Enermax LIQMAX II 240 Liquid CPU AIO CPU Cooler

Enermax is extremely proud of its Liqmax II 240 CPU AIO cooler. It is one of the few coolers you will find that it proudly displays its TDP rating right on the front of the box, which happens to be "350W+." With its Batwing fan blades, ceramic bearing pump, and Shunt-Channel-Technology it is a sure winner, right? Let's find out.

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.

Starting with our CPU at stock settings we see the LIQMAX II perform well but not well enough to take the top spot. What is most interesting is how close the temps are between having the fans at high speed and low speed. There isn’t a lot of heat going through the system so it’s somewhat expected. Let’s see what happens when we pump a lot more heat through the radiator.

4.4GHz Overclocked CPU

The LIQMAX II performed even better than I expected at overclocked speeds! Enermax coolers have had tough times in our tests but that might be a thing of the past now. Also, because there is a lot more heat to dissipate there is a bigger delta between the fans at full speed and the fans at low speed.

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.

Starting with the fans at their quietest, the noise they produce is faint and easily dismissed. This would make for a great bedroom setup. On the other hand, if you need to turn the fans to their maximum speed you’ll be greeted with a lot more noise. Enough noise to prevent you from using the fans at this speed without headphones. Truly, they produce a lot of noise. This isn’t a deal breaker since you have the option of fine tuning the fans through either the switches or separate software control. So what does this all amount to? Next page please.
