The testbed configuration is the following:

• 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 tried to produce the the highest possible temperature inside our test PC using the OCCT v2.0.1 software with a custom 30mins (mixed) operation.

We left both CPU cores running at full load for ~30 minutes. All temperatures were logged using the CoreTemp 0.99.3 and the software. We also followed two overclocking 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: 1.64V
• Other BIOS values: Auto

We measured the produced noise with a Precision Gold N09AQ Environment Meter. All measurements were made at a distance of 30cm away from the cpu cooler running at full speed. For all the coolers we used the same thermal compound from Tuniq, the TX-2.
