Fan Speed Controller - Build your Own

~Lordbob

I already have a Scythe Kama controller, but it will only reduce a fan's speed, not increase it. That would mean that I would have to get a very high speed fan in the first place, and then step it down as needed.

Nothing wrong with that idea, except that would require me to rig a cable long enough to reach the rear of the case, which none of my current cables will.

I'm sure that once I finish playing with it, it will remain set at one speed, and not require frequent adjustments. Therefore a switch on the fan would be adequate and a lot simpler.

True. Nothing wrong with being able to crank it up though.

When were you told that? :)

I don't recall mentioning that.

+1 for Noctua fans though some consider them expensive. That's a debate for another time :)

I just picked one of their fans at random, and while it is interesting, it's specs are confusing.

Unless I'm missing something, it's high speed airflow is 110.3 cubic meters per hour, and that works out to 992.7 cubic feet per hour, thus only 16.545 cubic feet per minute. If I'm misunderstand, please enlighten me.

I actually have that fan on my CPU cooler - Noctua NH-C12P SE14




While I haven't worked out the math, I can say pushes a lot of air and is very quiet, even without the adapters.

I know this doesn't answer the "math" question, but I can vouch for it's "performance"

I think i just had a tender moment that is beautifull man

Ciara, That fan has crazy output but man so is 65db have 3 or 4 of those things running and I would need head phones to compute.

Yeah so am I but I'm not proud of that !
