Today we review what we believe to be the best performing VGA cooler, as the new Thermaltake ISGC-V320 hits our test bed. This product is massive, spanning the length of a high-end GeForce GTX graphics card, which allows it to support a pair of 120mm fans. The huge design allows for not only low load temperatures, but also near silent operation...

When we reviewed the new Thermaltake DuOrb Extreme just a few weeks ago, the results amazed us. The original DuOrb was far from impressive, with a load temperature of 83 degrees on our overclocked GeForce 8800 GT. Incredibly the DuOrb Extreme was able to reduce the load temperature to just 45 degrees, matching our best ever recorded result with the Thermalright T-Rad².
