This is what we really want to know. The Twin Turbo Pro may look good, but does it perform? Afterall this is the whole reason we replaced the reference cooler. So to establish whether the Twin Turbo Pro is a worthy upgrade it will be going head to head with the stock reference cooler on an ATI HD5870.
The testing methodology is simple. With the original stock reference cooler on our ATI HD5870 we will monitor the idle temperatures from a cold boot, then, following on from this, the card will be put through a meticulous stress test courtesy of oZone3D’s Furmark generating a full load state and thus pushing the temperatures up. This establishes the maximum temperature the HD5870 operates at under full load. This will be monitored for up to 20 minutes and the temperature recorded. Similarly, when the Twin Turbo Pro is installed on the graphics card the same testing process will be performed. This will produce an accurate evaluation as to whether the Twin Turbo Pro is an inferior or superior after-market solution compared to the stock reference cooler.
