Title: Speed control with 2 wire fan?
Post by: David Stodolsky on December 29, 2009, 05:43:53 pm

Is there any way to control fan speed with a 2 wire fan. Rewiring the connector is no problem, but will the F6 BIOS rev up the fan when temps rise? The CPU fan is working fine, but I have three case fans that need control.

Hi,
http://www.spodesabode.com/archive/content/article/fanbus,
less than a pound,
You can move pins around to get 5v- red to black on molex but make sure fan starts ok,
                                                     7v- red to yellow
The bios wont speed up fans as they are run from the 12v rail,
there are a few other incl one for motherboard fan control,

DONT BLAME ME IF YOU FRY ANY OF YOUR BITS THOUGH,
Have fun and enjoy
I'm Just building 3 fanbus for my new case
