Thanks...I wasn't sure if the front fan or the rear fan(s) were
considered the "chassis" fan. The case fan connectors are four pin on
my case so unless I get new fans, can't be connected to the
motherboard. Right now I'm concerned about cooling the case and was
curious if the "chassis" fan would spin faster if it was connected to
the motherboard due to its rotation being regulated based on heat
build-up in the case. It's been pretty warm here so I've left the
door off the case until the temperature drops.
