How We Tested
We tested the cooler with an FX-8350 CPU (eight-core, 4.0 GHz), which is a socket AM3+ processor with a 125 W TDP (Thermal Design Power). We configured it to run at its stock 4.0 GHz (200 MHz base clock and x20 multiplier) with 1.35V Vcore.
We measured noise and temperature with the CPU under full load. In order to get 100% CPU usage in all cores, we ran Prime 95 25.11 with the “In-place Large FFTs” option. (In this version, the software uses all available threads.)
We compared the tested cooler to the AMD stock cooler, with a high-end air cooler (Cooler Master Hyper 212 EVO) and an average air cooler (PCYES Zero K Z3). We tested each cooler with the fans connected to the motherboard and set to automatic speed control. The Wraith was also tested at full speed.
Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings.
During the tests, the side panels of the computer case were closed.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed near the top of the case. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.
