Titan Dragonfly 4 Closer Look:
I measured the Dragonfly 4 at 157mm x 120mm x 48mm in size, and it weighs in at 483g (17oz.). The Dragonfly 4 is thin and light enough not to cause a concern about excessive weight hanging on the motherboard. The 48mm thick dimension (with a single fan) is what makes this cooler ideal for motherboard and RAM access as we see in the installation pictures at the bottom. The Dragonfly 4 uses a single 15mm thick, 120mm PWM fan (13 blades) to provide the airflow through the four heat pipe-equipped tower.
The Dragonfly 4 is a tower-style heat sink that uses a quartet of 5mm copper heat pipes to carry the thermal load from the contact face of the cooler to the aluminum fin array. One thing I notice is the way the heat pipes are arranged - in a line so that each pipe gets its own supply of air and air only passes a given heat pipe once. Some coolers stagger the pipes so that air passes by a series of pipes and I have to wonder if that has an effect on efficiency.
The outer edges of the fin array have a wave pattern that alternates every six fins. At the base there are holes for AMD and Intel mounting feet, but the unit comes with the Intel feet already installed. There is a second set of wire mounting clip included if you would like to add a second optional fan for a push / pull configuration. There are also little cooling fins formed into the aluminum heat sink base to help dissapate heat. Printed on top is the Titan logo and a blue dragonfly graphic, which add a nice touch.
The Dragonfly 4 uses a direct-contact heat pipe design, which allows the thermal load to take a more direct route to the large fin array. The surface is not smooth, but most direct contact designs usually aren't. Depending on the size of the gaps between the heat pipes and base material, you may need to use more thermal paste than normal when mounting the cooler. There is a protective film that needs to be removed before using the Dragonfly 4.
To keep the Dragonfly slim, a 15mm thick, 13 blade fan is used. Here you can see the fan and wire mounting clips that are used to secure it to the heat sink. The clips are, of course, designed for a thin (15mm) fan, and fans that size are not very common. So using a more standard 25mm thick fan makes sense, but it won't work with these clips. It would be a good idea to include some clips that would fit a 25mm fan.
The included fan is rated to run between 150±20% and 1500±10% RPM at 12V using 0.2A to consume 2.4W. Rated at between <5~<28.6dBA, the fan is quiet enough even at full speed that you can hardly hear it over your other case fans, while stll providing almost 53 CFM at an air pressure rating of 0.05 Inch H2O. The cable is sleeved for a sleek look and terminates in a 4-pin fan header connector.
Installing the Dragonfly 4 is straightforward. The base bracket is two-sided, so you can use it for an Intel or AMD installation. There are four bolts that hold the base bracket to the back of the motherboard. After the bolts protrude through the motherboard, you slide a small washer over each bolt, then screw each of the four spacers over the bolts. Now you are ready to attach the heat sink. I found it easier to remove the fan first. The final screws have springs to apply a constant load on the heat sink, then I like to apply the thermal paste for a test fit.
The small size of the Dragonfly 4 makes for a nice installation. You can access all of the motherboard sockets. Even if you add a second fan, you would not be sacrificing motherboard access. There is plenty of room to get to the RAM slots, as most large coolers cover your RAM.
