Sapphire Vapor-X CPU Cooler Review

Thermal Performance Test Procedures:

  • Idle temperatures are obtained after sitting at the desktop for 15 minutes.
  • Load temperatures are obtained after running Prime95 in the ‘Small FFTs’ mode for 15 minutes.
  • We repeated testing with our CPU overclocked to 4.6GHz (46x multiplier, 100MHz base clock) using a BIOS-set voltage of 1.300V.
  • The cooler’s fans are set to 100% to eliminate inaccuracies due to dynamic PWM fan speed adjustments.
  • The supplied thermal paste is used to provide an accurate interpretation of the cooler’s out-of-the-box performance.
  • We use HWMonitor to measure the CPU temperature.
  • CPU temperature recording is accurate to +/- 0.5°C.
  • Ambient temperature recording is accurate to +/- 0.05°C.
  • Ambient temperature was maintained at 21°C.

Acoustic Performance Test Procedures:

  • We measure the noise output of our entire system from a distance of 1m while the CPU cooler’s fans operate at 100% (indicating the maximum noise output).
  • We set the case fans to minimum speed (hence noise) and avoid using a discrete GPU to isolate the CPU cooler’s noise output.

Test System:

  • Processor: Intel Core i5 3570K.
  • Motherboard: Asus P8Z77-V.
  • Memory: 8GB DDR3 1333MHz.
  • Case: NZXT Phantom.
  • Cooling Fans: 1x 120mm 1900 RPM Scythe Kaze Jyuni (front intake), 2x 120mm NZXT (side intake), 1x 120mm NZXT (rear exhaust), 1x 200mm NZXT (roof exhaust)
  • Graphics card: On-board.
  • Power supply: 1000W Seasonic Platinum-1000.
  • Storage drives: 128GB Kingston V100 (OS), 1TB Samsung F3, 300GB Western Digital Caviar.
  • Thermal Paste: As supplied with the cooler.

Software:

  • CPUID HWMonitor.
  • Core Temp (additional certification).
  • Prime95.
  • Windows 7 Professional 64-bit.
