Well good new and bad news.

I was out with my friends and stopped by a local electronic shop and picked up a cheap 40mm fan for $1.00. It works perfectly! So I guess the first fan I bought is...

Don't worry your advice has not gone on deaf ears. I have been busying studying for school.

I got 20 mins to play with it today and I found which two wires are the black/red using your method....

Do I have to update firmware or am I just stupid?
