Crysis Warhead
Furmark 1.8.2

For testing today we have attached a diode to the core to ensure software reporting is accurate. We are testing in real world conditions with Crysis Warhead on a 24 inch screen at 1920×1200 with a high combination of IQ settings. We then run Furmark 1.8.2 which is a fantastic stress test to show absolute worst case scenarios. It is important to point out that Furmark doesn't mirror a ‘real world' gaming situation which is why we also test with Crysis Warhead.

Room temperatures are maintained at a healthy 25c which is a reasonable figure for most people. Just adjust our findings with a + or – celcius variable to match your own environment.

We were stunned by how good the cooler was, so much so that we reran the tests ten times, for stress periods of up to an hour. The HIS HD5870 OC never once hit 50c, hovering around 47-49c. This is a 24c improvement over the HIS iCooler V Turbo solution and a whopping 36c improvement when compared to the reference HD5870 cooler. The overclocked Accelero XTREME plus powered HD5870 was actually running cooler when gaming than the reference HD5870 was doing nothing.

We then wanted to measure the time it took for the video card to return to idle from full load temperatures. This is an often missed aspect of a coolers performance. For instance the Noctua NH D14 takes much less time to return a fully loaded overclocked processor to idle resting temperatures than a reference cooler.

A mere 4 seconds later after full load, the Accelero XTREME Plus had returned the core temperatures to the reference point. This is twice as quick as the iCooler V Turbo solution and 9 seconds faster than the reference cooler (which was also running hotter in the first place).
