I just purchased a cooler master sickle x flow 120mm fan for my PC, I have attached it to the side panel as the screw's won't fit in the front end of my pc. The sound from the fan is extremely loud and is connected through a molex 3 pin adapter. I changed the 3 pin rear case fan to the molex adapter and the sickle x to the motherboard fan pins and that made it a bit quieter. When I put my hand just infront of the fan its is whisper quite like it should be. What's the problem here? I tried reversing it and that didn't help either. Here's a picture of the setup.
Thanks Tom
