Taking a closer look at the heatsink, you will see many promising features. The 925CA has a 2900RPM 90x25mm fan, which is considerably larger than the stock heatsink which is only 70x10mm. This greatly increases the heat dissipation of the cooler. Another characteristic the 925CA has is larger surface area. The heatsink spreads out farther from the heatsinks rectangular base out to 90mm to compliment the 90mm fan. This way the large fan blows over the entirety of the dense fins on the heatsink, providing the best possible cooling.
One of the drawbacks to the heatsink is its finish. The lapping process of the 925CA offers the user a flat finish to ensure flat contact with the processors integrated heat spreader. The major issue with this is the finishing process has left the heatsink base with a rough finish, which is clearly visible to the eye and to touch.
Here you can see the base of the heatsink is very rough. Each of the white lines are imperfections in the base of the heatsink. This means the processor and the CPUís Integrated Heat Spreader will not be making as much contact with the base of the heatsink. In most cases, this leads to higher temperatures than if the heatsink was finished more finely with fewer scratches. Now that we have taken a closer look at the 925CA, itís time to install the heatsink and see how it performs.
