Best for
Cheap, low-power summer cooling for small and medium tanks that only run a couple of degrees too warm.
Worth knowing
Evaporative cooling means you will top up water more often, and fans only knock off a few degrees.
What stands out
- Adjustable-angle clamp mount
- Guard over the blades
- Mostly 12 V DC; FS-120 also in mains
- Multi-fan bars (FS-602 to 606) for long tanks
