GlobalWIN CAK-II 16

The CAK-II 16 may look like just another plain old ordinary copper based heatsink but it does implement some great technologies and features which puts this HSF above many others. The base is made from Copper C1100 and is 60 x 60 x 30 mm in size. About the average size for a copper based heatsink due to the fact that copper does weigh more than aluminum or other material used to make heatsink and must be kept to a certain size to prevent putting too much stress on the motherboard socket.

So what makes this HSF different than any other copper one out there? The fin design, shape and distribution. The fins which total 74 are "S" shaped and very thin which creates a better surface area for heat dissipation. The more surface area the more heat that can be transferred from the cpu. Also the fins are placed closely together which allows for more fins to be placed on the heatsink. Again the same idea, the more fins, the more surface area, and the more heat dissipation. Also the base of this heatisnk is quite thick as well which plays a big role when wanting maximum cooling. The thicker base allows more heat to be transferred off the cpu onto the fins and then sucked off by the fan. Also the base when received is very smooth and polished to perfection.

The CAK-II 16 comes with a 60 x 60 x 25mm fan which has a thermal sensor mounted underneath the fan motor. The point of this is that when that sensor reads the temperature of the heat from the cpu it changes the fan rpm speed to accommodate for the difference in heat. You can see the sensor in the picture below on the right.

For example if the cpu is idle and running cool the fan will run slower and therefore quiter. If the temperature begins to rise the speed of the fan will increase to help push the extra heat away. Below is the chart showing the fan speeds at different temperatures.

As you can see the higher the temperature the higher the fan speed, fan noise and airflow. The lower the temperature the vise versa occurs. This is certainly a great feature the GlobalWIN has implemented into the CAK-II 16.

Now the clip on the CAK-II 16 may look like the ordinary clip on most HSF's but there is a difference between this one and the others. One the standard clip there were be some type of groove or catch on only one side of the clip which is the side that is placed last. Well GlobalWIN has placed a catch on both ends of the clip so that motherboad s which are cramped around the socket or a case with the power supply placed vertically can use a screwdriver to put the first side in as well. No more having to play around with the HSF to try and grab the socket. This is a very good idea.
