The fan can be mounted on any side of the heatsink depending on how the airflow works in your case. Normally this would be so the fan is above your RAM and blowing toward the exhaust case fan. Conceivably you could mount a fan on both sides in a push pull configuration like some other heatsink designs but I didn’t test this since most modern PC cases have a 120mm exhaust fan very close to where a second fan would be located. It would be nice if Scythe included two extra clips just in case you wanted to try it.

One thing to note about the fan installation, while the clips are pretty easy to use once stretched out, they require the holes on your fan to be free of each other. The fan that came with my Ninja Plus rev. B had a channel connecting the holes on both the top and the bottom. The clips that came with the Ninja 3 would not work with that fan. The Ninja Plus rev. B fan clips wrapped around the outside of the fan so it didn’t matter whether or not the channel was there. One downside to that is you were stuck using the same thickness fan whereas the Ninja 3 brackets will let you use thicker fans like the Panaflo as long as the holes aren’t connected.

The included Scythe Slip Stream 120mm PWM fan, model SY1225SL12HPVC,  is rated at 470-1900 RPM, 7-37dBA, and 23-110CFM. The fan also has a potentiometer that fits in a PCI slot so you can adjust the fan speed without PWM or set two ranges for PWM to operate in, 470-1340rpm and 740-1900rpm. The fan is sleeve bearing and, in my subjective judgment, almost inaudible when set to low speed. It does get quite a bit louder at full speed but my testing shows that you will rarely need to keep it running at maximum. I would have liked to see the PCI bracket be optional as some people would like to sacrifice that extra control for having one less wire in their case. It is also annoying when it is dangling around while you are trying to install the motherboard in a case.
