For a little project I need some super low speed SLIM 120mm 500rpm fans. So i had undervolting the 120mmx120mmx20mm 1350rpm yate loons in mind but they only undervolt to 6v (consistently apparently) which based on a quick bit of reseach means they will spin at around 800rpm ... I want quieter!
So I was wondering if I bought a BigNG which allows you to pwm fans do you reckon I could get them close to 500rpm without any horrible ticking noises?
