually equips AMD video cards with excellent cooling systems. Similar alternative products formed the series iceQ.

Here is the photographs of HIS radeon HD 4850 IceQ 4 Turbo. The transparent ice cover hides the decent sizes radiator. The cooler base is accurately made from copper .The memory microcircuit memory and power elements are equipped with their own radiators.

This video card has a 512 mb GDD3 memory , for the turbo model the frequencies are increased from default 625/1986 MHz to 650/2000 MHz.. The cost of this model in Japan is equal to $225.

Thermalright company released a new video card cooler intended for NVIDIA video card (GTX 280 and GTX 260) , In this case the compatibility is limited to those two cards due to the difference in location of the mounting holes between different NVIDIA cards generation .

This cooler (Thermalright HR-03) include 6 heatpipes , two heatsinks (soldered) to maximize the cooling capacity , Heat pipes soldered every heatsink to increase the heat transfer efficiency ,Nickel-plated heatsink , two ways of mounting the cooler on video card . Moreover Thermalright includes the PWN-IC heatsink adapted for the best heat dissipation .
