Mild OC Testing
For our Mild OC testing, we have configured our CPU to run 4300MHz on all cores, set the voltage to 1.15V, and configured memory to XMP mode. This yields an approximate power at the wall of 450w under load (a 350w differential from idle, which pulls about 100w). This results in the CPU running at 4.3GHz on all cores during the looping rounds of Cinebench R20. You can read more about this in our introduction article here.
Max Fans – 100% Pump Speed
With the kitchen heated up to a mild overclock, we see the DeepCool LS720 towards the back of the pack at 74 degrees Celsius. On the plus side, it outperforms the DeepCool CASTLE 360EX by a couple of degrees, but the MSI MEG CORELIQUID S360 takes the crown at 4 degrees cooler.
1500 RPM Fans – 100% Pump Speed
Pulling the throttle back to 1500RPM, we find the DeepCool LS720 bringing up the rear at 79 degrees Celsius. This isn’t exactly a good look for it though, it will be interesting to see what the acoustic trade-off is for this performance.

Finally, at our lowest fan speed for our Mild OC testing, we find the DeepCool LS720 at the rear once again, hitting the 88 degrees Celsius mark. The balance of the competition performed 2 to 5 degrees better.
Max OC Testing
For our Max OC testing, we have configured our CPU to run 4700MHz on all cores, set the voltage to 1.25V, and configured memory to XMP mode. This yields an approximate power at the wall of 600w under load (a 500w differential from idle, which pulls about 100w). This results in the CPU running at 4.7GHz on all cores during the looping rounds of Cinebench R20. The only test that was completed without throttling was the Max Fans and 100% pump speed test. You can read more about this in our introduction article here.
Max Fans – 100% Pump Speed
For our last test, we see the DeepCool LS720 join many AIOs prior to it and fail the test. Note that our pass rate on this test (defined as “does not kick in thermal throttling”) is less than 50% on units that we’ve looked at since we started using this test bench.
Now that we have seen how all of our units cool, let’s see if we can still hear!
