Zaward Gyre ZCJ010 CPU Cooler

Specifications, Availability and Pricing



The Zaward Gyre is an equal opportunity cooler capable of mounting all Socket 775 processors from Intel and all AMD sockets going back to 754. On the other side of the time table, Intel's latest and greatest is listed as are their hottest. Testing will show if processors like the quad core Extreme Editions are suitable for use with the Gyre.


The cooler is roughly 125mm square and 135mm tall. Three 8mm heat pipes are arranged in the typical U shape and run from a copper base (that is actually the heat pipes) to aluminum fins. This is where traditional goes south and innovation comes in. The fan is mounted on the top of the cooler, facing your case side panel. Air is blown down through a plastic shroud where fins redirect it through the cooling fins. I can think of two reasons why this method is better and one that may offset the advantage.


Fans have a dead spot behind the central mass where the magnets are placed and air is not pushed in this area. The real problem is the placement of the dead spot, directly in the middle of the cooler, right above the CPU core on down draft coolers, right where you want more airflow. On the new upright CPU coolers, the dead spot is in the middle again, but since you are relying on heat pipes to distribute that heat the effect of the dead spot is reduced. The Gyre takes the fans dead spot out of the picture and routes air to all of the fins with the aid of a plastic shroud.


The next benefit is also the downfall and without getting out all of the university books from the attic, the explanation will be dumbed down. If you are an engineer please understand that this is a technology website and not a place for me to get flamed for my understanding of physics.


On the benefit side, when compressed air changes direction it loses a percentage of audible noise. A good example would be a muffler on your car or a silencer on a gun. As air is forced to change direction 90 degrees inside of the Gyre shroud, it will lose some acoustic noise making the cooler quieter overall.


When air changes directions, its velocity is reduced and backpressure is built. When the new air from the fan is pumped into the shroud, the increased pressure makes the fan rotate slower and move less air.


All in all, we are only talking about a 120mm fan that is moving a relatively small amount of air when compared to an automobile engine or the pressures found in a .308 rifle. Still, the principals are the same.


Zaward is currently looking for a US distributer so availability in the US is very limited until such time. In Europe the Gyre will set you back right around 39€ and I would expect a similar price in the US market.
