• CPU: Intel Core7-920 Retail
• Case: Open Air testbed
• Motherboard: Asus P6T Deluxe Bios 1403
• Memory: 3x1GB Crucial PC3-1066
• PSU: OCZ 720W
• HDD: WD 80JB
• Operating system Windows XP with all the latest updates installed
• Software: OCCT v2.0.1 & CoreTemp 0.99.3
• Thermal Paste: Tuniq TX-2
• Idle time: ~30min
• Load time: ~30min
• RPM speed controllable via SmartFan BIOS or via external hardware controller

We produced the highest possible temperature using the OCCT v2.0.1 software and a custom 30-minute mixed operation:

We left both cores of our CPU running at full load for about 30 minutes. All the temperatures were logged using the CoreTemp 0.99.3 software as well as the OCCT v2.0.1. We repeated the procedure for two scenarios:

• Intel Core i7-920 @ 2.66GHz
• Vcore: 1.1000V
• Other BIOS values: Auto

• Intel Core i7-920 @ 3.60GHz
• Vcore: 1.26250V
• DDR3 Voltage: 1.66V
• Other BIOS values: Auto

For the noise measurements we used the Precision Gold N09AQ Environment Meter. All measurements were taken at a 30cm distance from the cpu cooler running at full speed. In the following pages you will see a comparison among many CPU coolers. For all the tests, we we used the Tuniq TX-2 thermal compound.
