Test Setup

For ou tests, we used XFX's HD 7970 Double Dissipation card, on which we used different coolers with the provided thermal compound applied for each coolers. We used AMD's CCC 12.8 to control fan speeds and GPU-Z for the monitoring part of both fan speeds and GPU temperatures. We used HWInfo for the VRM temperature monitoring. Room Temperature: 25°C

For the noise level results, we measured the noise level using a decibel meter (Voltcraft SL-200) located at 1 meter away from the graphics card.

• Idle, temperature is taken after 5 minutes @ 30 %, 50 % and 100 % fan speed.
• For FurMatk, temperature is taken after 10 minutes of GPU Burn test @ 30 %, 50 % and 100 % fan speed. (1920 x 1080 (60 Hz), 8x MSAA, Full Screen)
• Highest temperature reached under Call of Duty Modern Warfare 3 @ 30 %, 50 % and 100 % fan speed after 1 hour gameplay.
• Highest temperature reached under BattleField 3 @ 30 %, 50 % and 100 % fan speed after 1 hour gameplay.
• Highest temperature reached by the VRMs under BattleField 3 (after 1 hour gameplay) and at idle (5 minutes after boot) with auto fan speeds.
