Thermally, things start well for the ZOOMFLOW 240. As you can see, by the 55-degree results we got at stock, it competes with many of the other similarly sized AIOs on the market. The thorn in everyone's side is still the Scythe Ninja 5, but it is not a sealed loop cooler, nor does it offer RGB illumination.
With the use of PWM control of the fans and the OC now applied, the ZOOMFLOW 240 shows to have some deficiencies. Dropping from the top portion of the chart to near the middle now, the 72.25-degree result is less than seven degrees from the best option on the chart, but delivers little excitement for the box claim of "best cooling performance in the market."
Allowing the cooler to do what it can with no limits in place, we see that another two degrees can be had from the cooler. Even so, being bested by $50 air coolers makes the decision a tough one to jump at this AIO, even with the gap to first place tightened to near five degrees now.
Noise Level Results
Getting it out there upfront, in all tests we used the SATA power connection, so that the pump ran at full speed, and testing it with the 4-pin connector, we saw 2080 RPM listed for it in AIDA64. The pump at full speed delivered 26 dB. To result in the 31 dB mark we saw in stock testing, we saw the fans spinning at 1080 RPM as the maximum, and even though it is in the audible scale, inside of a chassis, it will not be much of an issue at all.
Swapping to the overclocked CPU state, the fans increased their maximum speed to 1200 RPM, delivering the 39 dB rating. At this point, even in an enclosed chassis, it will be heard, but with any music, game volume, or with a headset on, it is still little to be worried about.
To obtain that extra couple of degrees of efficiency, your ears will take the heat from it, as the noise level increased to 49 dB at this point. The average user is never going to opt for this type of gains 24/7, as the decrease in temperature is not going to amount to anything worth the effort.
