Safe to run Delta Fans off MOBO fan ports? - Page 2

post #11 of 12
As has been said above, do not try to run that much current through your MB, bad move.

Just get a lamptron.

(say that 5 times fast)

But you can try it anyway.
I've had times where you have to tweak the program to make it work by going into the Advanced tab and manually selecting Software Control for the "PWM mode".

I've never had an issue that I couldnt control a fan (unless it had no smart fan capability to begin with i.e. the 3 pin ports on my Gigabyte have zero control, BIOS or software).

Speedfan does not usually work with OEMs due to special BIOS/mobo designs.

@OP: i would not risk running a delta from a mobo fan header, even if it was within the amp requirements. Run off of a fan controller to be safe.

This sunbeam controller lets you use your computer for PWM input, so you can still have your fans automatically controlled.
