In stock testing, there is very little to complain about when it comes to the thermal results. At 55-degrees, the Ninja 5 comes in just behind the AIOs at the top of the chart, and is dead even with the much more expensive NH-D15.
Losing some ground, but still hanging in there, when the overclock is applied, the Ninja 5 drops a couple of slots, and is now even slightly behind the well-Aged NiC C5. 71.5-degrees is still a very respectable result when compared the masses of coolers in this chart, so even if a tad behind the coolers we last compared it to, it is still the sixth best air cooler in the chart.
Landing yet again at the top of the chart, the Scythe Ninja 5 shows that they have the PWM fan curve set just about as good as it can get. With less than two degrees gained from running the fans at full speed, this will not make or break and OC, so you may as well use the Ninja 5 as designed, allowing the PWM curve to call on the fans as needed.
Noise Level Results
In stock clock testing, we saw the pair of fans spinning at 530 RPM on the front fan and 512 on the rear fan. At this time, all we get is 24 dB of noise, and with any closed case, you will not hear a peep from the cooler. Even in an open-air setup, you have to get right on top of the cooler to hear anything at all.
Overclocking the CPU brings the PWM curve near the top end, and delivered 26 dB of noise. At this time, the front fan was spinning at 624 RPM, while the rear fan is turning at 599 RPM. While not topping the past two charts, this is still under what most can hear from a foot away from the PC, and is excellent for those in search of performance in a cooler with very little noise involved.
Allowing the fans to top out with 12V applied to them, we only got up to 29 dB of noise. The front fan was at 800 RPM, which is the maximum rated speed, and the second fan was at 791 RPM. While we mentioned that supplying 12V to the fans was not needed in the thermal results, if you do choose to go this route, the noise is not much of a factor.
