Trying to follow this pwm fan controller guide...

I would suggest the following: Instead of playing with R1 and the VR/ADJ levels, I would suggest adjusting R3 and/or R2. If the last couple of LEDs are not lighting when you're at max fan speed, it means that the voltage going into pin 5 (SIG) on the LM3914 isn't getting high enough. Either increase the value of R2 slightly or decrease the value of R3 slightly, and put the rest of the stuff back the way it was.

Yeah, I forgot to post back, but I got it to work thankfully :). I changed R2 at 680 ohms to two resistors in parallel (5.6k and 1k) to get about 850 ohms. It works great.

Now, if only my linear regulator would go over 10V or so...but oh well, I doubt I will run my panaflo 120mm U1A's at 12V anyway, lol.
