GeForce 9800 GTX+
The GeForce 9800 GTX and GTX+ come, like all top end NVIDIA cards, in a rather large format similar to the Radeon HD 4870 X2. The card therefore takes up a lot of space, especially as it has a double slot cooling system. It expels hot air from the casing. The GTX+ variant uses a G92b clocked at a higher frequency than we have tested. There is little temperature difference between the two versions however because the increase in frequencies is compensated by the finer engraving process of the GPU.

Graphics card in idle.
Graphics card in load.
In idle the card almost doesn’t heat up at all, which is quite a difference to the Radeons. In load however, behaviour is similar to the Radeon HD 4870 for example in terms of the system as whole, but with the graphics card itself better cooled.
Temperature and sound level readings
Although the termperature of the card is better managed in load, noise levels are up. The air expelled from the casing is less hot, which is logical.
