Sapphire R9 290X Tri-X 8GB CrossFireX Review

Temperatures

The cooling solution which graphics card vendors choose to implement is one of the main differences that consumers have to contend with when choosing a graphics cards. Apart from their acoustic properties, the thermal properties of graphics card coolers are extremely important. Lower temperatures are always better and with AMD and Nvidia opting to use dynamic overclocking algorithms that take temperature into account it is important that graphics card vendors use high performance cooling solutions in order to maximise performance. The era of graphics cards reaching dangerous temperatures are now in the past but the importance of lower temperatures still remains. Lower temperatures mean better stability, longer component longevity and lower fan speeds .We take temperature readings after 5 minutes of three different load scenarios: desktop idle, Furmark load and Unigine Heaven load. We always record actual temperatures and make a note of the ambient. In the case where more than 1 GPU is used an average is created.

So here we see the CFX configuration holding the middle of the pack. The two cards combined produced a little more heat than the single card, but due to the immense cooling solutions used, it was kept under control, showing just a difference of 8°c at full load between the single card and the CFX setup.
