First of all: I got my account back! Yeeeeha!
One of my case fans has either a bad bearing or a faulty motor. It was used to move hot air from the CPU-cooler out the back of my case. Color does not matter unless it is pink with green LEDs. Looking for 120mm 3pin fans.
I have been looking at one of these:
Noiseblocker eLoop B12-3
BeQuiet PureWings 2
Noctua NF-P12
Open for other suggestions
