Arctic Cooling Liquid Freezer 240 AIO CPU Cooler Review

Arctic Cooling claims its new Liquid Freezer 240 is "Extremely Powerful yet Quiet," "Designed for Extreme Cooling Performance" and that it has "Optimal Heat Dissipation." This All-In-One CPU cooler has a 240mm radiator that is poised to do great things with a stock Push/Pull 4-fan configuration and excellent cold plate.

Results: Temperatures

For our stock testing our retail purchased Intel Core i7-4770K will be kept at 3.50 GHz with a minimal 1.00v. For overclocked CPU testing, we will be running our Intel CPU at 4.4GHz with 1.25v. Idle temperatures will be recorded after a twenty minute period of inactivity. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes. Load temperatures will be recorded after a twenty minute period for air cooled systems, and 30 minutes for liquid cooled systems, at 100% load. To obtain this load we will be using AIDA64 Extreme Edition v3.00.2500. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes.

Please note we start our charts at 25C which is the ambient temperature at the time of testing. Since we are not testing an active cooling system such as a chiller or Peltier cooler, it is impossible for the temps to be less than ambient. This is why we start our charts at 25C.

Arctic Cooling was not messing around when they designed the Liquid Freezer 240. Even though running a kit like this on a stock CPU doesn't make much sense we can see how efficient the Liquid Freezer 240 is at transferring heat away. Some coolers perform best when a lot of heat runs through them but the LF240 is able to transfer heat quickly even when there isn't a lot of it.

4.4GHz Overclocked CPU

I was excited to test this cooler out after seeing how well the smaller Liquid Freezer 120 performed. I am happy to report the bigger Liquid Freezer 240 has exceeded all expectations. The Liquid Freezer 240 is able to cool our CPU better than any other cooler tested and even cools the CPU better at overclock settings than the stock cooler is able to cool it at stock settings. The best part of this is the standard size of the cooler. This isn't some oddly shaped, huge hybrid cooler. It's your industry standard 240mm radiator with some fans on it. If you have a full-size ATX case you can run this. Smaller cases would need to mount the kit externally to enjoy the immense performance this brings.

Sound Profile and Loudness

To test the sound output of the fan we first start by disabling all other fans in the PC. The decibel meter is located four feet away from the test system, and then we collect the dB data in the systems various configurations.

How on Earth Arctic Cooling got four fans to spin this quietly while performing this well is beyond me. The sound profile of these is so low that numbers just don't do it justice. The fans are just so quiet that I never noticed them. Sure you can hear them when you try to but otherwise they just fade into the background without any effort. It is a marvel to behold when you turn on the power for the first time and you think yourself, "Did I connect all the fans?". Yes, yes you did.
