Temperatures & Power Consumption
While inherently convenient, the Inno3D 8800 GT suffers from its single slot cooler design as this overclocked version reached 94 degrees under load. This was 6 degrees higher than the ASUS 8800 GT which uses the same single slot cooler but is not overclocked from factory. This made the GeForce 8800 GT considerably hotter than the GeForce 8800 GTX and even the Radeon HD 2900XT. The Radeon HD 2900XT produces considerably more heat, though because of its large dual slot cooler and high-speed fan it does remain reasonably cool when under load.
For typical 2D usage the Inno3D 8800 GT appears to use just 40 watts of power which is quite conservative. When under load in a 3D application such as Crysis, the Inno3D 8800 GT can use around 47% more power as the combined system consumption reached 259 watts.
This puts the Inno3D 8800 GT on par with the 8800 GTS (640MB) graphics card for power consumption. Given the 8800 GT was significantly faster than the 8800 GTS in almost every game tested, this is remarkable. Under load the 8800 GTX consumes 17% more power and the Radeon HD 2900XT sucks down 28% more power than the 8800GT.
