Sunbeamtech Core-Contact Freezer LGA1366

3. How we test

For our tests we used an open air testbed with the following configuration:

  • 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.
