GeForce 9800 GX2
The GeForce 9800 GX2 is the first bi-GPU card to use a sandwich type design in which each GPU is on a dedicated PCB, but both face each other with the cooling system in the middle. Hot air is mostly sent back inside the PC because the grill allowing it out is tiny on this card.

Given that the GPUs are placed near the front of the graphics card, that is where the heat is concentrated, with the back of the card carrying the turbine staying fairly cool.
Temperature and noise level readings
The card is less noisy than the Radeon HD 4870 X2, but is not however silent. Once in load, the temperature given off spreads around the system, just like with the Radeon.
