Here we will take a closer look at the heat sink and how it's mounted. This heat sink from Arctic Cooling is a low profile design that is designed to be used in small form factor cases and is one the HTPC crowd should love based on the height alone. This design uses two heat pipes that feed into the aluminum fin array to dissipate the thermal load from the CPU. The 92mm Fluid Dynamic bearing equipped fan is mounted on top of the Freezer 11 LP so you have a downdraft design that should help keep the surrounding electronic components cool. The dimensions on this little cooler are 115mm x 106mm x 53mm(H). That's just over 2 inches tall if the metric system is not your bag. With its diminutive size you have to wonder how well it will cool by comparison to the Intel supplied cooling solution.
When you strip the Freezer 11LP down to its bare essence you have the elements that make up a potent heat sink. You have a copper base, 2 large heat pipes that feed through the base and a series of aluminum fins to get rid of the heat. All in all a simple layout that has been used many times before with excellent results.
The heat sink has a 92mm PWM controlled fan rated to run at 12v with a power draw of .15A at a speed of 900-2000 RPM. The CFM is rated at 27 and the fan also has a fluid dynamic bearing. The fan is mounted on the top of the aluminum fins with the dual heat-pipes running completely through the fins. The copper base is covered with Arctic Cooling MX-2 thermal compound. You may want to remove a little bit of the thermal compound as I found out, they do put a very generous amount on.
The solid copper base is flat but does not have a highly polished finish. A polished finish is a luxury that takes more time and money to execute that really does not pay huge dividends and really is not needed so no harm no foul on this point. This finish should be fine for the 90 watt maximum heat load specified for this cooler.
The cooler is just a little taller than the ram installed next to it. One thing you do have to take into consideration with this heatsink is the clearance issues with it's very short/wide stance; as can be seen by the heat-pipe extending over the NF200 chip and the cooler completely covering the chokes, some versions of mosfet or chip coolers surrounding the CPU socket may cause a conflict. Here is also a picture of just how short this cooler really is.
The mounting is a very simplistic and effective method. You place the bracket across two mounting holes and insert the white adapters into the holes and then just place the black pins into the white adapters which spread them to secure it to the motherboard. The heatsink is then secured by 4 mounting screws that are threaded into the black brackets previously mounted to the motherboard. This is about the easiest heatsink I have ever installed.
Now to the specifications and features and then testing.
