I use a 100 Ohm 5W rheostat to undervolt each of my Panaflow (120's and 80's, L1A's and H1A's) case and CPU fans on a one-to-one basis. No voltage regulator, no PCB, minimal soldering to set up. A variation of Cliff A's original setup (that's where I got the idea). No trouble for over a year of almost 24/7 use. They don't seem to get hot, and the fan speed range is perfect.

I have seen some of the senior members promote the fancier undervolting solutions (commericial or homebrew) as safer/more reliable. Can someone enlighten me as to why?

Thanks!

Me? :roll: Yeah, i was using the normal variable resistor... Your meatier 5W reostats will be fine. Mine were about 0.4W i think! Sorry for any confusion/worry! If i could find some of those higher current ones, i would use them too! exactly like you do!
