The Arctic Cooling Freezer 13 PRO CPU Cooler
Looking into the mouth of this 300 Watts capable cooler you see a 120mm fan that consists of nine white blades and hub that get attached to the cooler body with the use of the black outer shroud. Under the 120mm fan you can start to get a glimpse of the Cross Blow fan, but the wiring has been folded and is tucked here for transit, which is blocking our view.
Trying to gain every advantage, the Freezer 13 PRO uses a closed side by bending the majority of the edge of the fins down. This keeps all the air flowing all the way through the cooler versus losing it; let's say 30%, right out the sides.
The back of the cooler has a "V" shaped wedge cut from the middle of the forty-seven fins. I can see a two-fold gain to this design. It may cause a void in the airflow, almost making the air stay centralized, and it obviously removes material, which can make the cooler lighter. We also get our first good view of the white Cross Blow fan on the base. This eleven blade 50mm fan is used to cool the heat pipes, as well as adding circulation under the body of the cooler. This should lead to cooler components surrounding the CPU as well.
The wiring for both of the fans is handles with one connection to the motherboard. Both fans are 4-pin, or PWM controlled. Even here there was a bit of thought for maintenance or even swapping the fan if needed. The fan on the front of the cooler simply unclips from the plug and allows you to remove the 120mm fan and leave the cooler in place.
I waited until this point to discuss the four 8mm diameter heat pipes that are used in the Freezer 13 PRO. Not only did I not have a clear angle for them, but I couldn't show the solder that is used to set these between the aluminum top half and the copper base. In this case, the base has MX-4 pre-applied to the surface, and I also found a few pieces of something in the material.
Since it had some debris in the compound, and due to the fact that we use AS-5 on every cooler to come through our doors, I scraped it off and took a picture. Mainly I wanted to show the amount of material applied to the base, in case you ever wondered how much is too much, this is the amount done on most coolers sent with thermal material pre applied, as a reference.
