Cooling/CPU Cooling by SidneyWong @ 2004-08-25

Cooljag V558A

CoolJag V558A has the typical Socket A cooler look, using 70x70x25 mm fan and three lugs hold down design. It has alum fin and base with copper facing. Unlike the 66IC, V588A does not have thermal speed sensor, it runs on a single 3,000 RPM speed.

While the base finish is second to 66IC, it is better than others I’ve seen.

    AMD XP Test Bed

    Lazyman's Test Setup
    CPU AMD Athlon XP 1700+@2100Mhz – 1.75v vcore
    Mainboard Abit NF7 v1
    Memory 1 * 512Mb PC2700 Apacer
    Video ATI Radeon 9000 Pro

    Everything is installed in an X-Dreamer case with window panel fan blocked but features:
  • 2x 80mm intake
  • 2x 80mm exhaust
  • 1x 80mm top-blower

    – all turning ~2,200 RPM

    Arctic Silver 5 was used with these tests and ambient temps remained the same at 25-26°C

    I was hoping that I would not encounter the same problem with the 66IC. Indeed, the installation was painless and fast.

    The SF-609 temp probe reading is within 2°C to both NF-7 and NF7-S board BIOS readings I own; therefore I will skip the probe reading chart. Here, the V558A shows superiority over the 2L.

    Onto our conclusion ->
