The 800 RPM Slip Stream is also very impressive. For those who don't want to muck about with fan control, it can be run at full speed and be inaudible in the majority of systems. It's very quiet and can be made dead silent with a bit of undervolting. Like the 1200 RPM model, it has a low starting voltage and good acoustics across its range. Very smooth and quiet all the way up to 12V.

It did not quite match up to the Slip Stream M in performance, falling a few CFM short, but basically tied the Nexus fan. Interestingly, a Slip Stream L shipped with the Scythe Ninja Copper, and in our review, it performed better than the Nexus fan by a couple of degrees.

If 800 RPM is not low enough, Scythe also has a Slip Stream fan that spins at a paltry 500 RPM. In all the but the most silent of systems, the SL seems to be a pointless investment. Through its entire range, the noise level never broke the ambient level in the room, as one would expect. It did however click at low speeds, though why anyone would run it below 12V is a mystery. The SL will be drowned out in anything but a passively cooled system.

There was some variance in our batch of samples, with some clicking more than others. Unless there was something wrong with the shipment we received, buying an SL model Slip Stream may be a bit of a crapshoot.
