Turbo was enabled for the stock tests as we always do, this will take the 4.0Ghz to 4.20Ghz during the stress test.
We used the default PWM setting for the testing. The fan profile is bottom middle of the screenshot.
Sound Level Testing
We used a standard generic digital sound level meter at 15 inches. It is important to note we used the Lian-Li PC-T60 Test Bench for testing which is an open chassis. This means you are hearing the CPU coolers fan unobstructed.
