Report: graphics cards and thermal characteristics
by Damien Triolet
Published on April 20, 2010

Radeon HD 6970
The reference Radeon HD 6950 and 6970 share both the same cooling system and power stage PCB.

A standard AMD cooler design is used with a fan and vapour chamber. Like the Radeon HD 5870 but unlike the Radeon HD 5850, an aluminium plate covers the back of the PCB.




Infrared thermography

System at idle.


System in load.


Graphics card at idle.


Graphics card in load.

The card is well cooled, both in load and at idle.


Temperature and noise readings

The readings confirm the above observations. You can see that the air expelled from the casing is very hot and noise levels a little higher than on the previous generation. Note however that the fan speed varies a lot during heavy processing, which can be annoying.
