Thermal Results

Sixty-one point five degrees does not show well in the chart and appears to be something we would not be happy about. While we did want better performance from the GKC3, we are still nineteen degrees cooler than an Intel stock cooling solution.

Roughly ten degrees from the lead, and slightly less to the worst performing cooler on the chart, keep in mind that the Intel stock solution failed to run this test. The seventy-six point two five degrees is right in the middle of the pack.

We also test to make sure that the PWM control of the fan is up to par, and we do this by pushing 12V to the fan to gather the best result possible. In the Grand Kama Cross 3, Scythe left only two point five degrees on the table, but much noise accompanies this small gain.

 

Noise Level Results

In the stock thermal test, the PWM circuit only called for a maximum of 550 RPM, which is only 150 RPM beyond the idle speed. The 25 dB result at this time is impressive, as many do favor silence in their cooling options.

Still, under the control of PWM for the first overclocked thermal test, we recorded the fan speed to top out at 1086 RPM. The noise level does move into the audible range at 34 dB, but if more than a foot from the PC or inside of a noise absorbing chassis, the noise will not bother you much at all.

Allowing the fan to run at full speed, 1340RMM in this instance, we can see why Scythe opts for the lower speeds of the fan. The noise level jumps to 52 dB at this time, and is a droning noise that even the best chassis cannot silence.
