While not as hot as the record-setting Radeon HD 4850, the HD 4870 was still rather hot at idle, with a GPU temperature reading of 70°C. But that poses no problem for the card, and remember that with its traditional double-slot design, the hot air is vented outside the computer case (unlike the GeForce GTX 200 series), which is always a good thing.
Under load, the heat sink did its job and the temperature didn’t rise all that much – at least not as much as the little Radeon HD 4850.

The reference Radeon HD 4870 is not cool at work. The GPU temperature is as high as 78°C when idle and 89-90°C under load
The good thing with the X2 is that the cooler is dual-slot, and uses the colder air inside your PC to cool down the GPUs and then blows it away (exhausts) it at the rear of the card, outside of the PC.
By the way, a LOT of heat is disposed outside the PC by the 4870 X2. Here's something to think about. If you game long enough in Crossfire, a small room will actually warm up. I'm not kidding.
