TEST RESULTS

BASELINE, with Integrated Graphics: First, here are the results of our baseline results of the system with just its integrated graphics, without a discrete video card. We'll also need the power consumption reading during CPUBurn to estimate the actual power draw of discrete card later.

HIS HD Radeon 5870 Turbo

Upon installation of the card, we were surprised by how quiet the cooler was, even double-checking that the fan was spinning. This changed once the latest Catalyst driver suite was installed unfortunately. Sitting idle at a cool 33°C, the GPU fan was spinning at about 2500 RPM, generating a rather high system noise level of 21 dBA. The acoustic profile was broadband overall, with a touch of whine, excellent if the card had been on load, poor though since it was idle. We discovered through MSI's Afterburner application that the fan was set to spin at 50% speed until the temperature reached 50°C. Using the MSI utility, we managed to drop the fan speed to the minimum allowed and were rewarded with a significant reduction in noise. With the fan speed tweaked, the fan was just audible and the GPU temperature increased by only 4°C when idle.

When placed on load using ATITool, the fan speed was too aggressive at 2680 RPM even though the GPU had barely cracked 60°C. FurMark pushed the fan into overdrive, producing an earsplitting 34 dBA. This was the first time in our VGA test system's history that the AC power draw surpassed 400W and the cooler had a hard time keeping up. The GPU core temperature stabilized at 86°C even though the fan was spinning at an incredible 4300 RPM. You can alter the fan curve with Afterburner, but if you stress the card to its limit, you're going to have to run the fan fairly fast.

At stock settings, the HIS 5870 Turbo is the loudest card we've encountered. Given the card's high power draw and heatpipe-less heatsink we aren't too surprised. In actual use, the power draw and noise level should be a lot lower however as games are not as demanding as the synthetic stability test offered by FurMark. The least HIS could have done was to reduce the idle fan speed, as we managed to do using MSI Afterburner. The card is pretty much barebones with minimum accessories and no fan or overclocking utilities provided by HIS.
