The compact-sized Freezer 11 LP brings low noise cooling into low profile and HTPC Systems. With a height of 53 mm only, the cooler squeezes into even the tiniest PC cases.

  • newegg Compact and Lightweight With dimensions of 115 (L) x 106 (W) x 53 (H) mm, having a weight of only 255 g, 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.
  • newegg Reliable Cooling Performance Equipped with an ultra-quiet 92 mm PWM fan and two copper heatpipes, the Freezer 11 LP offers a maximum cooling capacity of 100 Watts. The dual high performance 6 mm heatpipes efficiently dissipate the heat from the CPU into the block consisting of 50 aluminum fins.
  • newegg Quick Installation The unique mounting system via push pins offers excellent stability and is applicable within minutes. The pre-applied ARCTIC MX-4 thermal compound makes the installation a clean process. The cooler is compatible with Intels socket 1155*, 1156 and 775. (*May not be compatible with all Mini-ITX mainboards.)
  • newegg Whisper-Quiet 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 92 mm PWM fan makes the entire operation to be nearly inaudible. The exclusive fan holder design reduces the unwanted noise by absorbing the vibration from the spinning impeller as well.

3 out of 5 eggsExpensive but for some of us necessary.

Pros: It is a big improvement over the stock coolers and it has a small footprint making it fit in most tight spaces. It is barely bigger and the socket that it covers but it is still bigger so if the fit is tight measure before buying. It is also affordable.
It is pretty silent, surprisingly quiet for such an inexpensive cooler.

Cons: It is nothing compared to a real cpu cooler costing $40 and upwards. So if you really want to be sure to overly adequately (and we all do) cool your cpu then spend the money.

Other Thoughts: It is great as a spare cooler to just keep around in case you suddenly need it. The other cheap coolers are totally inadequate from my experience.

5 out of 5 eggsPlucky.

Pros: -Incredibly quiet
-Performance slightly above copper-cored Intel stock coolers
-Relatively low profile
-Pushes air over components around CPU, at least in two directions
-Moderately polished, extremely flat base
-4-Pin connector for PWM support
-Two years in operation, not a hitch
-Modern and legacy socket support
-Simple instructions & easy installation

Cons: -Pipe clearance is a make-or-break deal depending on your board
-Not a high performance solution for extreme overclocking
-Works best with a side fan feeding it fresh air directly

Other Thoughts: Make sure that your board has sufficient clearance for the pipes in at least one direction, or it simply won't fit. Those pipes can make things awkward if your CPU is surrounded by high VRM sinks and the memory modules are very close to the socket.

This thing runs whisper quiet at idle. Sitting on top of an overclocked E8400, it performs better than the copper cored Intel heatsinks with none of the noise. LinPack pushes 55C and P95 pushes 51C, where the copper/alu Intel cooler was 67C and 62C. Even at high speed, it remains fairly quiet.

Does fit Gigabyte P35-DS3L and EP45-UD3R.

3 out of 5 eggsToo wide, blocks mem on MB

Pros: Looks good. Previous good experiences. It comes with thermal paste already applied.

Cons: This cooler blocked the 4th DIMM socket of DRAM on my MB.
I'm building a system with micro-ATX form-factor using the ASUS H97M-PLUS motherboard and an Intel CPU for the LGA 1150 socket.

1 out of 5 eggsGarbage (literally)

Pros: I cannot think of any, it's decent looking?

Cons: I was in the market for a quiet solution to replace my stock i3 cooler. After reading reviews I purchased this. I don't know if I had a defective one, but this thing was actually a good bit louder, and my CPU temp jumped up to around 80 degrees. For days I tried adjusting the fan speed, didn't really make a difference.

I just replaced this with the Noctua NH-L9i 95mm SSO2 CPU Cooler, which I'm extremely happy that I did. This Noctua is extremely quiet, and even with the low-noise adapter on, my CPU is now around 38 degrees.

5 out of 5 eggsPerfect for basic slim tower

Pros: -Much better than stock coolers
-Easy install
-No movement if installed properly
-Pre applied thermal compound

Cons: -Does not fit well with memory that has a big heat spreader on most mATX boards, that's more of a tip than a con so im not gonna knock an egg for that.

Other Thoughts: Ive used about 9 of these now in recent slim tower builds, these are basic builds nothing extreme. They are used in offices so they are running 24/7 and the room temps aren't great. In the previous 3 I have built its been in cases with only front and back venting and does the job fine. I have had zero issues with the 9 ive bought at different times so no inconsistency in quality. On the original 2 I used I had installed with Corsair Vengeance memory and it was too tight of a fit, I have switched to the Vengeance LP memory and it fits fine.

All slim tower mATX builds, 4 have been i3-4130, 2 have been i5-4570 and 3 have been i3-4150

I'll be continuing to use these on future LGA 1150 builds

1 out of 5 eggsToo tall

Pros: N/A

Cons: This cooler is taller than the stock Intel cooler for i7/LGA 1150. Don't know what about this cooler makes it "low profile" or "HTPC ready".
What's much worse is that the specified height (53mm) is shorter than the stock Intel one (60mm), and yet this cooler is taller than stock. This wasted a lot of time.

4 out of 5 eggsGood

Pros: Works well in mini-itx build. Cools i5-2500k in my mini-itx build well.

Cons: Is rather wide, be cautious of the motherboard you select to put this on. I used ASUS P8H61-I R2.0 ( ), where it almost blocks the PCI-E slot, and does block one RAM slot.

Other Thoughts: This was my first mini-itx build, just a warning to anyone considering doing a similar thing.

3 out of 5 eggsIts a cpu cooler

Pros: Better heat dissipation over OEM I think.. Good fan, quiet, fit, was easy to install

4 out of 5 eggsThis is not for ITX

Pros: Cooling is Great, Arctic Cooling is great for any price, quiet, efficient PWM Speed controlling.

Cons: Too big for my Cramped Mini ITX boards. Could not get it to fit in any configuration that I tried and used the Stock cooler instead.

Other Thoughts: Great cooler although it did not fit my needs it is great for larger than Mini ITX Motherboards. Memory gets in the way on one way and the video card gets in the way on the other. but if you are using a Micro or Regular sized ATX Board this would be a great Cooling solution for those with not a lot to spend on cooling but still want the quiet best performers.
