Infrared cam snaps video card under load
 

In load we note that a small card like the Radeon HD 3450 facilitates circulation of the air, which helps the CPU and other zones of the motherboard to stay cool. To a lesser extent, a single slot card like the Radeon HD 4850 also facilites things at this level. On the other hand, a system made up of several graphics cards has an impact on circulation.


The air that is expelled from the casing by the Radeon HD 4870, 4890 and 4870 X2 is very hot and you have to make sure you leave a small gap between the casing and the wall.
