3pin fans into Lamptron FC5V2

post #1 of 7
Thread Starter 
I want to match like a nerd and swap out my other 140mm fans for more xigmatek fans, the problem is the 140mm xlf fans are 3-pin unlike their 4 pin 120mm brothers,

thus my question is will I not get RPM read outs on the display or will everything still display fully even though they are 3 pin and that is what I understood the 4th pin was for, RPM/Fan Speed Control.

3 pin - red 12V, black ground, yellow rpm.
4 pin - red 12V, black ground yellow rpm, blue - PWM function

So yes, you will get an RPM read out with any of the fans. The fourth wire is to control the fan motor by PWM, rather than by voltage. Hope this clarifies things.

Thanks man, so to my understanding then I am good to go as the fan controller does it by voltage, and the read outs will all be accurate

Yup, thats right. You will get voltage and rpm readings.

I use a Lamptron FC-5v2 and all my fans are 3 pin and it displays properly. btw..IMO it's the best fan controller available
post #6 of 7
does anyone know where to buy the Lamptron FC-5v2 in Toronto, Ontario Canada?

You can get them from NCIX.com. They sell out fairly fast when they get some in, but you could give them a call or send them an email to find out when they'll get more. You could always buy them from the US though if you don't mind spending the extra cash.
