Inno3D is excited to launch the i-ChiLL GeForce GTX 470 Black Series equipped with liquid cooling technology. The “full cover” water-block cools the GPU, Voltage Regulators, I/O chip, memory modules, and other critical components allowing for longer care-free gaming knowing your GPU is well looked after. This is definitely the ultimate cooling solution for enthusiast gamers.

In the i-ChiLL Black Series system, the water block first takes up the heat and passes it to the water flowing into it. Through the hose system, the water carries the heat to the radiator. Once it arrives in the radiator, the water passes the heat to the air via the ribs. The thinner the ribs and the larger the radiator’s surface is as a result, the more powerful the cooling system. The “cooled” water flows from the outlet side of the radiator back into the CPU water block. The air flow within the water block is also important in ensuring adequate cooling. That is because the more thermal discharge the water can absorb from the surrounding material in the block, the better the cooling performance.

Germany-based Aqua Computer is ready with its water-block for the NVIDIA GeForce GTX 480 graphics accelerator, the AquagraFX GTX480. The block is full-coverage and monolithic in design, and cools all vital heat-producing parts of the card. Its main unit is cut from a block of copper. The block weighs 850 g (1.87 lbs). It has a stainless steel top with laser-etched lettering on it. Aqua Computer used distance pieces for all threads. They are pre-assembled so users won’t have to fumble around with them. All surfaces which have contact to the GPU/RAM/VRM are high gloss polished (mirror-finish). The block also comes with a small backplate that cools voltage regulators on the reverse-side of the PCB. The company will start shipping these from next week, at a price of 89.90 EUR or around US $101 excl. VAT.

ASUS’ Republic of Gamers MATRIX series of graphics cards is getting a new member, the EAH5870 MATRIX. This model, based on the ATI Radeon HD 5870 GPU has high-end construction, cooling, and voltage regulators, out of the box higher clock speeds, overclocking headroom, and twice the amount of memory: 2 GB. The cooler and backplate design resembles that of ASUS’ GeForce GTX 285 MATRIX.

The clock speeds on this card stand at 900 MHz (core) and 1225 MHz (memory, 4900 MHz effective). The card seems to have a stronger VRM circuit that supports higher clock speeds. It draws power from two 8-pin PCI-Express connectors. Display connectivity includes one each of DVI-D, HDMI, and DisplayPort.

Overclocker-friendly features may include ASUS’ VoltageTweak software voltage control, a “safe mode” button that falls back to failsafe clock speed and voltage settings, among other things. There is no word on its availability, though we expect to learn more about this card at the upcoming CeBIT event.

Scythe is announcing today a new High-End TOP-Flow CPU Cooler by the name "Grand Kama Cross", which is the successor of former Kama Cross CPU Cooler. Grand Kama Cross is based on an X Structure layout using total of four 8 mm copper heatpipes for fast transfer of heat from the copper base to the aluminum fins. Thanks to the X Structure Design, easier mounting on CPU sockets as well as higher compatibility to tall RAM and Northbridge coolers are accomplished. By using the angled fin shape, airflow is redirected to allow additional cooling of surrounding components such as RAM, Northbridge and Voltage Regulators. For the optimum airflow, new Slip Stream 140 mm fan is first introduced with Grand Kama Cross CPU Cooler. PWM support allows flexible fan speed in a range between 500 and 1,300 rpm, automatically controlled by the motherboard creating airflow from 46 to 119 m³/h and accordingly 27.2 to 69.93 CFM. Both Slip Stream 140 mm fan and Grand Kama Cross CPU Cooler are using standard 120 mm fan mounting holes which allow the use of common aftermarkets 120 mm case fans as a replacement.
