We reported, last week, as Sparkle has proposed its own version of video card GeForce 8800 GT NVIDIA equipped with cooling system completely passive, both GPU for video memory. It seems that this business is not the only, as Taiwan emerge from the first images of a video card Gainward characterized by a similar approach.
The card uses the reference design developed by NVIDIA, differentiating only for the massive cooling system, if for the reference board NVIDIA has used a system with cooling fan can occupy only a single slot on the motherboard, in order to ensure an effective dissipation closed Gainward has chosen a massive building that has a total of two slot.
A cover almost the entire surface of the PCB is a massive aluminum radiator with basic copper in direct contact with the GPU GeForce 8800 GT and in direct contact with the memory chips.From the middle 4 heatpipe copper bear the heat generated by GPU direttamernte towards a second radiator, positioned above the card and equipped with numerous cooling fins.
It is good to remember as cooling systems of this type, in order to operate effectively, always require the presence of an adequate replacement air inside the houses, and without this, in fact, we run the risk of creating hot spots near the video card, without the cooling system can be adopted to speak out dissipate the heat generated by the video card and risking possible with this system malfunctions.
