Modding Noctua P12 fans to be PWM?

[rfkrocktk]

I bought a lot (7, actually) of Noctua P12s for my most recent build, and only realized the benefits of having PWM after they got here. Is there any way for me to mod them to support the additional PWM pin? I've heard of other people modding non-PWM fans to add the additional pin to make their fans run slower when idle.

I doubt you can modify the fans to PWM but there are ways to control them with PWM using a PWM adapter. Where are you loated on our big blue marble?

California.

I know a guy in United Kingdom who makes adapters. But that's a long way from California.

He doesn't sell them online?

Maybe this link will help, it's a how to on gentle typhoons, maybe it will work on the Noctua's

No. He is not a business. Just a normal electronics guy. You have a private message.

Those Gentle Typhoons are PWM but not wired as PWM.

Could someone explain to me why a company would do this? Seems like a waste of money to buy and enable an ability but leave out a part(s) to allow the end user to use this ability.

Or are there Fans that do have the part(s) and they are marked up in price? *edit*

I've manufacturers do this on many different products over the years. Sometimes is planning ahead for future upgrades, sometimes it's a line of several models and they use same circuit board in all with different jumpers for different models. At a guess it's because they had the PWM circuit board/motor so just used it.

If you are you asking OP he already said.
