Hardware - Intel Core 2 QQuad Q6600 (3.00GHz) LGA775 - x2 Corsair DOMINATOR Twin3X2048-1800C7DF G Module(s) - Seagate 320GB 7200-RPM (Serial ATA300) - Inno3D GeForce 8800 GT (512MB) - ASUS P5E3 Deluxe (Intel X38) Software - Microsoft Windows Vista Ultimate SP1 (64-bit) - Intel System Driver 8.4.0.1016 - Nvidia Forceware 175.19

When plugged into the GeForce 8800 GT the Arctic-Cooling Twin Turbo result is impressive when compared to the Nvidia reference cooler, reducing the temperature by 32%. However when compared to other aftermarket VGA coolers the result is not that impressive. Plugging the Twin Turbo into the 7v adapter that is supplied with the card reduced the idle temperature by 4 degrees.

Interestingly, the operating volume barley increased when using the 7v adapter. The 12v adapter did increase the operating volume to a point where it was noticeable. The operating volume is now comparable to the Thermaltake DuOrb. Unfortunately the added volume only resulted in a 1 degree temperature drop.

When plugged into the GeForce 8800 GT the Arctic-Cooling Twin Turbo is more impressive under load, reducing the temperature by 39% when compared to the reference cooler. When using the automatic fan speed control of the GeForce 8800 GT the load temperature reached 54 degrees, matching the temperature of the DuOrb AX.

However, using the 7v adapter reduced temperatures further, allowing the Arctic-Cooling Twin Turbo to keep the GPU at just 46 degrees. The 12v adapter allowed the Twin Turbo to produce the best result we have seen on the GeForce 8800 GT, reducing load temperatures to just 43 degrees.
