Cooling/CPU Cooling by piotke @ 2004-06-12

ALPHA is back with an improved AMD XP heatsink, the S-PAL8055F, does bigger mean better? Does it stand a chance against the SP-97?s heatpipes? Time to find out!

Piotke's Test Setup
CPU AMD Athlon XP 2400+
Mainboard Asus A7N8X-E dlx
Cooling - Alpha S-PAL8055F
- Thermalright SP-97

Three different 80mm fans were used:

Low noise/rpm:

SANYO 80mm 109P0812M701
  • Airflow: 20.13 CFM
  • Noise: 21 dBa
  • Nominal speed: 2000rpm
  • 80x80x15mm

    Medium noise/rpm:

    Delta 80mm AFB0812SH
  • Airflow: 46 CFM
  • Noise: 40dBa
  • Nominal speed: 4000rpm
  • 80x80x25mm

    High noise/rpm:

    Delta 80mm FFB0812EHE
  • Airflow: 80.16 CFM
  • Noise: 52.5 dBa
  • Nominal speed: 5700rpm
  • 80x80x38mm

  • Room temperature: 25°C
  • No case used
  • Thermal paste: generic compound

    At default Athlon XP speed and core voltage the new S-PAL trails by 4-5 °C. You have to keep in mind that the SP-97 is the best AXP heatsink around at the time of writing. So the performance of the new Alpha can hardly be called "bad", just not as good as the SP-97. :)

    The Medium noise/speed fan was used in this test

    In the second batch of test I raised the core voltage to 1.85 V, this increases the heat output from ~68W to ~75W. Since heatpipes’ efficiency increases further when the heat output rises we see the SP-97 pull away. The S-PAL keeps the CPU’s temperature under 50°C and will give the end-user some headroom for overclocking.

    Onto the conclusion ->
