My friend upgraded his case and fans so he just gave me his old case and fans. Looking for a fan controller that supports a 4pin input and 3pin fan control. My current mobo only has 2 4pin headers (1 cpu and 1 case) and all 3 of my case fans are 3 pin so I have just left my side panel off to let my gpu and cpu have access to fresh air. Anybody know of a controller that can do what I'm looking for? Controlling 3 pin fans via voltage but controlling them all with a 4 pin header. I have fiddled with speedfan and looked in my BIOS to see if it supported 3 pin fan control and sadly, no. If anybody knows a controller I could buy that would be great if you could leave a link, thanks!

Phanteks PWM fan hub should do the trick,
specs: http://www.phanteks.com/PH-PWHUB.html

Here's how Phanteks fan hub works.
It can hold up to 6 fans and all fans are powered by SATA connector. It also has 4-pin cable that goes from fan hub to the CPU_FAN connector on MoBo. All 6 fans will run in sync and without user interference, fans RPM change by the temp of the CPU.
You can see fan RPM from BIOS/ fan control software but you can only see Fan 1 RPM. If you change the RPM of Fan 1, the PWM signal is duplicated to the Fans 2- 6, thus resulting all fans to run at same RPM (provided that fans 2 - 6 can run at same RPMs as Fan 1 does).

This kind of fan hub is good when your MoBo doesn't have enough fan connectors and/ or you want all your...

If you want to control each fan separately then you'll need fan controller.
Here's one such controller that uses one 5.25" external bay: NZXT Sentry Mix 2,
specs: https://www.nzxt.com/products/sentry-mix-2

With this, you can control up to 6 3-pin or 4-pin fans individually.

For fancier fan controller with LED control panel (can hold up to 5 fans), look towards NZXT Sentry 3,
