Today we are also looking at the baby brother of the Freezer 13, the AC Freezer LP 11. The cooler is not exactly a competitive cooler to the rest of this roundup, we have decided added it to the mix. It is a low-profile CPU Cooler for Intel platforms and and HTPC. The compact-sized Freezer 11 LP brings low noise cooling into low profile and HTPC Systems. With a height of 53mm only, the cooler squeezes into even most tiny PC cases.

- Specifications

- Retail package

The packaging of the Freezer 11 LP is a plastic clam shell encasement indicative of a retail package with the cooler and mounting hardware enclosed. The accompanying cardboard sleeve has the specifications and features listed as well as the compatibility information.

Arctic Cooling's Freezer 11 LP heatsink is compatible with Intel socket 775/1156 processors only. Socket 1366 Intel processors are not supported, nor are any AMD platforms.

The Freezer 11 LP heatsink ships with a pile of little plastic components that create a secondary mounting platform on the Intel motherboard for the small heatsink to attach to with long machine screws.

Equipped with a quiet 92mm PWM fan and two copper heatpipes, the Freezer 11 LP offers a maximum cooling capacity of 90W. It features two performance 6mm heatpipes to dissipate the heat from the CPU into the block consisting of 50 aluminum fins.

With dimensions of 115(L)*106(W)*53(H)mm, having a weight of only 255g, the Freezer 11 LP is extremely compact. It fits virtually into any low profile PC case and is the ideal choice for any HTPC system. Below you can see how small this cooler really is:

Arctic Cooling's Freezer 11 LP heatsink is comprised of two sections, a ~100x80mm heatsink fin stack and a thin 92mm fan integral with mounting bracket and fan shroud. The fin stack is comprised of nickel plated fins which are soldered to a pair of 6mm diameter copper heatpipes that run along the bottom and through one side to the other. The 92mm PWM fan spins at speeds of 1200-2000RPM, exhausting air down through the 32mm thick fin stack.

If you remove the fan, you will see a simple layout and the basic elements of the heatsink: 2 large heat pipes that feed through the base and a series of aluminum fins to get rid of the heat.

The copper base is covered with Arctic Cooling MX-2 thermal compound. The solid copper base is flat but does not have a highly polished finish, although it should be fine for the 90 Watt maximum heat load specified for this cooler:

- Installation

The motherboard need not be removed from the case to install the Freezer 11 LP heatsink. Once installed the heatsink can be unscrewed and reinstalled with ease.

The mounting is a  very simplistic and effective method. You place the bracket across two mounting holes and insert the adapters (white ) 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.
