120mm Fan Testing on an MCR120 Radiator Round 6

Scythe Slip Stream High Speed

Thanks to Hondacity for sponsoring the fan..

I've had this fan in my collection for a while, I've always liked the high numbers of blades.

NOISE LEVEL
Almost spot on the same as the yate medium which is good

NOISE QUALITY
I'm going to say average to below average. It has some pretty good areas where the sound is fairly smooth, but it also has some very faint motor buzz/tick on occasion. Nothing really pronounced, but there is some motor noise there. The higher number of blades does seem to smooth out the air a little bit, but I think their steeper pitch and minimal forward sweep isn't making the air noise as soft as it could be. Listen to the video for your own interpretation, noise quality is always pretty subjective.

EFFICIENCY
Poor, this fan is extremly power hungry per CFM. I almost had to switch my Amp meter from milliamps over to Amps as it approached hitting .4AMPs at 12V which is 4.5 watts where the yate medium is only drawing about 2 watts. You definitely want to check those fan controller specs before stringing a bunch of these together.

CFM/RPM
Seems to be a little better than the yate medium with the higher number of blades which is good.

OVERALL
Good, pretty similar to the yate medium with a bit more top end and less low end range. The only thing to really watch for is the power consumption which is almost 5 watts.

Scythe SlipStream High Speed-V (Vapor Sample)

Special thanks to Vapor for providing this sample. The one I tested previous was actually being used as a case fan for a little while, so it was good to get a nice fresh sample to compare.

It came in fairly close +-1dbA, but this test did perform better. Noise quality is much the same, so I'm not going to bother with rendering another video.

Anyhow, here are the results, I'll add this information to the original sample post. In general this sample shows a fairly strong CFM/dbA at lower volts compared to most fans, and sort of creeps up into the pack at 12V. Noise quality wise, I don't think it's quite as good as the yates for example, but it's all fairly close and subjective. It is a power hungry little fan though, all 4.5 watts much like the other sample.
