SUMMARY: Interesting design, moderate performance and noise.


The good guys at Antazone were nice enough to send a sample of the Antazone AS-C1000 to check out.

Key Features

  • Three heat pipes with radial fin pattern
  • Copper fins and base
  • Fan speed 2200 rpm, 50 cfm, 25 dBA
  • Universal retention bracket for Intel P4 / 775 and AMD K8 / K7

The AS-C1000 features a radial fin construction which utilizes focuses airflow outside the hub area:


The base is well finished; I used the Poor Man’s Flatness Test on it with good results:



Parts that ship with the unit include a universal bracket for Intel P4 / 775 and AMD K8 / K7:


Installing this unit requires removal of the motherboard as the backing plate fits on the back of the motherboard; I found the installation a tad awkward as you install the bolts through the backside of the board while holding the heatsink and top mounting plate and, at the same time, tightening the bolts to hold the heatsink in place – I did it but a third hand would have been nice.

See the Installation Instructions for a full explanation of the approach.

The Test

The Antazone AS-C1000 was tested on an Asus P5WD2 motherboard P4 Motherboard Test Platform with a modified Pentium D 805 to read CPU case temps (both supplied by Directron).

¹MBM on-die temperatures.
²50 dBA measured 8″ from the fan intake corresponds to about 30 dBA measured 3 feet from the fan, a very quiet noise level.

Results place the Antazone AS-C1000 in the lower rank of heatsinks tested to date (Heatsink Ranking). Fan noise was moderate.


The Antazone AS-C1000 features an interesting design radial fin design; performance is moderate with low fan noise – a good looking cooler for non-aggressive use.
