MSI Graphics Cards At Computex: Thermo-electric Cooling And Other Innovations
The trend of implementing passive cooling onto low- and middle-end graphics cards has been obvious recently. There are several reasons, including stricter noise requirements and technological improvements (especially in case of NVIDIA's 90nm chips) further reducing heat dissipation. But, as said above, passive cooling was traditionally used in budget lower performance Radeon X1300, GeForce 7300, 7600GS cards, because of its mediocre efficiency.
MSI claimed it succeeded in developing a way more efficient passive cooling system. In includes a chip that monitors temperature and, when it exceeds 50°C, deviates it to a massive cooler via heat pipes.
No technical details on this 'Electric Thermal' solution were provided, but they claimed it could be used for the hottest cards. Though at the event they showcased the middle-end MSI RX1600XT Electric Thermal operating at 590MHz core and 1.38GHz memory clock rates.
MSI also demonstrated the Dual CoreCell technology in action. It can automatically increase and manage graphics card's voltage, clock rates and fan speed. Currently it's implemented into the new MSI RS1600Pro Diamond (450/800 MHz).
The trend of equipping cards with HDMI interfaces was also considered -- in RX1600XT-TD256E-HDMI and NX7300GS-TD256E-HDMI cards based on ATI and NVIDIA GPUs, respectively.
