FrostyTech has posted a review on the Coolermaster Aero1 ASB-V73-U1 Copper Heatsink



Remember the German-born Noisecontrol Silverado heatsink that came out a few years back? Well the Coolermaster Aero ASB-V73-U1 uses a similar configuration, with a few distinctive differences of course. Where the Silverado used a rather lack-luster extruded aluminum heatsink - albeit coupled with a pure silver disk - the Coolermaster Aero1 uses a full copper skived body. The Silverado also used two squirrel cage fans for air delivery because of their lower noise output. Coolermaster use a relatively loud squirrel cage fan on the Aero1, though it is a custom unit that exhausts air over an area of about 50x55mm. Squirrel cage fans have a couple of benefits over standard vaneaxial fans when it comes to lower-noise heatsinks, though they don't tend to deliver nearly as much air. One of the prime reasons these types of fans can make a good air delivery source for a heatsink is that their exhaust is uniform - in other words there are no dead spots. A vaneaxial fan on the other hand will tend to have a dead spot right below the motor. Since most fans sit squarely up on the heatsink itself this puts the dead spot directly above the hottest section of the heatsink.
