Temperatures & Overclocking
Our testing involved running Furmark's Stability Test and running the benchmark until the temperatures had levelled out. Given Furmark's intensive nature, this didn't take much time...
Unsurprisingly, the HIS Radeon HD 5850 was very quiet throughout our testing. The target load temperature, like other branded cards we've tested is 80*c, which it reached and held with a fan duty speed of just 33%.
Our overclocking endeavours were limited to ATi's Catalyst Control Centre utility, which allowed us to reach speeds of 775MHz on the Core and 1125MHz on memory. The utility does not permit a higher overclock (no doubt to distance the 5850 from it's faster sibling) but we believe that other utilities will see the graphics card to much higher frequencies.
Enough chit chat. It's time for some games testing.
