PRODUCT PICTORIAL & WALKTHROUGH
Let's take a virtual walk around Sapphire's version of ATI's HD4770.
Sapphire chose to use a simple, yet effective cooling solution on the RV740. Seeing it is a cooler running chip thanks to the 40nm manufacturing process, a huge cooler will not be needed.
The cooler, although not directly connected to the five 64meg DDR5 chips, it does bow a constant supply of cool air directly to the die face so it can be cooled passively through moving airflow. this does helped with the overclocking which I will be covering later and keeps the core at about 35-40c during idle and just over 50c during load even without a substantial cooling solution.
Seeing this is a rather simple card, there is little else to point out other than the voltage regulators being attached to a passive metal cooling plate for stability and the inclusion of a 6 pin power connection for your power supply. There isn't a whole lot to point out other than the connections.
The back of the card is simple and unobstructed so that it won't interfere with any motherboard northbridge cooling solutions. Direct temperature testing with an infrared thermometer resulted in a temperature of only 50c on the portion of the card directly under the VPU core.
Last but not least in this section is the main connection panel. You have three choices which consist of two DVI monitor connections which you can adapt to a VGA or an HDMI equipped monitor through their respective adapters, or you can take advantage of the video-out port to output HD or standard S-video/composite video signal.
