I have 6 x 3pin fans in my PC case that I want to connect to. I can find PWM fan hubs but these will only run the 3pin fans at full speed. I could not find a fan hub that is capable of low med high speed control of 3pin fans. Anyone has any suggestion? Thanks!
Please Recommend a PC Fan Controller Capable of High, Med & Low Speed Control of 3pin Fans

Thanks for reply. I don't thin 3 pin fans allow for PWM operation. I think these will run full speed only. There are those ones with rotary dial but I could not install those as my case has no 3.5" and 5.25" slot.
Thanks. Interesting read that one. Looks complex to me however.
No. The controller it’s self is being set through a four pin pwm. And you can set the speeds through that, the controller then regulates the power going to the three or four pin fans. You don’t control each one nor can you see how each fan is running, just got to play it by ear so to speak and go off the noise levels you wish to achieve since you don’t know each fans rpm range.
Also I use the thermaltake commander to control the fans on my radiators. It’s simple enough to use just attach it to a pwm on the motherboard and go from there.
But if the mobo supports tuning doesn't the 1 PWM fan report the "Fan" speed to the tuning program? That is
The tuning program allows you to set fans at quiet, normal Turbo speeds and manually anywhere you want if the mobo pwm pin is the controller for everything hanging of it then you could get an even fan response across the 6 or more fans I have not seen a need for case fans in general to all run at different speeds ? and GPU fans are set independently as are CPU fans ?
@ShannonN: you will find that fans all run at different speeds, even ones that are the same brand and models can have variations in the rpm they can achieve. Yes using tuning software you can set each fan if they are attached to your mobo but when they run through a fan controller they are being controlled by power not rpm so since each fan is different . I use Corsair ML 120 fans on my radiators max rpm range for the fans is between 2100 rpm to 2500rpm though advertised as a max of 2100.
My way of dealing with it is use a 4 pin to the fan controller and make a profile in speed fan that reacts to the heat of my gpu which controls the fan speeds. The speeds them self are not being controlled just the controller is being told to give them more power to make them faster. The fans not on the fan controller you can set their own profile and control them by speed.
The Phanteks PWM Fan Hub is capable of powering up to 11 fan max (additional splitters required) 3-pin through PWM modulation, while occupying only 1x 4-pin header on your motherboard per fan hub. It's easy to install, comes with pre-drilled mounting holes to fit your Enthoo case or strips for use with other cases and keeps your interior clean by centralising all your fan cables.
