This is a newer section that we’ve added into the cooler reviews just to get a little more insight on what you’re getting yourself into for power consumption. It’s only fair to check out how much each cooler consumes compared to stock, so we’ll take a look at both idle and load numbers.
Each cooler will not have any power elements disconnected, unless otherwise noted; rather they’re introduced to help you understand the power consumption differences between the coolers when they’re fully functional.
To do our measuring for power consumption, we’ll be using a Kill-A-Watt meter hooked up to the computer only, we’ll let the system sit idle for 15 minutes after boot to allow it to settle down and take a measurement then. The average whole number that the meter is displaying is the number that we’ll use. We’ll then load up Prime95 to put a full load on the CPU to get each core and thread to work as hard as they can, grabbing the power consumption numbers in the same way. All tests are done at the stock turbo frequency of 3.9GHz on the i7-4770k.
Overall Results: Power usage is spot on with just about every cooler at idle, and this is exactly what I come to expect with liquid coolers. The load usage was right in the middle of every other cooler, with the system coming in at 199 watts used.
