50mm is a really odd fan size, and it turns out that there are NO PWM fans available in this size.
That left me with the idea of putting a smaller fan (but enough CFM) in a larger opening, if I could find or devise a step-up-adapter or make one.
Ideas?
Thanks.
40mm fan in a 50mm opening?

Re: 40mm fan in a 50mm opening?
The extra rotation speed needed to shift air will make it much louder. Probably better to run a 50mm slower than a maxed out 40mm.
You can get PWM-DC adaptors. I have one which is specially made by this company but I'm sure others may be available:

I've contacted the vendor for a datasheet / added info. It looks like an interesting potential solution.
