How to connect a 555 IC PWM controller to a 4 wire 48volt dc Fan

[johe...@gmail.com]

I'm a noob. I have a circuit that use a 555ic to create a PWM signal. The fan I want to use is a 4 wire 48vdc fan that draws a max 350mA. Do i connect pin 7 directly to to PWM control wire of the fan?

Hi Johan,

I think you have hit the wrong PWM forums. This forums is for PWM ( open source password self service application for LDAP directories). This forums as nothing to do with Pulse Width Modulation.
