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.

Introduction

Today we are looking at the Liquid Freezer 240 from Arctic Cooling. When we recently reviewed the smaller Liquid Freezer 120 we were pleasantly surprised to see how well it performed in every one of our tests. It seems that Arctic Cooling has kept the same formula for the bigger 240.

In case you didn't know, Arctic Cooling has been around for a while and knows a thing or two when it comes to cooling the components of our PC. They have had some major success stories in the past so seeing a new line of products emerge from them is exciting. Arctic Cooling has never been afraid of trying new things and breaking from the norm. The field of all in one coolers continues to get more crowded with each passing year and as such it becomes more difficult to set yourself apart from the crowd. Arctic Cooling is hoping to strike gold a second time as they hit a home run when it came to the Liquid Freezer 120. So let's cut the chit chat and see if lightning can strike twice.

System Setup

Today's review takes place on our fourth generation [H]ard platform. The test bed consists of the ASUS Z87-Deluxe motherboard, eight gigabytes of Corsair 1600 MHz DDR3 RAM and the Intel Core i7-4770K.

Test Methods

CPU

The biggest change you will notice is the removal of hardware testing. In recent years, Intel has shifted its methods of testing to software based and so we find it acceptable to do the same.

GPU

Once again we have an integrated GPU in our processor which alleviates the need for a discrete one. With the removal of a discrete GPU comes the advantage of not having an additional variable to account for.

The iGPU will not create any anomalies in our testing as long as we practice consistent testing methods.

Case

Corsair was kind enough to provide us with its Carbide series chassis. It provides excellent airflow and interior space and is a good reflection on current case design.

Thermal Paste

Noctua's NT-H1 thermal paste was selected as the thermal interface material (TIM) of choice for a few key reasons. The thermal paste has been shown to provide excellent thermal conductivity allowing the heat sinks to better do its job. There is no observed curing time. That is, performance does not get any better over time. Any curing time could have introduced variables into the equation causing at best dubious results and at worst unreliable ones.

Temperatures

Ambient temperature will be kept at 25C for the duration of the tests and measured with a MicroTemp EXP non-contact infrared thermometer and cross referenced with the Sperry Digital 4 Point thermometer. Any variance greater then 0.2C will halt the testing until temperatures return within spec for fifteen minutes.

Idle

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

Load temperatures will be recorded after a twenty minute period for air cooled systems, and thirty minutes for liquid cooled systems, at 100% load. To obtain this load we will be using AIDA64 Extreme Edition v3.00.2500. This places an even greater load on the CPU than before and includes some benefits. Because the load is so extreme we see the temperature vary wildly from 72C to 86C in some instances. To get an accurate reading we will utilize AIDA64’s ability to average the temperature over time. Given twenty/thirty minutes at 100% load we arrive at a temperature that accurately represents our heatsink’s performance.

Sound

Sound levels will be measured with a Reliability Direct AR824 sound meter from a distance of four feet away. With everything turned off and the room completely silent the meter registered a sound level of 38dB(A). This is a very quiet room where a simple pin drop could be heard. All sound measurements are recorded in the very late evening to further reduce any ambient noise.
