GeForce 7950 GT Launches With Passive Cooling 168

Posted by Zonk
from the hot-to-cold dept.
An anonymous reader writes "NVIDIA's GeForce 7950 GT comes with great performance at an attractive $299/£225 launch price. Incredibly, XFX's pre-overclocked card comes with a passive cooling solution. From the article: 'There is no doubting that NVIDIA's GeForce 7950 GT is faster and cheaper than the GeForce 7900 GT that launched at the same price point earlier in the year. There is a lot to like about the product, and there is even more to like about XFX's implementation. It's generally a match for ATI's Radeon X1900XT 512MB in popular games.'"

      The thing that I like about passively cooled system components is that cooling duties can be taken care of by larger fans than could ever be put onto a component (in this case, a video card). Those larger fans can move more air per minute at a lower RPM and therefore at a lower noise level. Even when the noise level isn't that much lower, it's also at a lower frequency due to the RPM difference, and those lower frequencies are often more easily ignored.

If you had a box that had little in/out airflow then the heat build-up in the case would make any cooling solution ineffective, so
