HTPC's are now part of our lives, and this requires sometimes descent cpu coolers with low height so they can fit inside the small HTPC cases. To day we will have a look at Arctic Cooling Freezer 11 LP, a low profile cpu cooler with 2 heatpipes, and a 92mm fan.



Will it be able to perform better than its competitors?



The features and specifications are taken from Arctic Cooling website.


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.


Compact and Lightweight

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.

Reliable Cooling Performance

Equipped with an ultra-quiet 92mm PWM fan and two copper heatpipes, the Freezer 11 LP offers a maximum cooling capacity of 90W. The dual high performance 6mm heatpipes efficiently dissipate the heat from the CPU into the block consisting of 50 aluminum fins.


Quick Installation

The unique mounting system via push pins offers excellent stability and is applicable within seconds. The pre-applied ARCTIC MX-2 thermal compound makes the installation a clean process. The cooler is compatible with Intels socket 1156 and 775.


The Freezer 11 LP is a very quiet cooling solution. Even when the fan is spinning at its full speed at 2,000 RPM, the low noise impeller in the 92mm PWM fan makes the entire operation to be nearly inaudible. The patented fan holder design reduces the unwanted noise by absorbing the vibration from the spinning impeller as well.

Now let's have a look at the packaging!



Freezer 11 LP is inside a blister pack, so we can see the cooler.


From behind we can see the features and specifications.


Inside we will find all the necessary hardware to mount the cooler, an AC sticker and the user's manual.


Let's have a closer look!



From the top Freezer 11 LP seems quite impressive, and the black-white colours make a nice combination.


From the side we can see the 2 heatpipes, and also notice how low is the Freezer 11 LP.


From the other side.


At the bottom we can see the contact surface with preapplied thermal paste.


We can see that the contact surface is not mirror finished, but is perfectly straight.One more thing to notice is that the heatpipes are soldered to the fins and not only to the base. This results in even better performance.


Here we can see the Freezer 11 LP with the fan removed.


The product sticker of the 92mm fan.


Let's have a quick look at the installation process!



Installation is very easy and does not require to remove the motherboard. First of all we have to place the 2 plastic brackets, and insert the white pins.


Then we simple press the black pins inside the white ones to secure them.


After this we simply place the Freezer 11 LP and secure it with the 4 screws.


Here we can see how it looks at the motherboard.


Now let's see how it performs!



Heatsink testing methodology

  • Each heatsink test consists of two parts, Real Test and Synthetic Test.
  • Real Testing is performed in a real system, while Synthetic is done using methods that simulate thermal loads.
  • Stable thermal loads are used in order to have accurate results, more specifically thermal load is produced by power resistors.
  • The thermal load wattage is 30,60,90,120,150,180,210 watts. This covers a really wide range of processors and also overclocked states at wattages of 180 and 210 watts.
  • Temp readings are taken from a sensor inside a copper plate that is the exact size of the processor tested in order to simulate the cpu with the best way.
  • For reading the temperature I am using a high sensitivity digital multimeter.
  • Thermal paste used in each test is Noctua NT-H1 because it has very quick break-in time.
  • The copper piece that simulates the processor is not perfectly sanded, because the actual processor heatspreaders are never mirror polished.This happens again to have as accurate results as possible.
  • Sound pressure levels are measured with a high sensitivity digital sound pressure meter, from 20cm away of the cooler inside a sound proof box to eliminate any external noise of echo.


In order to have more clear results Arctic Cooling Freezer 11 LP will be compared with:

  1. Intel Stock cooler
  2. Nexus H.O.C. 9000


TESTING PART 1 - Real Testing


System used for the test







TESTING PART 2 - Synthetic Testing

Stable thermal loads are used in order to test the cooler at a wide variety of thermal loads, this test simulates cpu states from Idle to Overclocking




TESTING PART 3 - Sound Pressure Level

Intel Stock cooler is probably one the most silent coolers in the market. According to noise everything under 17-18dBA is considered to be innaudible, while noise over 50dBA is annoying for me and most people.









As we can see Freezer 11 LP outperforms HOC 9000 and Intel Stock cooler, and also has low noise levels.It is a bit noisy when it runs at full speed, but this requires a powerful cpu running at full load for a while, not the concept of an HTPC. The performance is very good if we consider the small size and the 92mm fan.Also the price is very attractive, and is cheaper than most low profile cpu coolers.



  • Good performance
  • Low noise levels
  • Low price



  • It can be noisy when running at full speed
  • It feels very plastic



"One of the best, in not the best, low profile coolers I have tested..."
