Hello. I was cleaning out my cpu fan about 20 mins ago, and one of the fins had cracked. It was bending too much, so I broke it off to prevent it from damaging anything. Well, now the CPU fan is vibrating, and I'm scared...Will the vibration kill the CPU? Where can I get a new stock CPU fan? I'm running a P4 1.8 gHZ Willamette with stock fan spinning at 3750 RPM.
