DEEPCOOL GAMMAXX S40 CPU Cooler
This tower has 41 fins stacked on these heat pipes, but you can see that all four of them aren't simply lined up. To help get each pipe some airflow, they are staggered in the fins to allow the fan a chance to remove heat from all of them directly as well.
When you look at it from the side, the pipes appear to be lined up, but it is an illusion. You also notice that this tower has an open side configuration as well as being able to house two fans, one on each side of the tower.
The back edge of the fins is the same shape as the front edge, but you can see that there are little holes in the back edges and they have fins in them to help direct the air from the middle of the cooler to exhaust through the back as these direct that flow.
I also angled this image a bit to show how deep and easy the grooves are to access when clipping a fan on this with the wire fan clips that are provided.
Looking at the fins from the top you can now see the 24 holes at the trailing edge of the fins along with the embossed DEEPCOOL name that is designed into each and every fin in the stack.
The top of the base for this cooler isn't just flat, when they extruded the aluminum to be used to solder in the heat pipes, they also skived the top of it to allow air to flow through and remove a bit of heat before it even gets out of the base.
Here you can see that DEEPCOOL sends the GAMMAXX S40 with thermal paste already applied. All you have to do to get this cooler installed is add some hardware, DEEPCOOL was sure to take care of the rest for you.
I removed the paste so that we can now see the four copper pipes and the aluminum base. You can see they are all milled at one time, and even though there are slight gaps in this design, the surface as a whole is levelled off nicely.
Getting a little closer to the heat pipes you can now see the stagger more easily, and you can also tell that the find are just pressed onto the heat pipes. There is also a bit of the bottom four fins that got removed, and this is to allow AMD mounting clearance for DEEPCOOL's clip system.
With the fan now back on the cooler, you can see from the side that the fan steps down behind the blades. This allows for air near the front to be easily sucked in, and slightly more concentrated as it leaves the fan and enters the cooler.
Looking from the front with the fan in place, you can tell that the tower is quite compact with this 120mm fan covering a large percentage of the fin area. There should be no issues supplying air into these fins as well as a little at the bottom to cool the motherboard.
