have a fan question
Howdy all,

I've got a number of 120mm fans and I'm going to be sleeving them very shortly. I am going to be attaching them to rads in a push/pull and I wanted to be able to turn them on and off using one switch on my fan controller (i have 6 available)

they are all medium speed fans, unsure of voltage and stuff. my question is how many of these fans can i attach to a single 3 pin connector given that my fan controller provides either 25 or 45 w per channel (6 channels.)

Many fans list their current rating on the decal. If they don't you can "guesstimate" on the high end by assinging each one with .5A fairly safely. There might be a few fans out there that go above that rating, but the great majority are under .5A.
