All of our tests were performed with our ambient room temperature at a comfortable 23c. To determine our idle temperatures we let the machine idle in Windows for 30 minutes, then we fire up Crysis Warhead to heat up our GPU to generate the heat that determines our results. After gaming testing is done we also run the card through a Furmark torture test just to see how well the cooler works under conditions that it would not normally be subjected to. The fan on our 5830 will be left on auto to help determine the true ability of the cooler.
The cooling on the HIS 5830 works very well. Our idle temperature was 35c and we hit 60c playing Crysis Warhead. With the fan on the 5830 set to Auto our temperatures never passed 68c during our Furmark testing and the fan speed never passed 61% which is very good considering the stress Furmark places on a graphics card.
