Right out of the box, and allowing the cooler to do what it does without any messing about with it, the performance starts off strong. At 55.25 degrees, the MasterLiquid 240 comes in at a respectable fourth place with the coolers we have tested thus far. We should mention, that for this, and all following testing, we did run the pump at full speed, which was reported at 948 RPM.
Applying the overclock, and still allowing for PWM control of the fans, the temperature jumped to 72 degrees, which is not all that bad in the grand scheme of things. However, the MasterLiquid 240 has fallen from fourth to sixth place in this test.
Attempting to gain every ounce of performance out of the cooler, pushing the fans at full speed, we see there is a slight reduction in temperature. The 70.25-degree result keeps the sixth place position in this run, but also shows how close the PWM fan curve is to delivering the most from this cooler, without having to deal with all the noise this test method presents.
Noise Level Results
As it is displayed in this chart, with the pair of fans turning at 1147 RPM, the 30 dB of noise seems high, but in reality it is not all that bad at all. Most descriptions of noise levels will tell you that this is the beginning of human hearing, and while we could hear a slight hum from the fans, we would in no way call this result loud.
When we applied the overclock, the PWM circuitry did ramp up the fans slightly to 1636 RPM. At this time the noise does increase to 38 dB, which is noticeable in the room, but still not in the droning range of noise, and inside of a chassis, with sound directed away from the user, the noise is even less noticeable.
To obtain the best performance, we do not feel the extra 1.75 degrees we saw in thermal testing is worth the amount of noise produced to achieve it. At 69 dB with the fans turning at 2547, there is no way to disguise this amount of noise. Even with headphones on while gaming, you are going to hear the MasterLiquid Pro 240 if you choose to run the fans at full speed.
