The 40mm is usually fitted to a heatsink, so instead of just cooling one side of the motor it is a little more even.
It will also shift a hell of a lot more air than any 25mm fan.
But if a 25mm is easier to fit for you then fine.

P.S. I meant less than half the price of Much More's 40mm fan, not 25mm
