Too big.

Feed it with 9V instead.

Won't break your fan but your control over speed may be quite course.

The details say range is 5 to 100%.

Your max power is less than 5%.

So may not work. Try it and see and let us know....

It's PWM. That should be insensitive to the load.

OK - I just find it difficult to believe that a $15 piece of kit is capable of a 40:1 turndown and not hunt at a very low percent of its possible output.

But maybe it does. It's only $15 FGS - just buy it and try it.
